  • Exceptional low end fidelity for the most intense musical or theatrical pieces created by Provlar™ woofers. Our improved version of Kevlar, introduced in 2010.

  • 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.

5 of 5 Great products, excellent pricing, amazing support March 22, 2018
Reviewer: SS from San Diego, CA United States  
Having been an audiophile for decades (previously moving in the Wilson, Pass, Theta, Krell, Vandersteen circles) when it was time to remodel the house and provide multi-room sound and a hidden 7.2 surround sound system I search high and low, read stacks of articles and ultimately landed at Inwall Tech.  I couldn’t be happier.  Starting from their support when a part of the shipment went missing and they fedexed out a replacement, no questions asked, to the ease of installing and the performance.

5 of 5 Great Value October 16, 2017
Reviewer: GKL from Peoria, AZ United States  
I will be ordering three more of these speaker.  At this price point they are an excellent value and the sound is very good. Didn't hurt that I was able to test them with a high-end av receiver, either.

4 of 5 Great Speaker...'almost perfect' May 12, 2016
Reviewer: Terry Huntington from Grass Valley, CA United States  
These speakers perform well beyond my expectations, and from a rating standpoint of price and performance, I would give them a five star rating.    My only caveat is some minor complaints about their build quality.   It starts from the lighter cosmetic inconsistencies in the grill to the clapping system where one of the long screws broke in half because two of the mounts were actually stacked on one speaker.   Also on one of the speakers, the tweeter is fairly difficult to rotate in a smooth fashion.   To boil it down it is an excellent speaker that needs a little more quality control, and I imagine when that is addressed this will be the perfect speaker for dedicated theater rooms, where immersive sound like Dolby Atmos becomes a nessesity.  Dont get me wrong though on the performance;  they are fantastic!

InwallStore.com response:  Thanks for reviewing the speaker!  The clamping system is similar to all the other brands out there and all have the same procedure for clamping.  See this video for a visual explanation of why the screws break if not followed:  https://www.youtube.com/v/kuBjIDIm-xo?autoplay=1
The pivoting tweeters also share the similarities.  There is a cup in which the tweeter sits with a spring behind it pushing it forward somewhat tightly so that it doesn't move after positioning it.  A rotation either a little clockwise or counter-clockwise un-impinges the spring behind in case it's been tweaked to one side or the other.  Then it frees up to move around.  Hope that helps future customers.  And of course if there's any problem that can't be solved, it's covered under a lifetime warranty.  Bk
