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) |
power surge?

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 ...
craig. |
so you mean....like essentially because i don't have a subsonic filter and the sub is try'n to play stuff that's too low???
|
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.

My bet is that its the voice coil hitting the back plate... [img]graemlins/thumb.gif[/img]
