Hello All I am new to the higher end electronics sceen and would welcome some opinions. I am wanting to purchase a HT system for my newly finished basement, but I have some challanges. Here is my proposed system: RB- 75 Fronts RC-7 Center Rw-12 sub R5800c - Rears Dennon 3805 Reciever My challange is that I only have 18 1/2" for a front speaker (The 75's ar 20.25"). The overall room is about 11 x 20, I dont mind spending the dollars for good imaging and a clear, detailed sound; but dont want chest pounding volume. The 35's are a close fit physically, but lack the sound quality of the 75 (my opinion only). Questions: If I lay the fronts on their sides would it really dimish the sound quality? Is this too much for my size room? Have any of you delt with Accoustic Sound Design? His prices are really low, maybe too low. If I cant make the 75's work I will probably go with the Polk LSI 9's - my second choice. Barry
