Description Technical Specs Frequently Asked Questions

Audiophile performance. They blend in so well, you'll have to point them out to your friends.

Everyday TV/Surround Room
Primary Music Listening Areas
Designer Interiors

Recommended for use as left and right front channel speakers, stealth side or rear surround speakers in a ProTrim theater system setup, or for superior dynamics in practically invisible multi-zone music systems. Constructed of durable, moisture resistant materials, these speakers are safe for use in bathrooms, kitchens, saunas, or even under outdoor eaves.

Discrete, Precision-crafted, Exquisite, Accurate Sound

These speakers never attract attention by their looks, only by their performance. Practically invisible with only 4mm of grill showing, these speakers disappear gracefully for an elegant solution to either a monstrous home theater or a fluid continuation of glorious music throughout your home creating that peaceful environ to thrive and live well.


  • Resounding, intense, booming bass for that full effect action packed movie from lightweight and stiff gold Apolymer-Cones™ (Propriety coated polymerized woofer material).

  • Brilliant highs and smooth midranges in an effective diffusion pattern ideal for flat wall/ceiling installations come from pure balanced synthetic silk soft Accutec-Dome™ tweeters (Propriety designed density polymer chained formula).

  • Easy one-cut, drop-in installation puts built-in audio within reach, with Exact Fit templates and a precision flange that clamps the speaker securely to the drywall.

  • Get a lifetime of reliable sound from the durable, CAD (computer aided design) modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances.

  • Enjoy greater accuracy and more realistic imaging with aiming tweeters that pivot independently.

  • Timbre matching (the family of speakers sound the same) ensuring utterly seamless blending from speaker to speaker. They are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms with nearly transparent, ultra-small perfs

  • Practically invisible once installed with the magnetically attached exclusive wafer-thin Rarefied-Grille™

  • Visualize an even more hidden look by painting the grill and frame of the speakers for a nearly invisible installation.

"This new trim less design looks so elegant that it never
looks out of place regardless of the fancy factor of the home.
--Installer Brian Kruse

5 of 5 Just great speakers January 4, 2021
Reviewer: Dave in PDX from PORTLAND, OR United States  
I cannot begin to count the hours that I spent pouring over reviews and specs in the hunt for my in-ceiling speakers.  I found the Inwallstore approach for providing a basis for comparing like for like speaker materials and construction extremely helpful.  The speakers are fantastic - solid construction, efficient, clear and accurate; they were absolutely the right call for my system.  Throw-in the price point and they cannot be beat, not even close.  You will pay much, much more for "big name brand" speakers that approach the same construction and quality profile.  The question is: Why?  I purchased a matched set of in-wall units and I will certainly be back the next time I need speakers.

Reviewer: Mike Reale from New Smyrna Beach, FL United States  
I put in a 5.1 system with the following speakers. Fantastic speakers great sound and was very surprised. I had to sell my Infinity Primus Speakers when I moved and was not sure if I could find speakers to create that sound I was looking for but I did. Good company, great service and GREAT speakers

I purchased a combo inwall and in ceiling surrounds. They sound great, install was a breeze, and I'm sure I made the right choice.
