home theatre sub makes a POP noise once in a while.....why?
#1
OK, well it's actually only happened twice. But i'm concerned as to why, i've got a couple ideas either volume or too low, which i thinka re the only real options or a combo, but i'm not sure.
the sub in question is a paradigm pw-2200....when listening to music of movie (once each) at louder volumes the sub has made a POP sound, i'm usually quick to turn things down a bit cause that always makes me nervous. The first time on the music, it was a rather low bassline up loud, last time was just watching the third lord of the rings....
whats causing it? what i'm i wrecking?
Sub's internal amp is turned to about 45% or so with it's cutoff freq set to about half (can't remember the range), and the receiver volume panasonic sa-xr50 was turned up to about 30 (counts down)

I've had this sympton. It happens when the subharmonics resonate and get out of sync with the driver - usually this is at higher output levels and without a filter cutting out say below 30 hz. Once I used a subharmonic filter the symptom never reappeared. I'm sure someone here can explain it better...also I'll try to find where I got this answer when I had the problem myself - of course I can't remember if it was avsforum or audioasylum or audioroundtable or ...

it trying to play something at the resonant frequency of the sub. Especially noticeable when there is processing added to the signal. You can eq this away also - just lower the eq for the sub's resonant freq.( what it's tuned to ? ). I still can't find where I got my answer.
