I got in on the tail end of plasma... lol I bought a Bose sound bar and sub with it. It cost more than the TV and was worth it to my ears. It has some kind of active EQ and 3D sound that adjusts it to the room. You sit where you intend to view and put on a headset that has mics in it. It plays a bunch of different frequencies left right and center and when it's done you can point to places in the room where the sound seems to be coming from depending on what's happening on the screen. Something crashes on screen and you look to see what the cat knocked off the table. Lol.
