This page ranks 28 passive in-wall and in-ceiling speakers. Unlike a bookshelf pair, these mount flush inside a wall or ceiling cavity behind a paintable grille, so they disappear from the room instead of sitting on a stand. They have no built-in amp, so a receiver or external amplifier drives them, and they’re normally sold and priced per unit rather than per pair.
They’re a common choice for whole-home background audio, a home theater’s surround and height channels, or any room where floor space for a speaker isn’t available. Because the driver sits recessed behind drywall, installation depth, mounting cutout size, and the wall or ceiling cavity itself all affect the sound more than they would with a free-standing speaker, so check those dimensions against the space before buying.

#1 KEF Ci3160RLM-THX: $4,579.98 per pair Amazon $2,289.99 eBay
Older model: the KEF Ci3160RL-THX (ranked lower, rated 4.3/5). See every KEF Ci THX In-Wall generation.
Same family: the KEF CI250RRM-THX (smaller in-wall, ranked lower, rated 4.1/5).
Pros: Independently measured by Audio Science Review on a Klippel rig to a genuine 58.6Hz at -3dB and roughly 36Hz at -10dB, with an on-axis slope of just -0.02dB per octave, essentially flat. Directivity is the most consistent of any in-wall or in-ceiling speaker in this category, with the tightest spread in its sound-power directivity index across the measured band. The rotatable, tiltable driver module (the RLM in its name) lets the tweeter and midrange aim toward the listening area even when the cabinet itself has to be installed off to one side. THX Ultra2 certified, with a 4-driver, 3-way layout: dual 6.5” woofers flanking a 6.5” Uni-Q coaxial midrange/tweeter. Measured bass extension of 58.6Hz (-3dB).
Cons: At $2290 each, a stereo pair costs twice that, among the most expensive options in this category. Listening-window and sound-power smoothness are moderate rather than class-leading, meaning some unevenness remains once you move off the main listening axis despite the flat on-axis trace. The 660 x 209mm cutout and 106mm mounting depth are large enough that they won’t fit inside a standard 2x4 wall stud bay without modification.

#2 Revel W553L: $1,089.90 per pair Crutchfield $544.95 eBay
Pros: Erin’s Audio Corner’s Klippel measurement gives a preference score of 4.84, or 7.50 with a perfect subwoofer, a strong result for an in-wall speaker at this price. On-axis response is smooth (0.68 smoothness) and directivity is well controlled (SPDI deviation 2.35dB), so the sound off to the sides stays close to the sound you hear straight on. Bass measures to 64.5Hz at -3dB and 51.3Hz at -6dB. The 1” aluminum dome tweeter swivels toward the listening seat, a three-position switch trims treble to suit the room, and the cabinet mounts vertically or horizontally, so it works as a left, right or center channel. Measured bass extension of 64.5Hz (-3dB).
Cons: At $545 each a stereo pair costs twice that, and a separate amplifier is required. Bass ends early for a main speaker, with -3dB at 64.5Hz, so a subwoofer is needed for music and movies. Audio Science Review’s own measurement was less flattering (preference score 4.04, -3dB at 82Hz), so results differ between test benches. Two 5.25” woofers give less output headroom than the larger Revel in-wall models.

#3 Revel W126Be: $3,849.90 per pair Crutchfield $1,924.95 eBay
Same family: the Revel W226Be (larger in-wall, ranked lower, rated 4.2/5) and the Revel W228Be (larger in-wall, ranked lower, rated 4.2/5).
Pros: Revel’s own measurement, published on spinorama.org, gives a preference score of 5.39, or 7.97 with a perfect subwoofer, with a smooth predicted in-room response (0.85 smoothness). Directivity is tightly controlled (SPDI deviation 2.01dB) and on-axis deviation averages only 0.34dB. Bass measures to 62.6Hz at -6dB. It pairs a 1” beryllium dome tweeter and acoustic lens waveguide with a 6.5” aluminum cone woofer, rated at 89dB sensitivity and 105dB maximum output. Measured bass extension of 89.7Hz (-3dB).
Cons: The measurement comes from Revel, digitized from its published curves, and has no independent second test, so treat the figures as manufacturer supplied. Bass is limited, with -3dB at 89.7Hz, so a subwoofer is needed for full range sound. At $1925 each a stereo pair costs twice that, and the optional back box is sold separately. A single 6.5” woofer gives less output than the dual-woofer Revel W226Be.

