Large Size Powered Bookshelf Speakers
Ranked #12 of 31 in Large Size Powered Bookshelf Speakers - Buchardt A500: $4,150/pair Buchardt Audio
Pros: A sophisticated three-way active system with 450W and DSP per cabinet, using the rear 6-inch driver as a cardioid/low-bass element rather than a passive radiator. Erin found neutral balance, excellent directivity matching through the shallow waveguide, strong imaging and surprisingly deep, clean bass for the enclosure size. Downloadable master tunings can trade extension, latency and maximum SPL, while the Platin hub adds WiSA wireless, room correction and streaming. Distortion remained unobtrusive even at levels Erin considered unnecessarily loud.
Cons: Passive sensitivity is not applicable and performance depends materially on the selected DSP master, so a single response specification cannot describe every setup. The standard tuning protects the small woofers with limiting at high bass output, and ultimate headroom cannot match a large tower or a subwoofer-assisted system. Hub dependence and app/software lifecycle add failure modes absent from passive speakers; analog input is converted to DSP, and the premium price buys an ecosystem as much as drivers and cabinet.

Ranked #17 of 31 in Large Size Powered Bookshelf Speakers - Buchardt A10: $4300 Buchardtaudio
Pros: A 6.5” Purifi extended-stroke midwoofer (ultra-low distortion) crosses to a 19mm aluminum dome tweeter on an aluminum waveguide, in a two-way sealed enclosure with dedicated 150W midwoofer and 50W tweeter amplification. Nine DSP “Master Tunings,” each with a standard and “relaxed” (less bass-limited) variant, give 18 total sound signatures to try without external EQ. F3 of 30Hz and F10 of 21Hz - extends genuinely low for its size, reaching into the mid-20s Hz in-room with boundary gain, without needing a subwoofer at moderate listening levels. A true constant-directivity design: on- and off-axis response track closely aside from a treble rolloff off-axis, so EQ changes behave predictably instead of fighting a mismatched direct/reflected sound the way many speakers do. Distortion stays low, not crossing the reviewer’s 3% harmonic distortion threshold until 60-70Hz even at 96dB. Tight, focused imaging aided by DSP-driven pair matching between the two speakers.
Cons: Because it’s a constant-directivity design with a rising on-axis treble response, pointing it straight at the listener sounds noticeably bright in-room; needs about 30° of toe-out (or a high-shelf EQ cut) to sound neutral. Bass is DSP-limited at higher volumes to protect the drivers - low-end impact audibly tapers off starting around 75-80dB at 10 feet, so the deep bass that’s excellent at low-to-moderate volume thins out as you turn it up. Multitone distortion becomes an issue at the 96dB/1m target output, with about 2.5dB of compression bringing effective max output closer to 94dB/1m; a dedicated low-frequency tuning or preamp-based excursion limiting is needed for loud, sustained listening. The vertical sweet spot is fairly tight at about ±15-20° above/below the tweeter/waveguide midpoint - outside that window there’s a suckout in the upper midrange where the woofer hands off to the tweeter. Adding a subwoofer crossed in at 80Hz meaningfully reduces both distortion and compression, so pairing one in is worthwhile if you want to play loud. Premium pricing for a speaker not intended for high-volume, full-range duty - best suited to small-to-medium rooms at moderate listening levels.

Large Size Powered Floorstanding Speakers
Ranked #2 of 3 in Large Size Powered Floorstanding Speakers - Buchardt A700: $6,600 Buchardt Audio
Pros: Excellent bass extension for a cardioid-capable design, measuring F3 51Hz/F10 22Hz, with very low multitone distortion through the midrange - among the best the reviewer has measured. Selectable Master Tuning DSP profiles let you switch the speaker’s entire voicing via USB, including a cardioid bass mode that made the low end noticeably more neutral in the reviewer’s room versus the standard tuning. All-in-one powered design with 4x150W amplification per speaker (front/rear 6” woofers, 6” midwoofer, 3/4” waveguide-loaded tweeter), so no separate amp is needed. The optional Platin wireless hub adds streaming plus room EQ and manual parametric adjustment from a phone app - the reviewer strongly recommends buying it. Checks off nearly every audiophile box: great out-of-box sound, extensive tuning flexibility, and a 45-day home trial policy.
Cons: Horizontal radiation is narrower than the reviewer’s preferred ~60 degrees - closer to ±50°, giving somewhat less room involvement than he’d like. Vertical dispersion is quite narrow (about ±10°), meaning seated ear height needs to be dialed in carefully; not well suited to multi-row home theater seating. Compression starts to show at 102dB output, though it’s not severe. Genuinely expensive at roughly $6,600/pair (€6,000), and the optional Platin hub - which the reviewer considers close to essential for the best experience - adds another ~€300 on top.

