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.

Whether you're savouring your favourite music or movie, the slender twenty5.sub, with its elegant Diamond Black finish, fits discreetly into any room and completes the audiophile experience.
This combination of active electronics from PMC's renowned professional systems, our 400W Class-D ultra-low-distortion amplifiers, proprietary ATL™ and new Laminair™ technologies, and potent 6.5-inch high-excursion bass units, can faithfully reproduce frequencies down to 22Hz, and handle dynamic contrasts from the sonic complexity of a Hollywood blockbuster soundtrack to the filigree detail in a chamber music solo, with maximum resolution and precision-timed bass.
For the finishing touches, intuitive user control over EQ and filters allows for perfect integration of the sub with its listening environment — and with accompanying loudspeakers, because the twenty5.sub also makes an excellent addition to stereo setups.
Partnered with the compact twenty5.21 or 22 speakers, the sub forms a powerful system; the twenty5.sub handles the low frequencies, leaving the left and right speakers to concentrate on the mid-range. The result is performance close to that of the three-way twenty5.26, but in a more discreet package.

Wilson Audio
Subsonic
41000
/
Released
The Wilson Audio Subsonic is the fraternal twin of the WAMM Master Subsonic. It features the same subwoofer drivers and the same internal volume. The differences lie in the finish details. The metal work in the WAMM Master Subsonic features the prismatic finish that mirrors (no pun intended) the WAMM's main array gantry. On the Wilson Audio Subsonic, the metal work is from Wilson's main line finish process—the same level of metal finish that has adorned Wilson products throughout the line.
Wilson Audio is often considered the quintessential American high-end hi-fi brand, a staple in premium audio dealerships across the country. Many reviewers use Wilson speakers in their own home systems, reflecting their reputation for outstanding dynamics, bass depth, and the ability to reproduce classical music with remarkable realism. Wilson focuses on creating an uncolored sound, aiming to replicate the experience of live, unamplified performances.

Our Summary
Product Strengths
- Subsonics allow the listener to not only hear the bass, but also to feel it, making the experience more immersive and powerful
- Measurements showed very flat, very smooth response, plus or minus maybe 1 dB using pink noise
- The blend is beautiful
Product Considerations
- Each subwoofer is $41,000 US, the crossover is another $5,500, and an amplifier is also needed
Takeaway: The subsonics offer a unique and immersive listening experience, allowing one to not only hear, but also feel the music, making it more powerful and realistic. If one wants the best sound and has the budget, the subsonics could be a great choice.
