I just added another 2x10 and 2x12 to my big rig. Here's a picture along with my small rig (the 1x10s under the racks).
Essential elements...Big Rig - Pearce BC-1 or AMP SL-1 preamp into a QSC PLX2402 into three cabinets per channel (a 1x15, a 2x12 and a 2x10). The non-Avatars were built by me.
Small rig - same preamps into a Peavey DPC-1000 power amp into two 1x10s (each has a PAS 10 and Foster tweeter in box that is essentially half of a Goliath II Jr.). Sounds quite good!
