I currently have two GK neo 112 series II. Dont really have the cash for a 2x12 in the same brand, nor do I feel like hauling around a conventional 2x12 with ceramics. Figured 3 could be very useful as far as loud gigs go. Or just to have the that much air available to move. Also, on a lot of gigs, 2 will do. So leave one at home or rehearsal space and have two available for gigs/work. I have an amp that does 2ohms, so that isn't an issue. Don't hear much about guys running three of them. Usually a pair of 2z12's is more often seen.
