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.

D stands for discreet – all models are designed as installation speakers for discreet in-wall or in-ceiling integration, featuring a wall-fixing mechanism with mounting legs. All models also come with their own loudspeaker enclosure, making system planning and the actual installation as easy as possible, with no after-market backbox or closed wall cavity required. This also ensures that the sound performance is always defined and consistent, depending less on the wall construction and the available space behind the wall.

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

  • The brand's digital amplifiers, underpinned by proprietary Equibit technology, minimize signal conversion for a cleaner, more direct signal path to the speakers.
  • RoomPerfect technology allows Lyngdorf systems to analyze and adapt to the unique acoustic properties of any listening space, optimizing the sound for a more immersive experience.

MH-3

  • Positioning: The entry-level speaker is compact, ideal for small stereo or media room installations.
  • Description: Features a compact design, making it perfect for small spaces while still delivering dynamic performance. Uses a powerful 4-inch midrange driver with a magnet 50% stronger than traditional drivers, offering higher sensitivity and a linear frequency response. Compared to the FR-2 and Cue-100, it's more affordable and compact, making it suitable for those with limited space and budget, but lacks the advanced technologies and larger soundstage of the higher-end models.

FR-2

  • Positioning: A mid-range floor-standing speaker designed for optimal wall placement.
  • Description: Features a shallow cabinet design and high-performance woofers, providing tight and powerful bass when placed against a wall. Uses a downward-facing bass reflex port for consistent acoustic performance. While it offers better bass response than the MH-3, it doesn't match the Cue-100's advanced driver technology and customization options.

Cue-100

  • Positioning: A high-end standmount loudspeaker aimed at audiophiles and design-conscious users.
  • Description: Features Purifi USHINDI technology, which delivers ultra-low distortion and high sound purity. Its unique triangular design and customizable fabric covers offer both aesthetic appeal and acoustic excellence. Compared to the MH-3 and FR-2, provides superior sound quality and design flexibility.

Our take on the brand

Lyngdorf Audio is known for its RoomPerfect technology, which learns and corrects room acoustics, and for creating the first fully digital amplifier that converts digital signals directly to PWM without a traditional DAC. The brand's unique Boundary Woofers are designed to be placed against walls to use room acoustics for better bass, setting them apart from traditional subwoofer approaches.

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

Our own amplifier technology sets our TDAI streaming amps apart. It is a so-called digital amplification which amplifies digital audio directly, without the common analogue conversions, signal paths, and side effects within the unit. We also have a unique, absolutely lossless way of volume control, whereas in most amplifiers the incoming music signal is attenuated.

Our second key innovation is RoomPerfect, available in our stereo and home cinema products. This calibration measures and addresses room acoustical issues, which affect even the best listening rooms, yet without linearizing and neutralizing the sound too much.

What's your approach to customer support?

Every Lyngdorf dealer can be contacted no matter where one bought the product, but we are proud to also offer direct support by our team here at the headquarters in Denmark. They have direct access to all Lyngdorf products in our demo and test rooms. Furthermore, a Backup function in our amplifiers and processors allows us to mirror customer settings remotely on our device, so we can literally look into it and give better advice — for example, for setting up or finding faults along the audio chain.

Last but not least, we can offer support and repairs even for the first Lyngdorf products made here decades ago, which includes a 24-hour burn-in test — not only to verify functions but to measure the performance-relevant specs. [email protected]

What are your favorite tracks for showcasing the strength of your products?

Three? You mean three hundred?

Odetta – Hit or Miss. This is an old but excellent recording from 1970. It requires a good system and room to make it sound realistic and alive. Listen for well-separated instruments, good timing, and a tuneful bass. Everything is alright production-wise, so any shortcomings rather come from the listening room and audio system.

Vestbo Trio – Italian Movie, Portuguese Wine. This is a reference for capturing the sound and dynamics of real instruments in a good recording studio. No compression or autotune involved. Listen for the space, soundstage, and realism as the song shifts up one gear. You should almost have the guys playing in your room.

Gidge – Quasar. Electronic music can be quite challenging because there are no microphones as a filter. Someone with a computer and synthesizer can just go crazy, and the audio system has to cope. This Swedish duo will test the limits of your speakers. Listen whether it sounds powerful yet pure and defined at the same time. This kind of music is rather done for clubs, so it requires good speakers, speaker placement, and ideally some degree of calibration to control the energy in a normal living room.

What other products pair best with yours?

One great advantage of our room calibration RoomPerfect is that it doesn't do what many other calibrations do — linearizing and neutralizing the sound, and therefore linearizing the characteristic sound of someone's chosen loudspeaker. What many Lyngdorf owners, dealers, and reviewers like about RoomPerfect is that it preserves what the speaker is good at, so there's real synergy here. No matter whether someone prefers a Dali, Bowers & Wilkins, Dynaudio, Sonus Faber, Spendor, or any other. Our amplifiers also have no problem driving low-impedance speakers, so really not much to worry about regarding system matching. The biggest challenge is the listening room.

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.

Expand Details

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.
Check Amazon
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.
