I have a black, not that the color matters, 3x15 cab. that I put in the Eminence Delta 15s. IT ROCKS! I used 16 ohm speakers so the cab. is close to a 4 ohm cab. With the 2x15 you may want to use the 8 ohm speakers so your cab. will be 4 ohm - Kustom heads seem to like 4 ohms. Or you could spend big bucks and buy my rig, it is for sale, and WOW your could blow windows out and chairs over!
