So, how did you dial them in? I'm going to see what I can achieve via "flattest frequency response" as a starting point, but figure I'll start playing around from there.
Looks like I get the house to myself for at least a couple of hours on Friday, so I'll try reading up on the various settings and possibilities til then.
I'm not Chuck but I used a combination of starting by placing them 3ft from the wall then with one side at a time playing, moving the speaker back and forth into the room until I got the best base I could within the amount of room I had to work with. Then I did the other side. Next I moved them farther apart, again within the confines of the space I could maneuver in till they sounded best. Then adjusted toe in to center a vocal image.
After that I connected the computer and used REW, running 15Hz-300Hz frequency sweeps, to adjust the crossover points, again one side at a time. Since I was using the Otica MTMs on top of the H-frames I shot one of the MTMs (sub off) first and determined where its 6dB down point was. Then I turned the MTM off and shot the sub and adjusted the crossover until its was 6dB down at the same place the MTM was. Then I turned on both the sub and MTM and ran REW to see how well they blended. Then tweaked the crossover until I got the smoothest response. Then I turned that channel off and did the other channel.
Next I went back to one channel, both MTM and sub, and ran REW frequency sweeps from 15Hz - 20kHz looking for peaks, adjusting PEQ parameters until I got the smoothest response. Then I did the other side.
Now it is fiddle time with the extension, damping, and filter, etc. switches, rerunning REW after changes to see if I needed to readjust the PEQ settings.
Then sit back and listen. Then walk away for awhile. Then listen again and see if you still like it. If so done. If not, fiddle some more until you do like it.
I'm sure there are other ways that would work also.
