...when using xt32 in my situation?

i'm running two trinity's for 50hz and below...two mbm 12's for 50 hz and above.

would you run the trinity's together off of sub1 out, and the mbm's both off of sub 2? (option 1)

...or run 1 trinity and 1 mbm out of sub1, then the other pair outa sub 2? (option 2)

What receiver do you have?

Many of the receivers which have two subwoofer outputs are simply providing an internal Y connection between the two. They do not calibrate the subwoofers separately.

Only if the receiver's hardware supports it.

I think you'll have to calibrate all four subs separately, depending on where they are placed. That is more than what XT32 can do I believe. Are any of your subs co-located? That would make it much simpler.

that's a good point shady...

but they are not exactly co-located...each mbm is about 30" from a trinity

again, depending on which option used, wouldn't it be best to turn off one sub on sub1, set level at 75 as per audyssey, then turn that sub off, turn the sub sharing that sub1 input on, set that sub at level 75 and then turn on other sub and set combines level at 75 and let audyssey calibrate from there? (doing the same routine with the subs on sub2)


make any sense or am i not thinking this thru...?

I don't think that is a great idea because Audyssey sets the phase as well as frequency response. What you can do is place each MBM right next to each Trinity, this effectively makes them a single sub, then run Audyssey like that. Or you could use Audyssey for the Trinity subs, and then calibrate the MBMs manually, but that takes a bit more effort. Another thing you might try is using the sub out LFE signal for the Trinitys only and cross it over in the receiver's LFE to an appropriate point when using MBMs, which might be what, 50 hz?, and wire the left and right fronts though the MBMs, so from the receiver's perspective it sees your MBM+mains as a single speaker, and the Trinitys as the subs. To do that right you might want to use a high pass filter going from the MBM to the speaker, so Audyssey correctly sets the phase for everything, speakers, MBMs, and subs. I don't think it would be that hard to do, you would need one of these or something like this Hsu unit if you want higher quality and more contol.If it were me, I think I would do that.
