Ed Meitner modified many Acoustat Panels. Maybe he could help. He made them sound wonderfully. Never heard anything close to this for the fluent midrange, the presence... You could get in touch with him on a/d/s/ site : http://www.cadvision.com/ads/museatex.htm
Acoustat Panels
I am a speaker builder and have inherited some ACOUSTAT 2 + 2 ELECTROSTATIC speakers. They have the Medallion mod (all Mylar or polypropylene caps). They have a dying transformer and I want to repair or sell these for parts. It frustrates me cause I heard one (the left one) and they were pretty darn good! Looking for solutions. PS If I can help on speakers, I would be glad to, I build mostly high-end stuff. Thanks
