There's some confusion here. Not trying to match 2 subs in the same room. Here's the setup:
Room 1 - pair of DQ-10's and one sub (music only)
Room 2 - Pair of DQ-10's....AND....in-ceiling surround speakers...both of which utilize sub #2
So my question is, what would be a good powered sub recommendation for both arrangements, given that one is solely for music and the second sub serves as BOTH a music and a surround sub?
