I just had a quick question on how to set your speaker distances on your receiver. Does this actually make a difference? Let's say for example, someone has a smaller room, and are seated very closely to the front speakers as well as the rears. Could they get better effects if they told the receiver the rears were farther away than they actually were and vice versa with the fronts? I set my receiver up with the fronts being 10 feet away and the rears 4 feet away (which is exact) but what would happen if i said the fronts were 4 and the rears were 10? Would the effects and loudness change?
