  1. JB

    We just purchased more speakers and they are simply a sensational value. You can’t go wrong with this company!

  2. NA

    I purchased two pairs of HD-650.1C speakers. They are not installed yet so I do not know what they sound like, but the appear to be well-made and the packaging was excellent.

  3. SK

    This is my third purchase of speakers. This one was for my new home that included 8 speakers to make an 11.1 system two of which were in/wall speakers. I purchased the top-of-the-line speakers which are stocked full of quality and efficiency. The mounting of the speakers could not be easier. The systems sounds tremendous and as I hoped/expected from Inwalltech. Delivery was speedy and the speakers were professionally packaged to ensure no damage in transit.

  4. BR

    I had plenty of information from which to make my decision on the level of speakers I was searching for. The order process was straightforward and shipping was fast. Everything arrived packaged correctly and on time. Quality is excellent, just what I ordered.

  5. LB

    I know, I shouldn’t judge quality by a price tag and now I can add this purchase to the reasons why. I bought a full set of 5.1 speakers and 7.1 speakers for two separate systems, along with ceiling speakers for my whole house audio system. I spent around $2,500 with inwalltech whereas I could have spent well over $5,000 for name-brand speakers. I’m glad I didn’t waste the money because these babies ROCK. We are building a house, so I don’t even have my amp yet, but I hooked all of the speakers to a spare amp to test them (to be sure that a contractor didn’t skewer any of my in-wall speaker wiring) and even with a “spare” amp, these things sound AWESOME.
