Discontinued Speakers Still Worth Buying Used

81 discontinued speakers that still rank in the top third of their class. Being out of production says nothing about how a speaker measures, and several of these still beat almost everything currently on sale in their size.

The store holds 288 discontinued speakers in total. The rest stay in the main rankings where their position speaks for itself; this page is the shortlist worth hunting for.

Why This Page Exists

Most review sites delete a speaker the moment it stops earning commission. That’s a bad deal for readers, because the used market is where the value is: a speaker that launched at $250 and measures better than today’s $150 models is a genuinely good buy at $90, and nobody will tell you so.

Two of the entries below are unusually stark. The EarFun UBoom X is still the top-ranked boombox on this site, out of 68. The Soundcore Motion+ ranks third of 133 medium speakers. Neither is in production.

What To Check Before Buying Used

The battery is the real clock. Lithium cells degrade whether or not the speaker gets used, and on most portables the battery is sealed in. A five-year-old speaker with a tired cell is a mains-powered speaker. Ask the seller for a runtime figure at moderate volume rather than trusting the original spec, and treat removable-battery models as worth a premium.

App and firmware support can disappear. Several speakers here rank where they do only with a manufacturer EQ preset loaded. See the EQ presets page. If the app is pulled from the store or drops the model, you lose the tuning that made it good. Check the app still lists the model before committing.

Wi-Fi and streaming platforms rot faster than hardware. A discontinued Wi-Fi speaker can lose services it was sold with. Anything with an analog or optical input survives that; anything that only streams may not.

Multi-speaker pairing is generation-locked. If you plan to pair a used speaker with one you already own, check they share a system, and note that even JBL’s own generations don’t interoperate. See multi-speaker pairing explained.

Water resistance ages. Seals harden and port covers get left open. Treat an old IP rating as a claim about the speaker when new, not now.

No warranty, and often no parts. Price accordingly. For anything expensive, that argues for a returnable marketplace over a private sale.

Is The Newer Model Actually Better?

Often not. Several head-to-head comparisons on this site find the newer generation ranks lower than the one it replaced: the JBL Xtreme 4 against the Xtreme 5 and 3, the Tribit Stormbox Blast 2 against the original, and the B&O Beosound A1 3rd gen against the 2nd. Check the comparison before assuming the upgrade is one.

Ranked #5 of 47 in Small Size Portable Bluetooth Speakers, last listed at $40 - Tribit Stormbox Micro: $40 Discontinued eBay

Pros: Quite neutral. Slight hollowness in the mids. Built in strap is super useful for attaching it to things. Highly recommend spending the extra $10 for the Micro 2 which goes louder and deeper. To have it aimed directly at you unclip the strap and the speaker will sit upright with a slight lean back. Measured bass extension of 62Hz (-10dB).

Cons: Gets murky and slightly sharp near max volume; boosted bass distorts when pushed loud. Down-firing passive radiator needs a flat surface underneath or the bass gets muffled. Discontinued and no longer sold new; superseded by the Stormbox Micro 2. Discontinued.

Pros: Lights on top. Deeper bass than most other speakers in the size. Measured bass extension of 58Hz (-10dB).

Medium Size Portable Bluetooth Speakers

Ranked #3 of 142 in Medium Size Portable Bluetooth Speakers, last listed at $79.99 - Soundcore Motion+: $79.99 used, Discontinued Amazon eBay

Pros: The previous best sounding in class, still a great speaker with separate tweeters, more bass at full volume and better off-axis treble frequency response than the Uboom L. Just okay with the default EQ, I highly recommend using this EQ setting from r/kai7895 to get it more neutral. To achieve the absolute best sound you’ll need the Wavelet app (Android only) and set the provided Wavelet EQ in there too. Turn off the wavelet EQ for outdoor use. An alternative is Oluv’s EQ which only needs the Soundcore app EQ. Measured bass extension of 54Hz (-10dB).

Cons: Not quite as neutral or detailed as the Uboom L. Without the above EQ, this speaker will rank around #25 in the rankings. Discontinued.

Pros: A very neutral good sounding inexpensive small speaker with quite deep bass for the size. This upgraded version has a usb-c port while the old one has micro usb. Measured bass extension of 56Hz (-10dB).

Cons: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video. Discontinued and no longer sold new. Discontinued.

