Hello, I am a super newbie with this stuff! I just purchased am RCA RT2870. My receiver is in a cabinet in the rear of the room, not in the front of the room, so it would be advantageous to switch the front/rear speaker placement as the rear speakers have longer wiring, thus putting them in the front (the farthest from the receiver) would allow me to use less extra wiring. Will this mess up the sound? Are the speakers pre-tuned to be front/rear speakers, or is all that work done by the receiver and determined by which input the speaker is connected to? I.E. are the front/rear differences coded into the speaker or the receiver? Thank you for your help!
