I just got a GK 410RBH and 115RBH in a really good trade today and I love them. I'm mostly playing electronica and hip hop at the moment, and these cabs really sound great with my pre/power amp rig. My real issue is their size, weight, and how difficult they are to transport. I'm thinking that I might be better off with some lighter and smaller Neo cabs but I'm really sure what would sound best. I need a pretty full range, low frequency response for sub octave stuff and enough high end response to give a lot of definition to filter sweeps and fuzzed sounds. I do want to stick with 2x 8 ohm cabinet setup. Do you think the 1x15 and 4x10 combo is the right way to go? I'm also thinking about 2x12's. I could run a 1x15 and 2x12, two 2x12's, or a 2x12 and a 2x10. I'm looking for advice and experience here.