Pros: One of the early Bluetooth speakers with excellent all-around sound quality, very neutral and great soundstage. Deep bass without distortion at high volumes. IP67 waterproof and dustproof rating. USB charging port charges mobile devices. Built-in stand on back for sturdy tilted positioning. Measured bass extension of 57Hz (-10dB).

Cons: Expensive. Treble is rolled off. Phantom battery drain issue, would not recommend these days. Uses some stereo enhancement reverb that can sound weird to some. Not as detailed as higher ranked speakers. Discontinued.

Pros: Pretty neutral sound, slight upper mids peaks. Measured bass extension of 20Hz (-10dB).

Pros: Use Oluv’s EQ for the flattest response. Measured bass extension of 65Hz (-10dB).

Pros: Very balanced sound. Measured bass extension of 47Hz (-10dB).

Cons: Not stereo, app is buggy. Wireless TWS pairing is buggy. Not easy to carry on the go, no handle and there’s 2 pieces. Calls itself splash resistant but has no official water rating. A bit expensive. Has reliability issues more often than any other speaker. Discontinued.

Ranked #9 of 78 in Large Size Portable Bluetooth Speakers, last listed at $100 - Mifa Wildbox: $100 Discontinued eBay

Pros: A really neutral frequency response across the midrange. 6 different lighting modes, or turn off the lights with a long button press. You will need to upgrade it to the latest 2.11 firmware with a Windows PC, as it likely ships with 1.93. Sound quality and bass extension on previous firmwares wasn’t very good. To upgrade firmware, install the PC flashing tool and download firmware. With the speaker off, hold V+ Play V- at the same time to enter flashing mode. To check firmware, turn on the speaker, quickly press the M button 3 times, then quickly press the Play button 3 times (it can take a few tries). Measured bass extension of 45Hz (-10dB).

Cons: Doesn’t seem to be available anymore. No app. The slightly boosted upper treble can be slightly fatiguing on-axis with certain songs. Some of the buttons can be confusing, “M” is the Bluetooth button and skip song is long press play, while repeat is double press play. The plastic case isn’t textured or rubberized like other speakers and some may find it feels cheap. If dropped it may break internally and sound strange. I’d recommend only buying it from a place with free returns just in case it was damaged in shipping. Discontinued.

Ranked #15 of 78 in Large Size Portable Bluetooth Speakers, last listed at $80 - Soundcore Select Pro: $80 Discontinued eBay

Pros: A tough 1.5kg speaker with IPX7 protection, app EQ, a claimed 16-hour battery life, USB-C charging, power-bank output and PartyCast for linking up to 100 compatible speakers. It reaches a useful 106dB maximum level and offers a lively, bass-forward sound for casual outdoor use.

Cons: Independent lab listening finds only fair music fidelity: bass is somewhat boomy and lacks deep extension, mids can sound nasal and congested, and treble becomes smeared or sizzly. It strains at high volume, lacks an aux input and is discontinued, so it is best chosen for features and durability rather than detail or neutral sound. Discontinued.

Boombox Size Portable Bluetooth Speakers

Ranked #1 of 75 in Boombox Size Portable Bluetooth Speakers, last listed at $159.99 - Earfun Uboom X: $159.99 Discontinued Myearfun eBay

Pros: Tuned by Oluv and he knocked it out of the park again. Deeper bass than the Stormbox Blast. Extremely neutral, possibly the best of any modern Bluetooth speaker slightly behind the Vifa Helsinki. This is the only speaker that sounds correct at every single volume level due to Oluv’s individual EQ settings at each volume level. Other speakers will need a different EQ at each volume level. Amazing sounding at low levels as it boosts bass and treble at low levels to account for the equal-loudness contour. Just considering the midrange and treble, this speaker is better sounding than the Earfun Uboom L. Measured bass extension of ~38Hz (-10dB).

Cons: The out of the box 0.33 firmware and EQ sounds horrible. Some people have mentioned sound interruption issues when using 2 in TWS, I don’t have this issue with my Pixel 7 Pro, try disabling AAC in that case. Discontinued.

