The only GE's I know that have 8" speakers are the 6000, and 6035. There's also the Loewes version, the RS 2000 which is pretty bad ass!I looked everywhere for the one you posted but has no luck. If you find it let me know! Thanks!
Ps Now I'm interested in knowing all the mono boxes with at least an 8" woofer. I know the JVC 550 has a 10" but would love to see a list of the rest.
