<<Yeah, car subs almost always pack more of a punch.>>
I have to partially retract what I said earlier and say that HSU
Research makes a 12-inch car audio sub with impact and Db levels that
are fairly unbelieveable. In a car environment, where I heard the HSU,
I think it's as loud as a single 15-inch Cerwin Stroker, but cleaner
and more accurate. However, it's hard to say how the HSU would perform
in a home environment and I've not yet had a chance to demo any of
their home subs, which I understand are stellar. I've also had the
chance to be in an extended cab Chevrolet S10 pickup, which had FOUR
15-inch Cerwin Stroker series subs in a custom enclosure in the cab
area, behind the front seats, and a fairly high end 3-way system for
the front. Needless to say, the bass was pretty overpowering, not
exactly my idea of an "audiophile" grade system, but the truck was
insane and it literally felt like it was going to shake something
loose. The truck had at least 2 aux. batteries to help run the system,
which included an in-dash screen and DVD playback capability, although
they couldn't get real 5.1 from the system without rear or center
speakers.