Setup: Please update it using the Earfun app (Android or iOS) and select an Oluv EQ. The Earfun app has sound profiles created by Oluv for Studio, Indoor, Indoor+, Outdoor, Outdoor+, BOOM xxX, and Ground 0 which are all fantastic. Oluv has a newer firmware pack that brings it up a few more notches of neutral

Medium Size Powered Bookshelf Speakers

Ranked #21 of 65 in Medium Size Powered Bookshelf Speakers, last listed at $800 - IK Multimedia iLoud MTM: $800 per pair Discontinued Amazon eBay

Pros: ASR’s measurements of the original MTM give scores of 4.07 standalone and 6.26 with an ideal subwoofer, a 2.4dB midrange response span and a -3dB point around 53Hz. The small cabinet, balanced input and calibration capability make it useful for close listening where larger monitors would be impractical. Measured bass extension of 50Hz (-3dB).

Cons: The MTM arrangement makes listening height and orientation important, while bass below the low-50Hz region still needs support. The native response is not as smooth as the best compact reference monitors. Exact compression ceilings and correction examples from the MKII review should not be assigned to this original version; its score describes tonal response, not maximum clean volume. Discontinued.

8-Inch Two-Way Powered PA Speakers

Ranked #3 of 15 in 8-Inch Two-Way Powered PA Speakers, last listed at $500.00 - Turbosound NuQ82: $500.00 Discontinued B&H Photo Video eBay

Pros: Low-quality vendor data still shows a 5.1 ideal-subwoofer preference score with 52Hz measured extension, the deepest bass reach of any 8-inch box in this ranking. The switchable passive/bi-amp design and coaxial point-source layout give installers flexibility on amplification and DSP. Measured bass extension of 73Hz (-3dB).

Cons: Being passive-by-default, it needs an external amplifier and crossover to work at all, and its 123dB peak claim trails every active speaker here. Discontinued.

Medium Size Bookshelf Speakers

Ranked #13 of 87 in Medium Size Bookshelf Speakers, last listed at $1500 - Revel M105: $1500 per pair Discontinued eBay

Pros: CEA2034 spinorama shows an essentially flat on-axis response with only a small 5kHz peak, a smooth listening window, and clean waterfall decay. Wide horizontal dispersion gives flexibility with toe-in. The reviewer called it reference-quality performance with minor EQ correction applied. Measured bass extension of 75Hz (-3dB), with a measured sensitivity of 85dB.

Cons: Low nominal impedance demands a capable amplifier that can handle low-impedance loads. Bass distortion runs high in the 80-250Hz range from woofer displacement, and maximum output is limited compared to larger designs. Discontinued.

Ranked #21 of 87 in Medium Size Bookshelf Speakers, last listed at $599 - Wharfedale Diamond 12.1: $599 per pair Discontinued eBay

Pros: A budget two-way bookshelf speaker (5” polypropylene woofer, 1” textile dome tweeter) that measures well for its price: harmonic distortion at 86dB stays under 1% THD down to about 60Hz, genuinely good for a 5” mid-woofer. Wide horizontal radiation of about ±60° up to roughly 5kHz before the tweeter starts to beam. Tonally smooth and easy to listen to at moderate volumes, with a pleasant, non-fatiguing character the reviewer said he’d happily recommend to someone who wants noticeably better fit, finish and looks than typical speakers in the $300-400 range. A high-pass crossover around 80Hz meaningfully cleans up midrange multitone distortion, so pairing it with a subwoofer helps more than usual for a speaker this size. Measured bass extension of 61Hz (-3dB), with a measured sensitivity of 84dB.

Cons: A dip of about 3dB in the 1-3kHz crossover region (on-axis, in the predicted in-room response, and even off-axis) gives the speaker a soft, “laid-back” character that noticeably saps attack and transient bite from drums, guitar and other percussive material - possibly an intentional BBC-style dip, but one the reviewer would still prefer tuned flat. Vertical directivity is unusually tight for this class of speaker, holding together only within about ±5° of the tweeter axis before a real hole opens up in the response, so seating height matters a lot more than on most bookshelf designs. Diffraction artifacts around 3kHz and 5kHz show up as differences between the listening-window and on-axis curves. Distortion climbs well past acceptable levels at higher output - harmonic distortion exceeds 3% around 150Hz at 96dB (versus under 1% at 86dB), multitone distortion tops 10% at 96dB/1m, and real compression sets in between 96-102dB (about 1.5dB of lost dynamic range around 300Hz at 102dB/1m, roughly equivalent to 92dB for a pair at 4m in a room) - a genuine limitation on how loud or how far away this speaker can be pushed. Measured average sensitivity (84dB) runs a few dB below the 87dB spec. Only a 5” woofer, so a subwoofer is required for real bass. Discontinued.

