Not really a theater, but it is my main Netflix, DVD, Movie, Series -setup. Top-photo was until last wednesday, but bought a new TV:
it's a 49" LG tv, the 49sj800v. It's in my living room, I don't want my TV to overshadow the living room ambiance, in case you're wondering why I didn't opt for the 55 or 65" versions.
Joining in is a Samsung 2.1 set, a cheapass one with a BluRay player and bluetooth, but hey: it gives me 500 watts RMS
