1-12" cast frame woofer w/ 80oz. magnet, (Eminence Kappa Pro 12) power handling - 400 watts rms sensitivity: pretty loud impedance: 8 ohms dimensions: 14-1/2"H x 17-1/2"W x 13-1/2"D weight: 39lbs. I bought this cab used years ago as an extension for my GK combo. I stopped using it for a while and then put it back into service. I've since put a carpet covering on it (It looks good - I did a good job - see pix), "chevron" corners used by all the high end speaker builders, a metal grill similar to those used by EA, Bergantino, Aguilar etc. and replaced the driver with an Eminence Kappa Pro 12. The inside of the cabinet is heavily braced and insulated. I've used it maybe five or six times since making these upgrages; on its own and as an extenstion cab with an EA wizzy and EA iAmp 500. It's in great shape and has never been pushed too hard. It has 1 1/4" and 1 speakon connector wired in parallel. It's a great sounding cab but is redundant in my current cab lineup so it must go. $225 shipped to the continental U.S.