Ranked #26 of 87 in Medium Size Bookshelf Speakers, last listed at $350 - KEF Q150: $350 per pair Discontinued Amazon eBay

Pros: Two-way coaxial (Uni-Q) design with a 1” dome tweeter and 5.25” mid-range time-aligned in a single driver assembly, available in ported or sealed configuration. Exceptional soundstage depth, a hallmark of KEF’s coaxial designs that the reviewer says few other speakers match. Bass extension reaches into kick-drum territory, respectable for a compact bookshelf speaker. Resonances present in measurements are consistent across on- and off-axis readings, meaning they can be effectively corrected with EQ. Distortion profile is essentially the same whether run sealed or ported, since a subwoofer crossover point sits above where the differences would matter anyway. At its sale price (around $300, sometimes seen at $400), the reviewer considers it a clear step up from his previous budget favorite in this range, the Emotiva B1+, mainly due to the superior soundstage depth. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 85dB.

Cons: A high-frequency lift in the estimated in-room response makes it sound noticeably brighter in an untreated room than in a heavily acoustically-treated one - a real preference factor depending on your room’s furnishings. A mild dip in the 1-2kHz region reduces vocal fullness somewhat. Unexplained resonances appear in measurements and persist in both sealed and ported configurations, pointing to enclosure or panel vibration rather than the port. Horizontal radiation is narrower than the reviewer generally prefers from KEF’s lineup, with directivity that widens somewhat around 1.2kHz (near a resonance) and again above about 5kHz. Compression testing at high output (102dB) shows significant nonlinearity, especially at lower frequencies - noticeably worse than a comparable Arendal bookshelf speaker costing over twice as much, which held up better until 80Hz. Not intended for loud listening without a subwoofer - the woofer will over-exert itself without a high-pass filter, and the reviewer recommends crossing over at 80-120Hz. At full retail price (around $600/pair), the value proposition is far less certain than at sale pricing. Discontinued.

Ranked #28 of 87 in Medium Size Bookshelf Speakers, last listed at $299 - Wharfedale Diamond 220: $299 per pair Discontinued Wharfedale eBay

Pros: Amir found the on-axis response smooth once the grille is removed, calling grille removal “a huge improvement” since the stock grille caused unusually strong comb filtering around 5kHz. Good horizontal dispersion from the waveguide-loaded tweeter and controlled distortion. After some EQ (a room mode filter and treble shelf), the reviewer called it “a truly hifi speaker” where “every audiophile track…sounded very good,” and said he was “happy to recommend” it for the budget class. Measured bass extension of 117.2Hz (-3dB), with a measured sensitivity of 86.9dB.

Cons: Response rolls off below 200Hz, so a subwoofer is recommended for full-range use. Some port rattling was noted at high volumes, traced to vibration rather than the woofer itself. Best performance requires removing the grille and applying the reviewer’s EQ filters. Discontinued, with only limited remaining stock available direct from Wharfedale. Discontinued.

Large Size Bookshelf Speakers

Ranked #6 of 130 in Large Size Bookshelf Speakers, last listed at $3,995 - March Audio Sointuva: $3,995 per pair Discontinued eBay

Pros: The Purifi woofer and Satori waveguided tweeter combine class-leading distortion with unusually deep extension for a compact cabinet. Erin measured roughly 83dB sensitivity yet found the speaker could still sustain about 96dB/1m with 3% THD not crossed until ~60Hz; compression remains exceptionally low until the deepest bass at the highest sweep. Horizontal directivity is broad and smooth, the early-reflections trend is readily equalizable, and the passive radiators avoid port turbulence while reaching approximately 50Hz anechoic and lower in-room. Measured bass extension of ~50Hz (-3dB), with a measured sensitivity of 83dB.

Cons: Erin measured a 3.8-ohm minimum and an average load near four ohms; combined with ~83dB sensitivity, this demands a powerful four-ohm-stable amplifier even though the drivers tolerate that power cleanly. Vertical directivity shows the unavoidable woofer/tweeter crossover cancellation, so stand height matters. The original waveguide narrows somewhat in the upper treble compared with the later AWG revision, and the premium price is difficult to justify if low-level listening or an 80Hz sub crossover leaves the Purifi woofer’s excursion capability unused.

