I’ve got some ancient Radio Shack bookshelf speakers in my office.\u00a0 These things are at least 30 years old. They sound horrid but until today they were indestructible.\u00a0 But today, the woofer in one stopped.\u00a0 No bad noises or anything, just all the sudden nothing except tweet in one channel.<\/p>\n
So I pulled the grill off to find the suspension missing.\u00a0 Whatever crap they make the foam surround out of, it had totally rotted out.\u00a0 The only thing holding the cone in place was the spider.\u00a0 Kind of gives a whole new meaning to “air suspension”.<\/p>\n
I replaced it with a not so great woofer that I used to have in a tower speaker.\u00a0 It doesn’t have an adequate magnet, won’t handle a lot of power, but still it’s a step up from what was there, still has it’s suspension intact and still works.\u00a0 So now bass in one channel digs down to, oh, about 80 Hz.<\/p>\n
I was going to replace the other while I was at it, since I have two of these and know the suspension on the other has to be in the same condition, but the little cap that covers the voice coil fell off the other spare so I’m gluing it back in place before I replace it.<\/p>\n","protected":false},"excerpt":{"rendered":"
