I have the Klipsch KSW-12 hooked up to my Denon AVR-3801 as follows:
A 1-male to 2-female Y Adapter on the sub pre-out of my receiver, to a 12 ft. stereo RCA patch cable that plugs into the left and right low level inputs on my sub.
The question I have is this:
Should I run 1 mono RCA patch cord from the receiver pre-out to the sub, and then use a Y adapter (1-female to 2-male) into the L & R inputs on the sub? Is there a difference? The reason I ask, as this is almost like bi-wiring my sub and I am wondering if I am losing signal, or giving the sub more signal by using 2 totally separate patch cords to the sub.
Also, how far would you recommend placing the rear port from the wall. I know I need to move it where it sounds best, but isn't there a rule of thumb that the port opening should be so far from the wall to allow the air to escape freely?
As a side note, I have RB-5's in the front, RC-3 in the center and RCW-3 in the rear. The RB-5's and the RC-3 are on top of my TV and rack (I have a Mitsubishi 60" TV with a matching rack - so they are pretty spread out), and I will be adding a shelf above my TV later that will house all of the speakers and increase the space between them.
One last question, on the RC-3 (I know this is the sub section of the site - but might as well knock em all out at once) - do you need to put that 5th rubber foot on the bottom to cover the spike hole? Is it really open all the way into the enclosure? I didn't know you had to do this, as the manual that came with the RC-3 didn't mention this at all, but the manual that came with my RB-5s (a new and much improved manual) mentioned it.
Any info would be appreciated.
