It's less than half the size of your grazing space (4,200 ft^3). It's open to the rest of the house via a staircase so I do lose some sound pressure.

I used to sit 8' away from the M80s on the diagonal but I've re-arranged the room and I am now 14' away which has made the soundstage unbelievable. Model Ts or LFR1100s would fit right in to this space for sure.
