  • 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.

  • 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.

    The sound quality was everything I had expected. These speakers replaced some old RTR towers creating more space and delivering a balanced high-quality sound. The mounting systems versatility allowed me to place one of the speakers on an outside concrete wall that was shallow due to the foam forms depth. I glued some 3/4″ oak boards to the sheetrock and the speaker’s clamping system did the rest. No vibration or resonance in either wall.

    I bought the “THE PIONEER SQUARE” theater package in Oct 2013, but recently needed an additional speaker. I contacted the company, and Brian (the owner) quickly followed up. After installing the new speaker, I was prompted to leave a review (good or bad), so I though this would be a good time to review the speakers that were installed 5 years ago. The build quality and magnet size on these speakers compare to the high end brand name speakers that I have used in the past. They have worked flawlessly with incredible sound for over 5 years in our dedicated home theater. They are paired up with an Onkyo high current receiver and stand alone powered subwoofer. When I first made the purchase in Oct 2013, I was skeptical, because I could not find much information on the company. I am now a life long customer. Quality and price can’t be beaten, you won’t be disappointed.

    Recently purchased your INWALLTECH® HD525.1LCR. I needed a great center channel speaker for my theater room. The family could hardly believe the difference it made. The sound is so clear and full. We were turning the volume up so loud to understand conversations, but now the clarity comes through. Years ago I discovered your store when we purchased in-ceiling speakers for our new construction home. Installed them myself and did a bang-up job, if I do say myself. It was so simple. Thanks for having great products and easy to follow instructions…

    Build quality is outstanding at this price point. Easy to install, and the template was spot-on for cutting the drywall. I installed these at the L, C, and R positions in my dedicated theater room, replacing an old set of Energy Take5’s. the sound is very full, and really fills in the midrange – something I was missing with the Energy’s. Having the ability to dial up or down the individual driver dbs is very helpful for tuning within the room. I just ordered the HD650.2 for the surrounds…

  5. SR

    Makes a good match to the HD 650.2w speakers. 2 directional tweaters allows for good sound adjustment. Strong mid-range sound for dialoge