#4 KEF Ci3160RL-THX: $2,800 per pair Discontinued eBay
Newer model: the KEF Ci3160RLM-THX, ranked higher, rated 4.5/5, released Nov 2023. See every KEF Ci THX In-Wall generation.
Pros: A THX Ultra2 in-wall with a Uni-Q coaxial driver (1” aluminium tweeter inside a 6.5” midrange) and two 6.5” woofers, rated at 90dB. Erin’s Audio Corner measured very consistent directivity (2.29dB directivity index deviation), a listening window within 2.4dB from 300Hz to 5kHz and bass to 51.3Hz (-3dB), for a preference score of 5.24. Measured bass extension of 51.3Hz (-3dB).
Cons: The 4 ohm load needs a capable amplifier. Replaced by the KEF Ci3160RLM-THX. Discontinued.

#5 Revel W226Be: $4,949.90 per pair Crutchfield $2,474.95 eBay
Same family: the Revel W126Be (smaller in-wall, ranked higher, rated 4.3/5) and the Revel W228Be (larger in-wall, ranked lower, rated 4.2/5).
Pros: Revel’s own measurement, published on spinorama.org, gives a preference score of 5.51, or 7.60 with a perfect subwoofer. Bass measures to 48.1Hz at -3dB and 43.7Hz at -6dB, deeper than the single-woofer Revel W126Be, and directivity is well controlled (SPDI deviation 1.95dB). Dual 6.5” aluminum cone woofers and a 1” beryllium dome tweeter behind an acoustic lens waveguide give 90dB sensitivity and a rated 110dB maximum output, and it accepts 50-200W of amplifier power. Measured bass extension of 48.1Hz (-3dB).
Cons: The measurement comes from Revel, digitized from its published curves, and has no independent second test, so treat the figures as manufacturer supplied. At $2475 each a stereo pair costs twice that, and the back box is not included and is sold separately. Predicted in-room smoothness (0.81) and on-axis deviation (0.33dB) are good but not ahead of the cheaper Revel W126Be, so the extra cost buys bass and output rather than a cleaner midrange.

#6 Revel W228Be: $7,699.90 per pair Crutchfield $3,849.95 eBay
Same family: the Revel W126Be (smaller in-wall, ranked higher, rated 4.3/5) and the Revel W226Be (smaller in-wall, ranked higher, rated 4.2/5).
Pros: Revel’s own measurement, published on spinorama.org, gives a preference score of 6.79, or 8.33 with a perfect subwoofer. Bass measures to 43.4Hz at -3dB and 34.3Hz at -6dB, exceptional for an in-wall, and predicted in-room response is very smooth (0.91 smoothness) with tightly controlled directivity (SPDI deviation 1.89dB). Its three-way design uses dual 8” aluminum woofers, a 5.25” midrange and a 1” beryllium tweeter, rated for 115dB output, and the midrange and tweeter module rotates for vertical or horizontal mounting. Measured bass extension of 43.4Hz (-3dB).
Cons: Audio Science Review’s independent Klippel measurement was far weaker than Revel’s own (preference score 2.31, or 6.15 with a subwoofer, and -3dB at 108Hz), so real bass depends heavily on the installation and enclosure. The Revel figures are manufacturer supplied and digitized. At $3850 each a stereo pair costs twice that, and the speaker is about 939mm tall and 14.3kg with a 27 to 54 liter enclosure requirement, with the back box sold separately.

