The 3- JTR 215's supposed to have the bass output of one orbital shifter (OS). So I will start out without separate sub(s). But if bass is not enough, there is room for 1-2 Marty/Chaluga DIY boxes, or couple of S2's behind the false screen wall.
The room will be pretty, with surrounds in the columns, crown molding etc. so the only option for sub boxes is behind the stage..no matter what the USB microphone/REW S/W
Like you guys say- cheaper to put in the power now, run one 30 amp dedicated, and a few 20-amp dediatced in the equip. room, and maybe two 20 amp dedicated behind the stage.
I guess I was reading too many 27.9 amp crown XTI, sine wave benchmark test posts, I needed you guys to give me a reality check...Of course the poster, was using the amp for a 1000 person music festival at the park. I ignored that part!
