i used a lousy cambridge soundworks powered 10" in my first ht setup. when it died, I didn't bother looking into it, I just upgraded. now Im thinking of reviving it as a second sub in my setup. It just stopped producing sound one day, it didn't die during use, I just turned it on one day and nada. The fuse is good, and the power LED is on, the sub itself is not damaged per say, it moves air properly when I pump it with my hand, its not blown out, seems to be an electrical problem of sorts. Where is the best place to look first? I will probably open it up and see that a lead wiggled loose :b but I figured some knowledge passed on would be helpfull before I dive in.
