anyone running three 2x10's?

I've had this crazy idea to run three 2x10's
two 8-ohm and one 4-ohm.

My SVT 2-pro runs either 4 or 2 ohms, my BX500 will run, 8, 4 and 2 ohms

The above three-cab situation can be used in the following ways:
for BX-500
one 8-ohm @300 watts, one 4-ohm @ 500 watts, two 8-ohm (4-ohm lead) or two 8- and one 4-ohm for a 2-ohm total load

with SVT
two 8-ohm for total 4-ohm load, or all three for 2-ohm load. (I wouldn't want to run the SVT with one 2x10, although I could use the 4-ohm...I was once testing a 4-ohm 2x10 with the svt and somwhow got the amp to go into protect mode...never happened before, never happened again)

I currently have a Goliath II 4x10 and Goliath II jr 2x10, which I'm quite happy with.
I feel like trying something new, but not sure it's worth it.

I'd definitley want to get all 3 matching cabs, but it seems there are only a fistful of companies that do offer 4-and 8-ohm 2x10's, like Carvin (BR series), Avatar, SWR (though it might be best to get just two 8-ohm SWR 2x10's to match my existing one instead of buying 3 new ones...)
What are the chances it will sound better or worse than my current setup?

The issue that you'll have is that the 4 ohm 210 will be receiving twice as much power as either of the 8 ohm 210s.

Unfortunately, for this to work ideally, you'd need either two or four 8 ohm 210's. Or three that somehow clocked in at 6 ohms.

that's also kind of what I'm getting with the current setup, the speakers in the 4x10 are getting less power each compared to those in the 2x10.

Huh, when I read the thread title, I was thinking you were thinking a biamped rig - two 2x10's for the bass and one on top for treble/midrange would be a killer, and super modular rig - but all three full-range seems strange (silly) for the reason Christw stated.

You could, if you wanted, just get three 8-ohm 2x10s for full-range use - I think that you can finagle a 2.6 ohm load from that, which is totally fine to run off a 2-ohm output.

Not crazy at all. And well worth pursuing - as long as you stack them vertically (end on end), for a nice tall, skinny stack...

Get three cabs rated at 8 ohms each, along with a high-powered head that's safe at 2 ohms - and will put out approximately 800 - 1,200 watts into an 8-ohm load.

Should sound very nice...

A tower of tens! I'm sure it would be awesome.

or just get 3 4Ω 2x10 cabs and power them all with a fender 400-PS.

I sometimes run 3 Edens, 210xst x 2, 210xlt. Shuttle Max 12, xst's on one side, xlt on the other. No tweeters in the xst's. Outdoor set-up. Great tone, but, rarely do I need to be that loud.

3 8 ohm 310's work out to 2.67 ohms which either of your heads will do safely. The Carvin is limited at 500 watts below 4 ohms, so with that there's no reason to go all the way to 2 ohms.

I have run this rig for larger shows. Sometimes with just one 410. The 210s act as front monitors to give me more personal volume without more audience volume. Works great.