Ranked #9 of 130 in Large Size Bookshelf Speakers, last listed at ? - Revel M106: Discontinued eBay

Pros: CEA2034 spinorama shows a fairly even on-axis response with no obvious resonances, and a listening window that sits comfortably above the on-axis curve. Predicted in-room response is called “near ideal” by the reviewer, with a smooth downward slope from bass to treble. Distortion at 96dB SPL/1m stays well controlled through the midrange and treble. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 86dB.

Cons: Some directivity error and response variation shows up in the crossover region. Horizontal beamwidth of about ±50 degrees is on the narrower side. Vertical directivity requires staying within about ±20 degrees of the reference axis for accurate tonal balance. Minimum impedance dips to 4.6 ohms with several peaks, a moderately demanding load for a compact bookshelf speaker. Discontinued.

Ranked #29 of 130 in Large Size Bookshelf Speakers, last listed at €1,800 - Buchardt Audio S400: €1,800 per pair Discontinued Buchardt Audio eBay

Pros: Compact passive design with a 6-inch aluminum woofer, rear passive radiator and waveguided 0.74-inch tweeter positioned below the woofer. Erin measured F3/F10 at 53Hz/38Hz, approximately 86dB/2.83V/1m sensitivity and smooth, broad horizontal directivity. The waveguide controls crossover handoff effectively, the passive radiator avoids port chuffing, and Erin heard no objectionable narrow-band distortion despite excellent extension for the enclosure volume. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 86dB.

Cons: The impedance reaches 3.7 ohms (Erin), so a genuinely four-ohm-stable separate amplifier is recommended rather than a basic AVR. Low-frequency distortion naturally rises at high output and the compact woofer cannot supply theater-level deep bass; crossing to a subwoofer protects headroom. Erin measured narrow distortion features above 8-9kHz and vertical lobing outside the intended axis. This is the original S400, distinct from the S400 MKII already ranked. Discontinued.

Ranked #35 of 130 in Large Size Bookshelf Speakers, last listed at $2,899 - ELAC VELA BS 403: $2,899 per pair Discontinued eBay

Pros: JET 5 folded ribbon tweeter pairs with a 6” aluminum/paper sandwich woofer for extended, well-controlled bass - Erin measured usable in-room extension to about 50 Hz, deeper than JBL’s competing L52 Classic despite lacking that speaker’s mild upper-bass bump. Compression stays within about 1 dB above 100 Hz up to 102 dB, on the better side of normal for a bookshelf this size, indicating good dynamic and transient capability. Wide, spacious soundstage radiation. Overall neutral voicing that Erin called “a really good speaker,” from the looks to the sound. Measured bass extension of 59Hz (-3dB), with a measured sensitivity of 84.3dB.

Cons: Deliberate dip-and-peak voicing in the crossover region around 2 kHz reduces attack and clarity in the mids and highs - intentional per ELAC’s design, but not to Erin’s personal preference. Lower measured sensitivity (84.3 dB) means it wants more amplifier power than average to reach the same levels. Multitone distortion roughly triples, from about 1% to 3%, between 88 dB and 96 dB output, so it’s happiest at moderate listening levels. A minor distortion bump shows up around 800 Hz in the data, though Erin didn’t hear it. Discontinued and no longer sold new. Discontinued.

Pros: 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. Triple 8” Advanced Aluminum Matrix woofers deliver deep, authoritative bass extension down to an F3 of 37Hz and F10 of 28Hz with minimal low-frequency compression. Outstanding sensitivity (92dB SPL at 2.83V/1m) and ultra-low THD/multitone distortion allow extremely high undistorted SPL output in large home theater spaces. Measured bass extension of 37Hz (-3dB), with a measured sensitivity of 92dB.

Cons: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis. Vertical directivity handoff across the triple woofer layout creates vertical soundstage height tilt depending on listening distance and ear height. Minimum impedance dips to 3.8 ohms, requiring high-current amplifier stability. Substantial cabinet dimensions and 38kg weight require significant room real estate. Discontinued.

