I am in search of a new sub to replace my Existing klipsch LF-10. My HT room is 6,000 cubic feet. I have read the review on this forum between the Hsu STF-3 vs the SVS PB1-ISD, with the winner being the SVS. Is there a review looking at the SVS vs the Outlaw, or has anyone done a side by comparison. I know the Hsu and Outlaw are similar subs, however ther are some differnces (amp, Driver, down firing ports vs rear etc.) I would appreciate any help on this. Thank you.