Large Size Bookshelf Speakers
Ranked #16 of 84 in Large Size Bookshelf Speakers - Buchardt Audio E50: $4600 Buchardt Audio
Pros: Exceptional bass extension for a bookshelf - F3 at 40Hz, F10 at 34Hz - with genuinely low-end weight the reviewer kept noticing track after track, not just a single room-boosted note. Mid and lower-midrange are very neutral with no coloration and well-executed baffle-step compensation, so it doesn’t need to sit close to a wall like many bookshelf designs. Low distortion throughout the midrange, controlled ~60-degree horizontal directivity, and a striking driver/waveguide integration that looks genuinely upscale.
Cons: A roughly 3dB dip in the upper midrange/lower treble softens attack and dialogue clarity - the reviewer’s main complaint, and it’s baked into the crossover rather than a directivity artifact, so it’s audible both on and off axis. Sounds too bright pointed directly at the listener; needs about 10-20 degrees of toe-out to tame the treble and slightly smooth (not eliminate) that dip. Below-average sensitivity (measured 83.1dB vs 85dB spec) calls for a beefier amp, and the speaker’s tonal balance is unusually sensitive to amplifier output impedance - a poor tube amp can shift the midrange by up to 2dB.

Ranked #48 of 84 in Large Size Bookshelf Speakers - Buchardt S400 MKII: $2400 Buchardtaudio
Pros: Two-way design with a 3/4” tweeter on a well-implemented aluminum waveguide (compression-driver style, letting the small tweeter cross unusually low at 1800Hz), a 6” SB Acoustics-style mid-woofer, and a tunable 5x8” passive radiator adjustable via rear weights. Exceptionally flat on-axis linearity, within about ±2dB from 80Hz to 16kHz. Wide horizontal radiation for a waveguided design (about ±45-50°), notably broader than a comparable narrow-waveguide rival like the Klipsch Sevens (~±30°). Well-focused, precise imaging, aided by tight pair matching between the two speakers. Takes very well to EQ correction, letting listeners easily dial in the top end or add midrange fullness to taste. Bass extension reaches a genuine 50Hz in-room from a mellow, well-tuned rolloff rather than an artificially boosted one.
Cons: Sounds a bit bright and slightly boosted above about 7-8kHz on-axis, even with 30° of toe-out - benefits from about 1 inch of sidewall absorption at the first reflection points to tame it. A mild dullness noted especially on male vocals, alongside a small dip around 300-600Hz. Vertical positioning is critical and unusually “temperamental” - sitting even slightly toward the tweeter line causes a suckout, while sitting above it adds too much energy; not well suited to multi-height home theater seating. Distortion is fine at 86dB but runs into real issues by 96dB - not a high-output speaker. Some compression-related enhancement appears around 1.2kHz (crossover-region interaction), and the tweeter shows clear compression at 102dB. The woofer can bottom out at extreme low-frequency content played very loud; crossing to a subwoofer below 60Hz caused output problems at high volume, while 80-100Hz worked well. A subwoofer isn’t strictly required to protect the speaker at moderate listening levels (80-85dB at 3 meters), but is still recommended for genuine low-octave extension.

Large Size Bookshelf Speakers
Ranked #24 of 84 in Large Size Bookshelf Speakers - Buchardt Audio S400: €1,800 Discontinued Buchardt Audio
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.
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.
