Good to know about the 600s.
I don't know what the correct way is of setting up multiple subs. I'll try to summarize what I did. I used logic but I'm not sure if my logic is logical. It sounds good. Maybe it can sound better if I was Trevor.
The essence of this is that I set up each active and its 500 individually so that they both sum equally to 73dBC at my MLP. The reason for 73dBC is that I sometimes use the "double-bass" setting on my Onk. This routes the left and right channel bass to my 800. That gives a nice boost at my MLP.
A. Preliminary steps
1. Dedicate the 800 to the .1 channel
2. Turn off the 800
3. Set the actives to full range
4. Set each 500 to 40Hz.
5. Set both 500 gain knobs to half-way
B. 500 phase adjustment
1. Turn on the left active and 500. Ensure the right 500 is off.
2. Play a 40Hz tone. Vary the left 500's phase knob until the SPL peaks at the MLP. I could have used a friend's help with this but I didn't want to skew the response so I used binoculars. LOL!
3. Shut off the left active and 500 and turn on the right active and 500. Repeat step 6 with the right active and 500.
C. 500 gain adjustment
1. Shut off the right active and the right sub
2. Play pink noise. Set the left 500 to 70dBC at MLP. Turn off the left active and 500.
3. Play pink noise. Turn on the right active and 500. Set the right 500 to 70dBC at MLP.
4. Turn on the left active and 500. Play pink noise. Measure the combined SPL from both actives and 500s at MLP. If not 73 dBC, incrementally adjust each 500 to reach 73dBC.
D. 800 phase adjustment
1. Turn on the actives, the 500s and the 800. Set the 800's gain knob to 1/4 way.
2. Play pink noise. Vary the 800's phase knob until the SPL peaks at the MLP.
E. 800 gain adjustment
1. Shut off the actives and 500s
2. Play pink noise. Set the 800 to 75dBC at MLP.
