Here's the thing: I was thinking of selling my Genz Benz Neox 212T. Reason is, I haven't really used it since I bought it 6 months ago. I've been playing rehearsals only and found that carrying those 65lbs (it's one of the earliest models, with rat fur cover) with an unrepleacable broken wheel is meh. My head is a GK 700RB II, Using a PBass with TI flats. I know for sure that I'd have more than enough volume with the Neox for my needs. I was thinking of buying a 3015HO loaded 1x15, a la Barefaced Compact. It's gonna be a bit heavier, 15-17kg versus 12, still HALF the weight of the Genz though. Tonewise, that speaker should pair well with a classic rock Pbass sound, especially since with flats I don't need a lot of high end content anyway. But, volume wise? A single 3015 should be within 1-2 dB of efficiency compared to a pair of Deltalites for the most part of the frequency spectrum. It will have less highs and less of a peak in the high mid region, but more lows and the same low mids of 2x12. I will be getting another 1-2 less dB out of maximum output because it will be pushed by 320Watts instead of 480. I used to have a Orange OBC 115 with the same head, it was ok but not plenty of headroom left and had a strange sound, not enough lows and a very boxy sound with that Kappa 15A and no foam inside. That was another band though, with a much louder drummer. I was even considering going for a 4ohm Faital 15PR400 route, but the lower impedance benefit would be negated by the lesser efficiency. I should go for it only if I really like the sound i suppose. What do you think? In terms of maximum output will be too much of a downsize and not worth it compared to my current cab?
