I currently own a VTF-3 MK3 and just purchased a MBM-12. My room size is 22' X 20' X 9. I had the MK3 9 feet to the 'left/rear' of the listening position and really enjoyed the couch-shaking LFE.
Now, the MBM is located in that position and the MK3 is in the 'front/right' corner of the the room, 17 feet from listening position. Is this an optimal setup for my situation, or is it possible to switch the MK3 back to a near-field position and the MBM in the front/right corner? Thank you.
