Has anyone used the rp-140SA's as surrounds? I currently have RP-280f's front channels, RP-450C Center, and a R-112SW sub. I would really like to pair the RP-250s with this setup, but my room has limited me. The surrounds will have to go between a closet door and the rear wall with only about 2ft clearance. I was hoping the 140SA would work well there, but would like some opinions. Also, since the are angled, should I mount them up high? Thank you so much!!!
