At my bands show tonight, assuming we can fit it all in our van, I'll be running..
Sunn Concert Bass (200w)
Sunn Concert Slave (200w)
Earth Sound Research Producer (220w)
Into...
4x10
4x12
1x18
2x15
2x15
If we have room, I'll be setting up the two 2x15's to the left on their sides, and stacked on one another, in the middle will be the 4x12 with all three amps stacked on top, and on the right will be the 1x18/4x10 stack. I've never run this setup before. Always wanted to though.
Unfortunately, due to a possible small claims court battle, I'll be losing one of the 2x15's soon, which is why I'm planning on running this larger setup tonight. Should be interesting.

Like I said, we're not even sure if this will all fit in the van, if it does though, I'll try to get a picture or two of it.