Pros: 12th generation 5” Uni-Q coaxial driver array with Metamaterial Absorption Technology (MAT) delivers remarkably smooth, controlled horizontal (±50°) and vertical directivity with near-identical off-axis tracking. Exceptional frequency response linearity through the midrange and treble that takes extremely well to minor parametric EQ adjustments. Constrained Layer Damping cabinet construction and flexible rear ports minimize enclosure resonances and port turbulence. Deliberately tuned low-frequency roll-off profile permits boundary-adjacent room placement near front walls without boomy acoustic buildup. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 86dB.

Cons: Low-frequency extension (F3 of 52Hz, F10 of 38Hz) requires pairing with a dedicated subwoofer crossed over at 80Hz for high-output home theater or bass-heavy music performance. High-frequency radiation above 7kHz shows a mild on-axis taper (1-2dB downward slope), performing best when listened to 10-20° off-axis. Moderate sensitivity (~86dB SPL average) requires a clean, robust 4-ohm capable amplifier to drive high dynamic peaks without clipping. Discontinued.

Ranked #10 of 71 in Large Size Floorstanding Speakers, last listed at $2,999 - KEF R5: $2,999 per pair Discontinued eBay

Pros: Slim three-way tower with the acoustic advantages of KEF’s coincident Uni-Q midrange/tweeter: horizontal and vertical off-axis responses track the direct sound smoothly, producing stable imaging and a well-behaved directivity index. Erin measured deep low-frequency reach for the cabinet width (77Hz F3 but 33Hz F10) and less than 1% harmonic distortion at 86dB. At 96dB it remains clean when high-passed, and its mild response deviations are suitable for equalization because the radiation pattern stays orderly. Measured bass extension of 77Hz (-3dB), with a measured sensitivity of 86dB.

Cons: The unusual gap between 77Hz F3 and 33Hz F10 indicates a gradual bass contour rather than flat deep-bass output; a subwoofer and roughly 80Hz high-pass are recommended for high-level playback. Erin measured a minimum near 3.5 ohms around 150Hz, although most of the curve remains above 4 ohms, so amplifier quality still matters. Sensitivity is approximately 86dB/2.83V/1m. At 102dB, compression reaches roughly 1dB around 150Hz, showing the limits of the twin 5.25-inch woofers. This original model lacks the Meta version’s MAT rear-wave absorption. Discontinued.

Ranked #13 of 71 in Large Size Floorstanding Speakers, last listed at $5000 - KEF Reference 203: $5000 per pair Discontinued eBay

Pros: An unusually accomplished 4-way design for its era: excellent on-axis linearity (within about +/-3dB), genuinely good directivity both horizontally (~55 degrees) and vertically (~40-50 degrees), and an estimated in-room response that closely matches what the reviewer actually heard. Distortion is excellent - under 1% harmonic above 80Hz at both 86dB and 96dB, and multitone stays around 1% even at 96dB. Bass reaches a real F3 of 51Hz (F10 37Hz), with in-room extension into the low-mid-40s. The reviewer’s overall listening notes were essentially “nothing stood out bad or good” - a genuinely neutral, accurate speaker with a distinctive rounded-baffle look that avoids the diffraction issues a flat baffle this wide would normally have. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 88dB.

Cons: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums) - condition, driver matching, and component aging vary by unit, so audition before buying if at all possible. Demands a robust amplifier: impedance dips to about 3.6 ohms with an EPDR of 2.2 ohms. The small supertweeter shows minor breakup artifacts at the extremes of the vertical polar plot and some compression at very high output in the top octave, though neither was audible in normal listening. Discontinued.

Ranked #14 of 71 in Large Size Floorstanding Speakers, last listed at $900 - Focal Chora 816: $900 per pair used, Discontinued eBay

Pros: CEA2034 spinorama shows a generally even on-axis response with nice bass extension and high sensitivity. Predicted in-room response is very good aside from a peak around 8kHz. Horizontal beamwidth of about ±60 degrees is typical and fairly controlled. Distortion is very low at 86dB SPL/1m and still usable at 96dB SPL/1m. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 91dB.

Cons: Some messiness appears between 500Hz-2kHz on-axis, including a dip around 550Hz. Vertical directivity narrows a little, so listening height matters more than with a coincident design. Cumulative spectral decay (waterfall) shows a fair bit of resonances lingering across the midrange. Distortion rises substantially in the 1-2kHz region at 96dB SPL/1m. Minimum impedance dips to about 3.9 ohms. Discontinued.

