    I picked up this cab for $200 with a blown 12 in it. I searched online and the factory replacement speakers are $140 a piece. I'd prefer to put some Celestion "Green Label" in there but the ones I want to use are only available in 8ohms & the cab is wired for 4ohms. I have included the specs for the cabinet below & just want to know if I can simply wire it differently to put those speakers in there or if I'd have to use the 4ohm "orange label" 12's.

    Specs from the SWR site:

    Hi Fett.

    Properly ported cabs need proper speakers to work properly. :D

    Seriously...
