I have two 8-ohm cabinets, an Ampeg SVT 210HE (2x10 and a horn) and an SVT 115E (1x15) that I might be interested in trading for 2 4-ohm cabs, or possibly one 8-ohm 4x10 cab with a fairly high power rating.

I'd take a look at:

4 ohm
2x10
2x12
4x10
1x15

8 ohm
4x10
1 cab with different size speakers (probably not a triad, but something those lines)
