What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- As part of the M&K Sound system, the S150T uses the same drivers as the S150, allowing for seamless panning of sounds around the room
- The S150T's Tripole design offers both direct and diffused sound, blending directional accuracy with a spacious soundscape
- The Tripole design of the S150T helps it to 'disappear into the room' and become part of a cohesive 360-degree soundscape
- The S150T's design makes it suitable for use in Atmos setups, preferred by some over monopole surround speakers
Product Considerations
- The S150T needs to be flush-mounted to the wall, as it lacks a mounting hole for a speaker bracket

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.

Description
Side- or rear-mounted speakers in a multi-channel audio system pose a radically different set of performance challenges relative to conventional stereo systems, because surround speakers are typically positioned much closer to the listener and deliver sound to the ears from very different angles. The proprietary M&K Sound Tripole® configuration, essentially two speakers mounted in a single cabinet, is the first and only technology to effectively address these major issues to deliver both image specificity and an enveloping surround field, without compromise.

- They create an incredibly large, deep soundstage that will fill the room and place within that soundstage images as clear and precise as any speaker
- They handle pretty much every other aspect of what a speaker should do in an exemplary fashion
- Very easy to drive
Product Considerations
- These proved to be the most time consuming speakers to position that one has ever had in one's rooms
- Toe-in angle was critical, distance from the wall behind them was super critical, and all totally room dependent
- These are very directional speakers
- The bass response has to be looked at in conjunction with the room one is using them in
- They also require a relatively long 100 hour "break-in" period before they really start to loosen up a little and really shine
Comparisons (according to reviewers)
- Vs Tekton Lore, they do everything better than the Lores
Takeaway: The Double Impact is a stunning achievement in speaker design that offers an immersive and detailed listening experience. If one appreciates natural sound, exceptional detail, and a wide soundstage, these speakers are definitely worth considering for an audio setup.

Wisdom Audio
Insight Series P4i
2760
/
Released
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.
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
Our Summary
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.
