Thanks for the input, I appreciate it
Ok, assuming I can get some sound going through the different speakers I'll look into how to refoam those. A quick google shows that it may not be that hard to do or have done.
Here's a summary of what I believe I have:
1. Living room where the home theater system is: two Altec Lansing's in the ceiling, that 3 speaker woofer setup, and the subwoofer pictured previously.
2. Hallway/Foyer: two ceiling speakers, make/brand unknown.
3. "Game room:" two wall speakers, make/brand unknown.
4. Master bedroom: One (I think

) Altec Lansing.
5. There were also cut speaker wires going to the outside patio. No current speakers tho.
Again, thanks for all suggestions.
