Wouldn't an H-Frame work 200Hz and down with the center also?
I see the problem you are talking about regarding the equipment rack and center OB speaker needing to occupy the same space. With a sealed or ported center channel the speaker can be placed either on or in the equipment rack. With the OB speaker the equipment rack would need to be off to one side. This would solve the space issue but require long runs for HDMI, speaker and interconnect cables.
Would a horizontal sealed or ported MMTMM version using 4 LGK's and a regular Neo3PDR be viable?
Or what about using an existing speaker like the N3S?
Or, since the Wedges are so crazy clean, clear and wide, what about setting the AVR for a phantom center channel and just using the mains?
