Odd auction for a 292 "base driver" and 515B with no basket. Altec Lansing Speaker Drivers | eBay

Get yourself a voice coil and build a rotary subwoofer. :D

Cradeldorf, you truly are a spin Doctor:)

That was a deal for the 515 motor. 292 makes a nice doorstop or paint peeling midrange, i don't think there's much else to be done with it.
