Mission 70asa subwoofer: The subwoofer worked fine for years- now, when I plug it in, it immediately makes a very loud, distorted, unpleasant BBRRRAAAAA... sound. What's the deal? Is it toast?

Hi, yes there is a rather simple method for testing the actual subwoofer unit, simply plug in a known good rca cord into the input-make sure if there is a switch for level input that it is on the back make sure it is switched to line and not level, next plug in rca cord, turn on unit-stick tip of finger on tip of rca cable. This should gernerate a"HUMM" in the subwoofer if everything is working correctly. Thanks for choosing FixYa, I hope this was of some help,good luck Prodzilla.
probably the the wire connecting the cone and terminals at speaker are short.hold them with you fingers so that they cant move up and down with bass.if working fine then get them soldered.
Yea, now its time to replace it! the magnetic effect is weaken which makes the very bass low frequency sound to be distorted! You should re engergise the magnet of the subwoofer or should buy the new!
It depends on what you want. Is your existing solution a surround sound system (You only mention a subwoofer, what other speakers do you have?)?
Do you want full 5.1 or 7.1 surround sound? If you don't have this, and want it, your amp will have to be replaced, but your sub will fit in just fine. If you currently only have front left and right speakers, you will need to purchase a centre speaker and another pair (5.1) or two pairs (7.1) of speakers.
