I have had 3 different Hsu subs, 2 VTF-2 MK1s and a STF-3. Hsu make one heck of a sub for the money. As of right now I run an eD A3-300 and must say it does best the Hsu models I have had.

eD has some really great subs for the money. I can and have recommended them to folks that want some serious woofage for their money.
