Econowave'd Advents August 22 2012

I just spent a bunch of time in the basement "breaking in" my new Advent econowaves.  By breaking in, of course I mean blasting music while freaking out.  Good stuff.  For some reason these sound better louder...
 These Selenium compression drivers sound great.  I am bi-amping them using a 4 channel Yamaha MX-35.
Foam surrounds, made in the 70s,  can be so brittle that they look perfect, then basically explode.  Not even Weld-Bond glue could save them.

A rare glimpse into the lab.  Can you count the unfinished projects?