#7 KEF CI250RRM-THX: $5,978 per pair Amazon $2,989.00 Abt Electronics $2,999.99 eBay
Same family: the KEF Ci3160RLM-THX (larger in-wall, ranked higher, rated 4.5/5). See every KEF Ci THX In-Wall generation.
Pros: Independently measured by Audio Science Review to a genuine 51.3Hz at -3dB and roughly 23.3Hz at -10dB, the deepest bass extension of any in-wall or in-ceiling speaker in this category. It’s a THX-certified 3-way coaxial design, a 10” woofer built around a 4” Uni-Q midrange and 1” aluminum dome tweeter, deliberately voiced for the 30-60 degree off-axis angle typical of a ceiling-mounted Dolby Atmos height or surround channel rather than a straight-down listening position. Run through a receiver’s automated room correction, spinorama’s EQ-adjusted figures show its preference score climbing from 4.67 to 5.68, so it responds well to correction. Measured bass extension of 51.3Hz (-3dB).
Cons: At $2989 each, this is the most expensive speaker in this category. Its raw on-axis measurement trails the KEF Ci3160RLM-THX (preference score 4.67 vs. 4.62) since the driver array is tuned for off-axis dispersion rather than a flat straight-ahead response, and its on-axis deviation averages 1.14dB, one of the roughest of the batch measured on-axis.

#8 Monolith THX-365IW: $999.98 per pair Amazon $499.99 Monoprice $499.99 eBay
Same family: the Monolith THX-365T (floorstanding, rated 3.9/5), the Monolith THX-365C (center, rated 4.1/5) and the Monolith THX-LCR (larger in-wall, ranked lower, estimated 3.9/5).
Pros: Audio Science Review’s retest measured a preference score of 5.23, or 7.64 with a perfect subwoofer, with -3dB at 54.6Hz and -6dB at 42.8Hz, deep bass for an in-wall speaker. Directivity is well controlled (SPDI deviation 2.09dB) and on-axis smoothness is 0.70. It is a THX Ultra certified three-way, with two 6.5” woofers, a dedicated 2” silk dome midrange and a 1” silk dome tweeter, rated at 89.5dB sensitivity, which ASR’s measurement confirmed at 89.4dB. The 5-year warranty is longer than most in-wall speakers get. Measured bass extension of 54.6Hz (-3dB).
Cons: ASR’s first measurement of this speaker scored far lower (preference score 1.33, or 5.10 with a subwoofer, with -3dB at 108Hz), so results depend heavily on how it is installed and enclosed. Monoprice positions it for rear and surround channels and suggests in-room speakers up front, and the ASR reviewer said he would pick something better for a front left or right. Impedance dips to about 2.9 ohms, so the amplifier needs to be comfortable with a low load. At $500 each a stereo pair costs twice that.

#10 JBL Synthesis SCL-6: $3,629.90 per pair Audio Advice $1,814.95 eBay
Same family: the JBL Synthesis SCL-4 (smaller in-wall, ranked lower, rated 3.6/5), the JBL Synthesis SCL-3 (larger in-wall, ranked lower, rated 3.7/5), the JBL Synthesis SCL-7 (larger in-wall, ranked lower, rated 3.7/5), the JBL Synthesis SCL-1 (larger in-wall, ranked lower, rated 3.7/5) and the JBL Synthesis SCL-5 (larger in-wall, ranked lower, rated 2.5/5).
Pros: Erin’s Audio Corner measured it with a very tight 1.2dB reference band and 0.67 listening-window smoothness, and its preference score rises from 3.92 to 6.71 with a subwoofer. Four 5.25-inch aluminum woofers around a 2410H-2 compression driver on JBL’s imaging horn give 91dB sensitivity and high output, with an 80 degree by 80 degree treble coverage pattern that keeps directivity consistent. Bass measures 67.4Hz at -3dB and about 40.8Hz at -10dB in free air, before the extra wall reinforcement of an in-wall install. Measured bass extension of 67.4Hz (-3dB).
Cons: Bass is limited without a subwoofer, and a 3.92 standard score trails the best in-wall speakers here. Average on-axis deviation of 0.49dB is rougher than the Revel in-walls. The 4 ohm load and 766mm tall cutout need a capable amplifier and a tall wall cavity, and at $1815 each it is sold mainly through custom-installation dealers.

