Sorry for the long post below.....
I recently upgraded my amp from an Acoustic B100 MKii to a GK MB210. I'd been thinking about selling the B100 and putting it towards an extension cab. I knew I liked the sound of the 15" but the B100 wasn't very loud and was VERY heavy to lug around. After weighing my options, I decided to convert the Acoustic amp to a cab. Took the amp out (only 4 screws holding it in), installed a speakon input jack, and plugged it in the the GK. WOW!!! I'd never played through a 210/115 rig before and it's got every bit the volume and warmth described in these forums. The dimensions of the two match perfect, and the 115 cab is now under 50 lbs. I installed rubber feet to the sides of both cab's to stack horizontally vertically. Total project took very little time and cost under $50 (cable was the most expensive component). I'm making a frame for the B100 amp and installing a speakon jack to give to my son.
Wins all around!
