I just picked up 2 JBL GT800 off ebay for less than 50cad for the pair, they look to be fairly well kept.

I'm planning on putting them in a sealed box, separate chambers for each sub. I know that working around .35cf sealed for .55cf ported is pretty average for an 8" woofer, but I'd love to get some more details on this sub. JBL has the manual for these subs on their website, but it doesn't contain any specs at all. I can't seem to find them anywhere with the standard googling.

Curious if anyone has a resource available to them for these specs that I might not.

Thanks.
