I picked up a second pair of SM255's the other day, got them for cheap since they needed foam. In removing the old foam I found that both woofer voice coils are separated from the spider and cone completely and the coils, (visible through the frame), are burnt.
The mids, tweeters, and crossovers all look fine?
The only thing I can figure is that they drove the woofers to death after the foam rotted away and cooked the voice coils?
These woofers are aluminum framed, and appear different than those used on the SM155 model.
I'd like to find another pair of woofers for these as the cabinets are minty perfect. Not so much as a scratch on them.
The woofer p/n is 333513-001, its a 15" woofer.
I thought about just replacing the voice coils since everything is basically unglued already, but the voice coils are super long, they're not that large in diameter, but over 4" long from the cone to the bottom. There's a long distance between where the woofer stops and the windings begin, about 2 inches and the coil former is perforated with large holes I suppose for venting?
Did they use these woofers in any other model?
Any idea where to get replacement parts to fix these?
The woofer is listed as being 3.6 ohms DC resistance on the spec sheet.
