For sale is a PAIR of Deltalite 2512 (Avatar Spec) 8ohm 12" Speakers. I measured the ID incorrectly when selecting these for a replacement on a spare cabinet I have. Never even got a chance to mount them. My loss your gain. Below are the specs for these speakers, they modeled well for my needs in WinISD.
