Everybody knows the only sub worth buying is a Pioneer/Premier TS-W8102SPL...
In all seriousness, I used to use Pioneer TS-W305C's all the time, and probably the best setup I had for SQ was a pair of TS-W255C's in a sealed, separated box, run by a pair of Kenwood KAC-729S's.
I can't speak for their current stuff, or any of the other stuff you're looking into... if I were looking for a 10, I'd probably buy this at the moment.
