I am thinking of going to a combo to replace my semi large and heavy rig. Right now I use a Carvin 2x10 and 1x15. Usually not the 1x15 since it is so large and most gigs we play do not call for it. My amp consists of a mackie 1400i, ADA MB-1, BBE Sonic Maximizer, Sabine 1600 rack tuner and a power conditioner. As someone with a back that does not dig the weight I am looking for a combo with either a 2x10 or 1x15 speaker and anywhere from 400 - 600 watts RMS. I have read reviews on carvin, swr, etc.. What do you guys gig with that you are really happy with. I just realized I do not need all this power. Any help is greatly appreciated. Thanks.
