That is what I was thinking Rick. The problem I'm having is trying to calibrate all my subs (3 now). I'm doing them one at a time. I moved the 600 near the back wall, and have the twin 350v3's on the front wall.
I've tried calibrating them all seperately, then turning them all on, which jumps the SPL like 9dB higher then where I calibrated them. Am I supposed to calibrate them low, so the sum equals the end goal? I know Ian in the video says the increase is not what is seems as the RS meter does not read below 50hz well. However when I sweep using the SMS-1 mic, in NON EQ mode, the low freq's are way to high.
Another weird problem is that I have to turn my ep600 volume knob all the way to the MIN selection, and still have to put my Denon on like -5 to -6dB's to achieve 75dB's on the meter. Then when I add the other subs up front the meter spikes above 80dB's and I have to crank the volume on the 350's to about 60% since the receiver is so low.
Another thing that is weird is that Ian says the front subs should be at 0 phase, but when I switch them and the 600 to 180 phase the graph with the SMS is very flat, not like when they are on 0 phase.
This is so much fun. arggggggggg
ps: one thing is sure, these 350v3's put out some serious LFE for the price.