#11 Monolith THX-LCR Discontinued eBay
Same family: the Monolith THX-365T (floorstanding, rated 3.9/5), the Monolith THX-365C (center, rated 4.1/5) and the Monolith THX-365IW (smaller in-wall, ranked higher, rated 4/5).
Pros: A three-way THX Ultra in-wall LCR with two 6.5” woofers, a 2” silk dome midrange and a 1” silk tweeter, rated at 88.5dB. A review found strong dynamics, wide off-axis response and a neutral tone.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. The review measured bass to about 65Hz in a wall, and its 14.4” width is awkward for 16” stud bays. It is discontinued.

#12 KEF CI200RR-THX: $2,399.98 per pair Amazon $1,199.99 eBay
Pros: An 8” woofer paired with a 1.5” Uni-Q tweeter (crossing over at 2.2kHz) measures a genuine 82.5Hz at -3dB and roughly 30.5Hz at -10dB, respectable low-end reach for a mid-priced in-ceiling speaker. The 238mm cutout accepts a large enough driver to move real air in a family room or media room. At $1200 each, it costs about half of the flagship KEF Ci3160RLM-THX while carrying the same THX certification. Measured bass extension of 82.5Hz (-3dB).
Cons: Spinorama’s measurement of this model is a lower-confidence manufacturer curve rather than an independently verified Klippel scan, so treat the extension figures as directionally useful rather than as precise as the ASR-measured entries in this category. No Harman-style preference score has been published for it.

#13 JBL Synthesis SCL-3: $7,259.90 per pair Audio Advice $3,629.95 eBay
Same family: the JBL Synthesis SCL-4 (smaller in-wall, ranked lower, rated 3.6/5), the JBL Synthesis SCL-6 (smaller in-wall, ranked higher, rated 3.9/5), the JBL Synthesis SCL-7 (larger in-wall, ranked lower, rated 3.7/5), the JBL Synthesis SCL-1 (larger in-wall, ranked lower, rated 3.7/5) and the JBL Synthesis SCL-5 (larger in-wall, ranked lower, rated 2.5/5).
Pros: JBL’s own measurements show 0.32dB average on-axis deviation and a 2.28 directivity-index deviation, and the preference score rises from 3.80 to 6.42 with a subwoofer. Two 5.25-inch aluminum woofers and a 2409H compression driver on JBL’s imaging horn give 91dB sensitivity, and the square baffle works in walls or ceilings. Bi-wire and bi-amp terminals and a paintable magnetic grille suit custom home theaters. Measured bass extension of 72.4Hz (-3dB).
Cons: Bass rolls off early, at 72.4Hz for -3dB and about 45.8Hz for -10dB in free air, so it needs a subwoofer. Listening-window smoothness is only 0.43 inside a 3.1dB reference band, rougher than the other JBL Synthesis in-walls. The data is manufacturer supplied and digitized from graphs. At $3630 each it costs twice as much as the better-measuring JBL Synthesis SCL-6.

#14 JBL Synthesis SCL-7: $2,419.90 per pair Audio Advice $1,209.95 eBay
Same family: the JBL Synthesis SCL-4 (smaller in-wall, ranked lower, rated 3.6/5), the JBL Synthesis SCL-6 (smaller in-wall, ranked higher, rated 3.9/5), the JBL Synthesis SCL-3 (smaller in-wall, ranked higher, rated 3.7/5), the JBL Synthesis SCL-1 (larger in-wall, ranked lower, rated 3.7/5) and the JBL Synthesis SCL-5 (larger in-wall, ranked lower, rated 2.5/5).
Pros: Audio Science Review measured a 1.88 directivity-index deviation, among the most consistent off-axis behavior of the JBL Synthesis in-walls, and 0.60 listening-window smoothness. The preference score rises from 3.46 to 6.21 with a subwoofer. Two 5.25-inch aluminum woofers and a 2410H-2 compression driver on JBL’s imaging horn give bass to 67.4Hz at -3dB and about 42.3Hz at -10dB in free air, and at $1210 each it is the least expensive way into the JBL Synthesis in-wall range. Measured bass extension of 67.4Hz (-3dB).
Cons: The response sits in a wide 4.1dB reference band with 0.43dB average on-axis deviation, so tonal balance is less even than the JBL Synthesis SCL-6. The 3.46 standard score is low without a subwoofer. At 88dB it is 3dB less sensitive than its siblings, and the 4 ohm load needs a capable amplifier.