Ranked #15 of 71 in Large Size Floorstanding Speakers, last listed at $2400 - Revel F208: $2400 per pair used, Discontinued eBay

Pros: CEA2034 spinorama shows a fairly even on-axis response with sensitivity matching spec at ~87-88dB. Predicted in-room response is a smooth, textbook-quality downward slope that should translate well to most rooms without correction. Early reflections sum so cleanly with the direct sound that side-wall absorption isn’t recommended - it would work against the speaker’s naturally well-integrated off-axis behavior. Distortion stays below 0.5% from 100Hz up at 96dB/1m, with all distortion components falling below audible threshold above 200Hz. Very wide horizontal directivity of about ±75 degrees. Measured performance was judged very close to Revel’s own flagship Salon2, and Revel’s speakers (including this one) are developed using Harman’s double-blind listening test methodology. Preference score of 6.6 (7.7 with a subwoofer added). Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 88.2dB.

Cons: Some directivity error and tweeter-response ripple right at the 2.2kHz crossover point. A notable on-axis dip at about 4kHz, attributed to probable cabinet diffraction. Cumulative spectral decay (waterfall) shows an unexplained resonance around 4-5kHz that the reviewer couldn’t pin down a clear cause for. Vertical directivity shows narrowband interference nulls just above and below the tweeter axis (roughly 2-3kHz), typical of a non-coaxial tower with vertically separated drivers, so listening height matters more than it would with a coincident design. Minimum impedance dips to 3.4 ohms, calling for a robust, high-current amplifier. Distortion climbs substantially below about 80-100Hz (up to ~5% in the deep bass) when driven hard, an excursion-limited trade-off typical of towers at high output. Isolating the woofers alone shows their usable range ending around 500-700Hz at the crossover, with somewhat elevated (though still low in absolute terms) 2nd/3rd harmonic distortion in the 100-300Hz region. Discontinued.

Ranked #22 of 71 in Large Size Floorstanding Speakers, last listed at $2000 - Revel F206: $2000 per pair used, Discontinued eBay

Pros: CEA2034 spinorama shows a pretty even on-axis response. Predicted in-room response is excellent, with a smooth downward slope. Horizontal beamwidth of about ±65 degrees is wide, if a bit uneven. Distortion is very nice at 86dB SPL/1m, falling below the frequency range where human hearing is most sensitive, and stays excellent even at 96dB SPL/1m. Near-field measurements of the individual drivers show nice suppression of port and woofer resonances. Really amazing value for the performance. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 87dB.

Cons: Some directivity error and a small peak around 4.5kHz show up alongside the directivity error around 3kHz. Vertical directivity means listening position needs to stay within the tweeter axis, though the reviewer notes there is some leeway. Minimum impedance dips to 3.3 ohms, calling for an amplifier comfortable with a demanding load. Discontinued.

Small Home Subwoofers (Under 30 lbs)

Ranked #1 of 48 in Small Home Subwoofers (Under 30 lbs), last listed at $500 - SVS SB-1000: $500 Discontinued eBay

Pros: Independent CEA-2010 testing records 95.5 dB at 20 Hz and 116.3 dB through 40-80 Hz. The sealed enclosure with 12” (305mm) driver delivers substantial upper-bass output for movie effects and music.

Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 342.9H x 330.2W x 355.6D mm cabinet and 12.2 kg mass still require deliberate placement and calibration. Discontinued.

Notes: Discontinued 2021-02-25 when SB-1000 PRO was released.

Ranked #25 of 110 in Large Home Subwoofers (Over 75 lbs), last listed at $1699 - SVS PC13-Ultra: $1699 Discontinued eBay

Pros: Independent CEA-2010 testing records 114.6 dB at 20 Hz and 125.8 dB (avg of 3/4 bands) through 40-80 Hz. The ported, bottom enclosure with 13.5” (343mm) driver has the headroom for demanding film bass in a large room.

Cons: The 1168.4H x 421.6W x 421.6D mm cabinet and 40.8 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential. Discontinued.

Pros: Independent CEA-2010 testing records 102.8 dB at 20 Hz and 124.6 dB through 40-80 Hz. The ported, rear enclosure with 15” (381mm) driver delivers formidable upper-bass output for movie effects and music.

Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 508.0H x 457.2W x 508.0D mm cabinet and 72 kg mass still require deliberate placement and calibration. Discontinued.
