I built my first "multi-media" room in ~1984 (Mitsubishi TV, surround processor, laser disc player). In 1991, I visited an audio store in Beverly Hills, saw my first "real" home theater, and went home and replicated it: (Sony 1251 projector, Snell THX speakers, Frox surround/video processor, two Velodyne subs).
And it hasn't stopped.
I am hopeful that this newer forum will blossom and be very successful.