#15 JBL Synthesis SCL-1: $36,299.90 per pair Audio Advice $18,149.95 eBay
Same family: the JBL Synthesis SCL-4 (smaller in-wall, ranked lower, rated 3.6/5), the JBL Synthesis SCL-6 (smaller in-wall, ranked higher, rated 3.9/5), the JBL Synthesis SCL-3 (smaller in-wall, ranked higher, rated 3.7/5), the JBL Synthesis SCL-7 (smaller in-wall, ranked higher, rated 3.7/5) and the JBL Synthesis SCL-5 (larger in-wall, ranked lower, rated 2.5/5).
Pros: JBL Synthesis’s flagship in-wall left, center and right speaker with two 12” woofers and a D2 dual-diaphragm compression driver on a large HDI horn. Sensitivity is very high at 94dB, and JBL rates it to 133dB peak. JBL’s measurements show a preference score of 4.03 that reaches 6.35 with an ideal subwoofer, with 0.39 listening window deviation.
Cons: It needs a large wall cavity and at least 500W of amplification, and it is sold through JBL Synthesis custom installers. Bass reaches 53.0Hz (-3dB) and about 46Hz (-10dB).

Pros: JBL’s own measurements show a 1.85 directivity-index deviation, the most even directivity of the JBL Synthesis in-walls, with 0.35dB average on-axis deviation. The preference score rises from 3.56 to 6.55 with a subwoofer. A 7-inch aluminum woofer and 2409H compression driver on JBL’s imaging horn give 91dB sensitivity, and bi-wire and bi-amp terminals suit custom home theaters. Measured bass extension of 83.7Hz (-3dB).
Cons: Bass is the weakest here, at 83.7Hz for -3dB and about 61.9Hz for -10dB in free air, so it needs a subwoofer. Listening-window smoothness is 0.59 inside a 3.1dB reference band, and the data is manufacturer supplied and digitized from graphs.

#17 Miller & Kreisel IW150: $4,998 per pair Audiolab (authorized M&K dealer) $2,499 eBay
Pros: Erin’s Audio Corner’s Klippel measurement shows well controlled directivity (SPDI deviation 2.43dB) and a smooth predicted in-room response, with a preference score of 2.88, or 6.32 with a perfect subwoofer. The unusual layout puts two 5.25” polypropylene woofers beside a column of three 1” soft dome tweeters, a design meant to give even coverage across a room from a single wall opening. It is rated at 90dB sensitivity, and Erin’s measurement computed a real 88.2dB, and it accepts 25-400W of amplifier power. Measured bass extension of 95.2Hz (-3dB).
Cons: Bass is thin: measured -3dB is 95.2Hz and -6dB is 82.0Hz, and Miller & Kreisel rates it only to 80Hz, so a subwoofer is required, and even with a perfect subwoofer the score reaches only 6.32. On-axis smoothness is 0.48 and on-axis deviation averages 0.62dB, so the midrange is rougher than the better in-wall designs. At $2499 each a stereo pair costs twice that. Erin describes it as discontinued from what he can tell, so stock may be limited to remaining inventory.

