Could be coils or spiders

I've had two different Boston Acoustic woofers that buzz despite several attempts and I've successfully refoamed mayebe 50 or 60 woofers. Sometimes the VC delaminates and I think sometimes the spider may be slightly off or sagging.

As far as replacing the Allison woofers you need to try and match characteristics. IF it is acoustic suspension and there is no low pass filter(coil) to the woofer that is the hardest. I was able to use EPI woofers to fix one set of the aforementioned BA's because they were both AS in similar size boxes, about the same efficiency, and both had approximately the same natural roll-off frequency. If there is a low passs filter in becomes a little easier to use a replacement. Talk to the tech support at either Madisound or PE and they probably can help find the least of evil match.
