I had the 1.7's in two different rooms, one larger and one smaller than yours. In the smaller 13x15' room, they were nearly half way out into the room and I sat right against the rear wall. Great imaging with bass reinforcement. In the larger room room they were roughly 1/3 out from the front wall, I sat 2/3 from the front wall. Equilateral triangle arrangement. Worked very well also. The critical thing is getting them off of the front wall (the front wall is the wall you look at)
I doubt you will be lacking for power nor do I think you need esoteric cable to get fine results--I used Supra Rondo 4x4.0.