#18 KEF CI130.2CR: $599.98 per pair World Wide Stereo $299.99 eBay
Pros: A compact 158 x 158mm cutout and 82.3mm depth fit tight joist bays and shallow ceiling cavities where the larger Ci-THX models in this category won’t. At $300 each it’s the most affordable speaker in this category by a wide margin. The 5.25” Uni-Q driver keeps its 16mm aluminum dome tweeter coaxially centered on the woofer, so the two acoustic centers stay aligned regardless of listening position. Measured bass extension of 100Hz (-3dB).
Cons: KEF’s own frequency response spec bottoms out at 52Hz, and the measured curve reaches only about 100Hz at -3dB and roughly 53.5Hz at -10dB, the shallowest low end among the models in this category with a THX certification, so pairing it with a subwoofer is worth planning for. It’s open-backed with only medium-quality vendor measurement data behind it, not an independently verified Klippel scan.

#19 Revel W990: $4,239.90 per pair Crutchfield $2,119.95 eBay
Pros: Audio Science Review’s Klippel measurement shows some of the deepest bass of any in-wall speaker, with -3dB at 32.2Hz and -6dB at 27.8Hz, so it can carry music without a subwoofer better than most. Directivity is well controlled (SPDI deviation 1.95dB). It is a three-way with a 9” woofer, a 3.5” midrange and a 1” aluminum dome tweeter, accepts 10-200W of amplifier power, and offers high frequency level, tilt, boundary compensation and listener axis controls to tune it to the room. Measured bass extension of 32.2Hz (-3dB), with a measured sensitivity of 85.9dB.
Cons: Its measured preference score is only 3.6, or 5.09 with a perfect subwoofer, because the midrange is uneven: on-axis deviation is high (0.86 normalized deviation on axis, 0.69 in the listening window) and on-axis smoothness is just 0.34. ASR’s computed sensitivity is about 85.9dB, so it needs more amplifier power than most speakers to play loud. At $2120 each a stereo pair costs twice that, which is a high price for the measured performance.

#20 Grimani Systems Rixos-L: $16,400 per pair Grimani Systems $8,200 eBay
Pros: Directivity is well controlled (SPDI deviation 1.77dB), with a rated 100 degree by 150 degree coverage pattern that keeps the sound even across a wide seating area. Two 8” woofers and a 1” compression driver on a waveguide are rated at 96dB sensitivity with output up to 117dB at 1 meter, and 600W of supplied DSP amplification with room correction over Ethernet lets an installer tune it precisely. It mounts in the wall or on the wall, including behind an acoustically transparent screen, and is made in the USA with a 2 year warranty. Measured bass extension of 87.9Hz (-3dB).
Cons: Audio Science Review measured a preference score of only 2.16, or 5.53 with a perfect subwoofer, because on-axis response is uneven (0.64 smoothness, 0.55dB average deviation). Bass measured -3dB at 87.9Hz, so a subwoofer is required. ASR also heard tweeter hiss at 2 to 3 feet, which matters for close listening. At $8200 each a stereo pair costs twice that, it needs the supplied rack amplifier and network setup, and it is sold through custom installation dealers.

#23 MartinLogan Tribute 5XW: $6,999.98 per pair Audio Advice $3,499.99 eBay
Pros: Erin’s Audio Corner’s Klippel measurement shows a rated 94dB sensitivity that measured a still efficient 88.1dB at 1 meter, so it plays loudly for its size. The folded thin-film Folded Motion XT Obsidian tweeter rotates for horizontal or vertical mounting, and it pairs two carbon fiber woofers with two 6.5” passive radiators in a sealed box. It accepts 20-250W of amplifier power and mounts with a slim 3.8” depth behind the wall. Measured bass extension of 74.7Hz (-3dB), with a measured sensitivity of 94dB.
Cons: The measurement is the weakest of the in-wall speakers here: a preference score of 1.84, or just 4.91 with a perfect subwoofer, with on-axis smoothness of 0.30, an average on-axis deviation of 1.56dB and wide directivity swings (SPDI deviation 3.25dB). Bass measured -3dB at only 74.7Hz, so a subwoofer is required, and MartinLogan rates it to 71Hz. At $3500 each a stereo pair costs twice that and MartinLogan sells it through dealers.

