I have just finished setting up my HT system. I am running a mix & match system comprised of a Marantz SR5500 receiver, Polk r30 fronts, Dahlquist centre and sub and JBL surrounds.
The Subwoofer is a QX-100, self powered 8" polypro. cone and aluminum basket driver, BASH 100 watt integrated amp. Volume is adjustable. I've hooked it up to the Sub Out on my receiver, and directly to the LFE input on the sub.
I've set my amp's crossover to 80, and the adjustable crossover settings on the back of my Sub to about the same. Music sounds great so far.
PROBLEM: During playback of many movies, during more bass-heavy scenes, explosions, etc., I get this disconcerting popping sound from the sub. I'm assuming it's bottoming-out, so I have to adjust volume on the sub to compensate.
I am not a bass-crazy listener, but I do like to listen to movies at moderately loud levels. I feel the sub just can't handle the heavier tracks in some movies and am wondering if I can adjust this or should I just go for a bigger sub (10-12"). Is this frequent? Is it a crappy sub? A friend's Energy 8" sub seems to do fine on these tracks.
Thanks for your HELP!
