What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

The ci series The ci series are ideal for playback of stereo and immersive formats, and the largest models provide the greatest headroom, bass and dynamics. All models apart from the ci140 and ci140sub may be mounted in- or on-wall, thanks to their Qikfire™ fittings, bezel-less grille and stylish cabinet sleeve.

In-wall mounting The Qikfire™ in-wall mounting system makes the range very "installer-friendly". The ci30, ci45, ci90slim andci65 are fitted with Qikfire, a spring-loaded mounting system which allows the loudspeaker to be fixed in position with a simple twist of a screwdriver. Removal is just as easy as installation, with a simple twist.

On-wall mounting On-wall mounting is just as straightforward as in-wall mounting, using the supplied interlocking bracket, which is designed to also offer pin-point level adjustment. For the ci30, ci45, ci90slim andci65 an optional mounting sleeve in white or black may be fitted around the cabinets to conceal the in-wall mounting system creating an elegant and discrete on-wall loudspeaker.

Wisdom Audio
Insight Series P4i

Reviews

Compact in size, the Insight Series P4i defies traditional categorization. Sharing the design elements of its larger Insight Series sibling, it is hard to believe the musical and cinematic performance and dynamic quality of this small in-wall loudspeaker. The Insight Series P4i includes a planar magnetic driver – and four robust 3”x5” woofers for low distortion, high-resolution sound, and a superior dynamic range. The result is excellent, uniform horizontal dispersion throughout its operating range, providing superb off-axis coverage in both in-wall and in-ceiling applications.

Wisdom Audio specializes in planar magnetic drivers and line source speaker technology, which provides consistent sound coverage throughout a room and minimizes sound distortion compared to traditional point source speakers. Their speakers are designed to be integrated into walls or ceilings without compromising sound quality.

Product Strengths

  • Truly outstanding sound quality, delivering a near-electrostatic, audiophile listening experience in a disappearing, in-wall package
  • Uses planar magnetic thin-film drivers (PMD) which can be highly detailed with excellent transient response
  • PMDs are quite reliable because the spread-out "voice grid" is great at dissipating heat
  • PMDs are super-easy for an amplifier to drive, as they are "an almost perfectly resistive load"

Product Considerations

  • Horizontal center channel use of the Insight P4i requires stud modifications due to its size

Comparisons (according to reviewers)

  • The Insight series squeezes most of the sound quality of the Wisdom Audio Sage Series into a less imposing, less costly package

Takeaway: The Wisdom Audio Insight P4i speakers provide excellent sound quality in an in-wall design, and are a great way to get high-end audio without large, free-standing speakers. They could be worth buying for those who want the best possible sound without compromising on interior design.

Focal
300 IWLCR 6
1199
/
Released
Discreetly positioned both horizontally and vertically, this LCR (left, center, right) loudspeaker offers a pure Home Cinema experience, just as it ideally complements a classic floorstanding or bookshelf speaker system. Among its strengths: exclusive Focal technologies for hi-fi sound, discreet, easy installation, and an adjustable turntable that targets the listening point.
Check Amazon
Focal is a French hifi brand that makes their own drivers in-house, including their highly-regarded beryllium tweeters and unique slatefiber mid/bass drivers made from recycled carbon fiber. Their speakers and headphones feature distinctive technologies like their "W" sandwich cone design for optimal driver performance and Mimi Sound Personalization that adapts audio to individual hearing profiles.
Expand Details

Our Summary

Product Strengths

  • Tool-less design with the Easy Quick Install (EQI) system allows for quick and easy installation
  • Flax cone drivers offer light, stiff cones with good natural damping
  • The design allows for both horizontal and vertical installation by rotating the high-frequency/mid-range pod
  • Delivers impressive dynamics, a clean, neutral balance, and articulate dialogue handling
  • Easy to drive with an amplifier

Product Considerations

  • The Easy Quick Install (EQI) system may not work in all situations due to space constraints behind the wall
  • The open-back design can make the speaker's balance dependent on the installation environment, potentially requiring EQ adjustments
  • Adding the included black acoustic cloth to the grille darkens the overall color shade, which is not ideal for color matching applications
  • If a clamp breaks on the tool-less design, it is not easily replaceable
  • Requires more horizontal spacing than speakers with traditional dogears, requiring installers to be more careful about between-stud placement

Comparisons (according to reviewers)

  • Vs Focal Kanta No. 2: The Kanta No. 2 has a weightier midrange, superlative upper frequencies, more depth, wider soundstage, and improved imaging, though the 300IWLCR6's sound quality is satisfying
  • Vs PSB W-LCR: The PSB exhibits a very slight nasal characteristic, which is not noticed on the Focal LCRs
  • Vs Martin Logan Axis: The Martin Logan Axis has impressive imaging and upper-end frequency output due to its folded ribbon tweeter, which is very different from the Focals' inverted dome aluminum and magnesium tweeter

Takeaway: The Focal 300IWLCR6 in-wall loudspeaker is easy to install and delivers great sound for music and movies, especially when paired with a good subwoofer. The speaker can be easily installed, and it can fit into various home theater setups.

M&K Sound
IW150A
1599
/
Released
2022
The IW150A is a versatile in-wall/in-ceiling speaker, designed for the ultimate home theater experience. Targeted primarily as a Dolby Atmos-friendly in-ceiling model, it can also be used for other in-wall cinema or multi-room music applications. Its single 15-degree angle-fixed tweeter makes the IW150A ideal for effects-based sound in multi-speaker setups.

M&K Sound invented the world's first subwoofer in 1973 and is widely used in Hollywood studios for mixing and mastering film soundtracks. Their push-pull subwoofer design cancels out harmonic distortion, and their speakers deliver professional studio monitor neutrality, making them a top choice for high-end audio production.
Expand Details

Our Summary

Product Strengths

  • Retains the neutrality, realism, and musicality associated with the M&K Sound design in a discreet enclosure
  • The front three IW150 models perfectly match each other in terms of tonality and are utterly transparent
  • Capable of a pleasingly open sound that fills the room with wonderful detail and clarity
  • The transient response of these speakers is incredible, viscerally delivering the scares as the soundtrack suddenly goes from relative silence to very loud

Product Considerations

  • Slightly lacking at the low-end, designed to be used with a subwoofer
  • Placement can be non-trivial and orientation moreso because of the multi-woofer/tweeter design, resulting in a weird dispersion that will sound different depending on which side of the speaker one is on
  • Putting them in the wall might change its sonic integrity

Comparisons (according to reviewers)

  • IW150 is an in-wall version of the M&K Sound S150

Takeaway: The IW150 delivers the detail, clarity, and transience of a professional studio monitor from a discreet, in-wall enclosure. If one is looking for in-wall speakers that vanish into their decor, then these are worth an audition.
