The other way around, an 8ohm 15 and a 4ohm 210. All three would be getting roughly 1/3 power. You'd need either a 2ohm stable mono head or a stereo head.
I've got the 2 Ohm head already.
I also have a bunch of cab combinations and I just LIKE the 115 in the mix, but only at lower volumes (50% or less). I've been fortunate to not bark the 115 so far.
I might be fooling myself here though to think about it. The 115 takes the amp down a few Ohms and maybe the added Wattage makes the 10s sound a little bigger. I dunnow.
Yeah - the 810 and another 410 with the 2 Ohm combo with ANOTHER set of 210s is awesome! That's 14-10s. Seriously I don't even need that much air in motion, but it's nice to have the capacity to do it.
Sometimes I use the 210 combo and a 410 underneath it and it's all well and good too.
