edit:

i'll just try to explain it a bit better:

Everything was going good, rocken out to some tunage when I decided the time had come to rock harder. As I turned up the volume my sub just suddenly quit working.
My satellites were working but the sub wasn't doing squat. no hum, no nothing! I thought it was dead. I'd seen a bunch of stuff on the internet about caps and resistors going bad but everything looked fine. The problem was actually on the subwoofer speaker itself - the boards and fuses are alright.

I had the power on playing some music messing with the subwoofer connectors to see if I could get any kind of noise out of it. I noticed when I plugged the negative side with the positive already in, I'd get a noise as I was pressing it on - the harder I pressed, the more noise I would get. I figured something was up with the connector on the speaker then.

I took the driver out to get a closer look and noticed the solder job connecting the negative voice coil wire to the tag wasn't done so great - it looked like it had become loose. I pushed the negative side of the tag against the wire and I'd get a really ugly/staticy sound similar to a blown speaker. I got some solder and just put a decent sized glob over it. I still had an ugly static noise under heavy bass and I noticed the cone was actually just hitting the wire when the it was under higher excursion, so I just bent the wire and the tag with my pliers to give it some clearance.

I put everything back together and I had my normal clean sound back.

hope that helps somebody

I bought some used promedias off of ebay because I needed some speakers for work.

they worked fine for about 2 weeks when just last week while listening I had noticed that my subwoofer suddenly stopped working. I didnt hear it make any noises - it just quit. I've got the amp panel off - not too sure what I'm looking at/for but I don't see any exploded caps.

both of my speakers still work totally fine, it's just the sub

any clue on what could be up?
 
something up with the black speaker wire, jiggle it and walla sound!

tho it sounds like i may have blown the speaker =\

anyone know where i can order a replacement?
 
nevermind...

the black wire wasnt connecting so well and was also hitting the cone... threw some solder on it and its working totally fine

useless thread i guess :eek:
 
I have read this is a semi-common problem with the promedia speakers from what I have read, it is one of the things that dissuaded me from picking them up long ago. That and the fact that I <3 my Infinitys. Nice that you fixed it. You might want to edit a post with some ref to how you went about it (assuming you didn't just figure it out on your own, which is most likely).
