Thanks,
I'm using an old Kenwood bookshelf system for the front L/R; not sure about the center yet. The Kenwood actually sounds alright; it's about 10-15 years old now. It is not exactly the last word in imaging, but the sound is pleasingly full. I have a few pieces of different systems floating around which I can try for a center, although the room is small enough that it may not really be necessary (don't know yet, haven't tried). This isn't a high-budget project; I'm basically just goofing around.
