I'd like to now sit down and take the time to attempt a proper repair. With the wedding being 2 days away at that point, I stuffed it to the side and went about finding a different set of speakers. I quickly killed the power to it but clearly some serious damage had been done. I heard a "things aren't going to work out for you" electrical buzz from the board for a few seconds before a loud pop and bad-news smoke started to rise. I left the speakers and sub unplugged from the board and plugged it in. I was trying to get the speakers working for my upcoming wedding (sound system for a small venue on the cheeeeap) so I quickly bought new parts based on a schematic I found online and popped them in. Further poking around with a DMM found most of the transistors on the board had continuity across pins and a cap had a slightly puffy top.
I popped open the subwoofer and poked around until I found a toasted resistor on the High-Frequency amplifier board.
I swapped the speakers around and got the same thing, ruling out a speaker issue. No sound on the left channel, and very weak/distorted sound in the right channel. Moved them back to my computer a few days later and found really weird sound coming from them. Used them for the sound system at a gathering (mostly people hooking their phones up to play music from them) and everything was fine. Hello everyone! I've browsed around a bit looking for some help on repairing some speakers that have gone kaput and this place looked really helpful! I've tried to repair this on my own almost a year back but was in a rush and found myself out of my depth in short order.
