There were not a lot of reviews for these speakers and frankly, there are not a lot of reviews out there for ultra thin ceiling speakers. I, unfortunately, had to use ultra thin ceiling speakers for my rear height speakers in my home theater because they are under my duct work in the basement. After spending way more time researching thin ceiling speakers I ended up with these mainly on price. These cost a fraction of the price of the Klipsch or Kef ultra slim ceiling speakers and so I figured they would be worth a shot. After getting them setup they sound way better than I expected and after running Audessey on my Denon AVR these were marked as going down to 100hz, which is way better than I expected. Frankly these are speakers have much higher quality sound than I expected considering how thin they actually are. They are also very very heavy. I was frankly shocked on both fronts. 100% would purchase these again for any use case requiring ultra thin ceiling speakers.

It would not work with my amp. I have 10 other Sonance indoor speakers and the 6-speaker outside system that sound amazing. This unit would not work where all the others would.
