I'm interested in getting a pair of RB-5II's to act as mains; however, I'm wondering about the impact of speaker placement on their sound. They will be sitting atop shelves and placed almost directly against the wall. I have very little, if any, room to move them away from the wall. Most of their use will be for Movies/TV in conjunction with a subwoofer (probably crossed over at 80Hz). Can anyone who has these speakers let me know if placing them so close to a wall will have much of an impact on how they sound?
