I only have a 11x13x8 room right now for HT and have a
Paradigm PDR-10 10" sub. I am thinking of getting a 12"
sub in the future in case I move everything into a larger
room. Who has the best 12" subwoofer in the $600 range,
Axiom, HSU, or SVS? Also, would this be simply overpowering
if I was to use the 12" in my existing room?

Many Thanks,
Tim
