Help replacing 8" woofer on Gershman Avant Garde Rx-20
In a bit of exuberance while my kids were out of the house, I went past 50% on my amp and blew out my woofer on my 10 year old Gershman Avant Garde RX-20.
I believe it's an 8" ribbon driver? Looking for an exact replacement or an upgrade to both.
Any suggestions? https://www.soundstagenetwork.com/revequip/staff10.htm
