Nice room! It looks like an upscale chinese restaurant, very cool.
Duke,
Thanks for describing your thought process considering a suitable bass solution for imdoc's somewhat unusual room.
I understand your reasoning for suggesting a powerful pair of subs instead of a 3-4 sub array. Hopefully, imdoc can find a pair that blends well with his Maggies and can position them well enough to reduce standing waves and give good bass response at all the dining positions.
Later,
Tim
