Hi all,
I have decided on axiom speakers for my home thearter. Now it's time to pick out the sub. I think i will get HSU. However, there are two models, STF-2 and VTF-2.I think they're both pretty much the same , except the price is $100 diff. Could you please share some experience with these sub? which one should i get for my 12x14 room size.

thanks a lot.
