A:Answer I just had Bowers & Wilkins ceiling speakers installed with a Denon Dolby Atmos receiver earlier this year. I remember having these concerns of sound and function quality. 6 months later and many movies and music played, I couldn't be happier with it! I wont go to the movie theaters anymore. The quality of sound is so great, even now when I turn a movie on or play music, it brings a smile to my face at how clean, crisp and well balanced the sound is. Guests I have come over are wowed by the sound as well. I literally have had no problems with these speakers and I also went with a Bowers & Wilkins floor subwoofer, which seals the entire deal. Hope this helps.
