The system will be used primarily for movies 85%, the balance as radio/cd. The room size is 14 x 19 with only three walls and open to large kitchen area. The ceilings are high (vaulted). I have looked at PSB speakers - B25 (L/R channel) and maybe the T45 or 55 as mains with the complimentary center channel. The second set-up would use Revel products F12, M20 and center. Can a receiver be used to bi-wire these speakers?
