The PSB Imagine X2T towers seem made-to-order for your situation. They're $1298/pair, reasonably sensitive, have fairly wide, room-filling dispersion, and deep, strong, fast bass, a necessity for energizing large listening spaces.
Crutchfield's user reviews are very favorable, and some make a point of how well they work in large spaces and how deep and driving the bass goes.
They're also an Absolute Sound GoldenEar choice.
