I have read that this sub has some rave reviews. After a heads up, I went to compusa and picked one up. I installed it in my current setup(HK AVR325,M22ti,vp100,HK HKSUB 12. I am thinking the HK sub does better than this hsu. The hsu does go a tad lower but it seems to "bottom out" way faster than the HK. Is the HK 12 a decent sub? Does anyone have any experience with the two or can offer some insight? Both x-over @ 80hz. Thanks,Blake
