I have a fairly large listening room, with around 5400 cubic feet, circa 150 cubic meters. It's an open floor plan so it isn't properly square or rectangular. I have hardwood floors and lots of other flat surfaces (I'll post some pics I posted in an old post later). I want to upgrade my Focal 807's, which I really like, but which aren't up to the task of filling that size room.
I'm quite open, I'm considering PSB Imagine T's, Klipsch, but I have dealers with KEF, Quadral, Magnat, B&W, and Paradigm. I have an Onkyo TX-NR708 which is nominal 180w/ch. It's 4 years old and I'm not to keen on getting some speakers that will be incredibly difficult to drive. I have a BK sub (the amp on which has started to hum the past six months or so), so the towers don't necessarily need to be bass beasts, although I wouldn't say no. I'm about 50/50 movies/music.
My budget is about USD 2k-2.5k. Would the Imagine T's be large enough to fill that space. Any other suggestions based on this criteria?
