HELP!!!! Need Hales Revelation 3 Woofer

I need a woofer for Hales Revelation 3 speaker but the company is out of business. Any ideas where to find one?
Google suggests that the woofers used in that model were likely manufactured by Peerless.  You need to do some more research to see if you can find out exactly what type (model number) it was, and then see if one of the big websites that sells raw drivers stocks them.
Check with Madisound and Parts Express. I’ve had good experiences with both and they carry speaker components.