#24 Bowers & Wilkins CWM 7.5 S2: $2,700 per pair Audio Advice $1,350.00 eBay
Older model: the Bowers & Wilkins CWM7.5 (ranked lower, rated 2.6/5). See every Bowers & Wilkins CWM In-Wall generation.
Same family: the Bowers & Wilkins CWM7.3 S2 (larger in-wall, ranked higher, rated 3.3/5).
Pros: A Reference Series in-wall with a 1” Carbon Dome tweeter and a 5” Continuum cone, a forward-firing Flowport and a retrofittable integrated back box, rated 45Hz to 28kHz. Mounting depth is only 4 1/16”.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from its measured predecessor. Its predecessor measured poorly on axis, so the range is wide. Sensitivity is 86dB.

#25 KEF CI50R Discontinued eBay
Pros: At just 80 x 80mm and 55mm deep, this is by far the smallest speaker in this category, small enough to fit into spaces, tight closets, cabinetry, shallow ceiling cavities, that none of the other in-wall or in-ceiling models here can reach. Measured bass extension of 170Hz (-3dB).
Cons: No longer sold as a current KEF product; dealer listings mark it a legacy item replaced in KEF’s lineup, so buying one now means used or leftover new-old stock rather than a current retail purchase. It measures the shallowest bass extension of any speaker in this category by a wide margin, reaching only about 170Hz at -3dB and roughly 113Hz at -10dB, consistent with a small background or ambient-audio speaker rather than one built for full-range listening.

#26 Bowers & Wilkins CWM7.5: $1,600 per pair Discontinued eBay
Newer model: the Bowers & Wilkins CWM 7.5 S2, ranked higher, estimated 3/5, released 2019. See every Bowers & Wilkins CWM In-Wall generation.
Pros: A two-way in-wall speaker with a 5” mid/bass driver, a 1” tweeter and an integrated back box, so it does not depend on the wall cavity. The only Spinorama data shows very consistent directivity (2.49dB directivity index deviation) and bass to about 59Hz (-10dB). Measured bass extension of 69.0Hz (-3dB).
Cons: That data is low quality and shows a very uneven on-axis response (1.99dB average deviation) and a rough predicted in-room response (0.17), for a preference score of 1.63. Replaced by the Bowers & Wilkins CWM 7.5 S2. Discontinued.

#27 JBL Synthesis SCL-5: $4,400 per pair eBay
Same family: the JBL Synthesis SCL-4 (smaller in-wall, ranked higher, rated 3.6/5), the JBL Synthesis SCL-6 (smaller in-wall, ranked higher, rated 3.9/5), the JBL Synthesis SCL-3 (smaller in-wall, ranked higher, rated 3.7/5), the JBL Synthesis SCL-7 (smaller in-wall, ranked higher, rated 3.7/5) and the JBL Synthesis SCL-1 (smaller in-wall, ranked higher, rated 3.7/5).
Pros: A round in-ceiling speaker from JBL Synthesis with a waveguide-loaded tweeter, made to match the SCL in-wall range. Audio Science Review measured a preference score of 0.43 that reaches 3.31 with an ideal subwoofer, with 1.00 listening window deviation. Measured bass extension of 74.7Hz (-3dB).
Cons: Bass is limited and the in-room balance is uneven, for a low standalone preference score. It is sold through JBL Synthesis custom installers. Bass reaches 74.7Hz (-3dB) and about 34Hz (-10dB).

#28 SpeakerCraft AIM8 One eBay
Pros: An in-ceiling speaker from SpeakerCraft’s AIM line with an 8” woofer and a pivoting tweeter that can be aimed toward the listening position. Measurements show a preference score of -1.5 that reaches 0.55 with an ideal subwoofer, with 1.41 listening window deviation. Measured bass extension of 60.5Hz (-3dB).
Cons: The response is very uneven, for a preference score of -1.50 that reaches only 0.55 with an ideal subwoofer, and that data is low quality. Bass reaches 60.5Hz (-3dB) and about 22Hz (-10dB). That data is low quality.
