Going to go with pair of HSU VTF-15H MK2s. Will be placing them on their side under the screen. Most likely next year will be LCR upgrade time so may end up moving them if I decide to go with bookshelves instead of towers on the sides of the screen. But for now, will use 1/4,3/4 placement and see how things go. According to my room modes...I am good in terms of where my seats/rows are.
Looking forward to setting them up. Already started prepping....MiniDSP , long cables, etc.
My suggestion... order 1. When you get it, place it on both sides of the CC and measure the response. If both responses are very similar, then adding a second will only net you more output, not smoother, more consistent frequency response across more seats. Why...
When 2 subs are placed close together, the "mutually couple." Their wavefronts couple, combine and propagate as ONE wavefront with higher SPL. In other words, you only get ONE frequency response to work with. You do get more headroom, but the FR will be only slightly impacted, if at all.
To get frequency response smoothing, you need more than one frequency response to work with. That way, where one sub has a dip, the other will likely have a peak, and vice-versa, and the two will smooth each other out. Placing the subs on either side of the CC will not get you that. If you can't spread the subs further apart, you may be better off just getting one "better" subwoofer. Then EQ it for your primary listening position, and accept whatever response you get at the other seats.
