Some use the omnimount...which attaches to the back of LCD?Plasma screens. Some have issues with it, though.

This is a good question, though, as I will be looking for something similar, rather soon.

I was thinking of mounting the flat screen to the wall...and the speaker could rest on the current TV stand, so that might be another way to go (unless you don't have a flat screen).

Good luck...and of course, I would like to hear others' opinions.
