I am a former audiophile (Damn that age / hearing business) with a
pile of gear I'm wanting to sell / swap. Is there any place that has a
list of vintage speaker systems, drivers, (possibly incl paramaters
reviews images etc.) wanted or for sale?

I have some "neat" stuff....for instance a styrofoam 10" non resonant
woofer with unsupported cone edge....or how about a foot tall
hemissherical electrostatic tweeter...or ....older audax isophone ,
epi, peerless, quad, vifa, JBL, altec, MBquart, etc.
