From what I've read that wouldn't be a problem. The only downfall is that you loose the punch that you would get from having it near field.
HSU recommends that the MBM be placed near field and the true Sub to be far field.
These are not set in stone. Dr. Hsu has stated that you can place the MBM between the mains or next to the True Sub.
If you have smaller sat's that don't go down below 80hz, then you have a dilemma or rather a choice of placing the MBM near field and risk localization (which depends on your taste, hearing a slight directionality from it doesn't bother me at all). Purists won't want to be able to localize the bass at all. ( reason being you would set the crossover higher than 80hz, most likely 100hz or 120hz to pair well with small sats.)
I'm running the MBM with a PC-Ultra and an Orb 5 speaker setup.
I'm crossing the MBM at 120hz (the orbs can be crossed at 80hz, but I'm going to give it a try at 120hz for a few days, 100hz and then 80hz.
The PC-Ultra in all cases will be handling 50hz on down, set in 16hz tune.
The beauty of the MBM is that it frees up some power on the Ultra since it will only be receiving the very Low LFE. Seems like it has even more punch now even though it had plenty of to spare even before introducing the MBM-12.
I have placed the MBM 12 behind the back left side ( if your back is facing the couch). It's a few feet from a corner in the room, my couch is a half circle shape.
The MBM port is facing away from the couch and towards the corner wall.
So far, I'm very impressed with the MBM and PC-Ultra combo. I haven't truly calibrated it yet with an SPL meter but I will in a week or so.
Just had to play with the gain on the MBM a bit, it's very sensitive and it does play the Mid-range loud if turned up to far. I only have it set just under 10 O'clock and it sounds great with a nice little rumble through the couch.
Crossed at 120hz, it is slightly locatable to my ears, but not enough to really bother me at all.
I will play with it some more and try lower crossovers and report back my opinions.
