Ultimate High Performance Audiophile Loudspeakers

Premium, luxury, preeminent, supreme, unparalleled, paramount, primo, leading, first-class, finest, precious, life-like, extravagant, etc.

Get ready because you’re looking at the most performance you can get out of an inwall design before paying exotic prices. This line delivers luxury fulfillment of life-like audio reproduction. Envision a home theater capable of immersing you into the true embodiment of the movie director’s dream.


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

  • Vivid high end and unassuming midrange performance for greater accuracy and more life-like imaging, taming the shrillish properties of typical Titanium with Zelenium-Dome™tweeters. Our improved version of Titanium, also 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.

This ceiling theater speaker is angled 20 degrees inside it's frame. So you can use this for Home Theater applications where you want to aim ALL the sound to your listening area, not just the tweeters.

5 of 5 Great speakers, great price, great personal servic March 16, 2022
Reviewer: John Maurer from Stuart, FL United States  
I was so happy to discover InwallTech.
We had gotten a proposal from a Home Theater contractor.  I couldn't understand why speakers cost more than a "near top of the line" TV.  This put the whole job beyond our budget.
Thinking DIY, I looked for speakers at Best Buy.  Again, I couldn't understand why good (not best) speakers were so expensive.
I found InwallTech online.  It appeared they had good speakers at good prices.  Astonishingly, you can schedule a 20 minute telephone consultation.
I got a phone call from Brian (the owner).  He listened to my desires & explained differences in speakers (materials, crossover, etc.).
I asked for 2 recommendations, one for their top of the line speakers and another for one price point below.  Prices were so reasonable I went with the top.
The sound is great!
I got all 5 speakers (Kevlar and Titanium) for less than 1/2 the cost of name-brand polypropylene speakers.
PS: Our family room seems larger with the speakers in the walls.

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.
