For theater there is nothing I heard that can outperform the Genelec powered inwalls. I have heard a vast majority of the inwall speakers out there(B&W, Paradigm, Snell, Sonance, Monitor Audio, Speakercraft) and some are very good, but for sure output and clarity in my opinion these are the best inwall speakers for a theater.
Best Sounding In Walls
I am basically a two channel guy. I have a dedicated listening room for music however I am building a theater room in my basement and have decided to maximize space by going with in wall speakers. Would like to get information and experiences from those of you who have gone this route. Any and all information is welcome.
