Lots of constraints in this room. A long and narrow room (15 x 30) that doubles as a dining room and living room. Lots of openings, so speaker placement was limited. Original goal of this system was mostly for background music while dining or entertaining with guests - but it's continued to evolve into much more.
Very happy with the Bryston Mini T's. Only 23 inches tall, they have excellent base extension, and they sound good from just about anywhere in the room.
Your setup looks quite nice to me. I like how the Yamaha fits into the credenza, too. Just make sure guests don't set their drinks on top of the speakers!
