Speakers VERY close to wall - Cork board useful?


Hi there,

I have a set of Klipsch RP-5's, that have a built in powered sub, and a rear facing port on the bottom of each tower. I have them in a small room (15'x13') with about 6' of separation. Considering the small room dimensions I have them pushed up against the wall because otherwise they'd be in the way. They are at least at a slight angle, but the port for the sub is still only about 4" off the wall. 

Would putting a square of cork board on the wall directly behind the port, cut out so its slightly larger than the port, make any positive difference compared to an ordinary sheetrock wall?  (The cork comes in a roll, so it is maybe 1/8" thick)

Any thoughts, additional suggestions on other common house-hold materials/geometry of cut/ etc, or comments would be appreciated! (other than "move the speakers away from wall" bc unfortunately that's not an option in this room)

:)
thanks!!!

I had a similar situation and found there's really no substitute for breathing room for speakers unless they're built to work that way, especially if you're concerned with soundstageing and imaging.  So here's what I did -- when I wanted to listen critically I pulled the speakers a few feet into the room and pushed them back when done.  There are probably lots of aftermarket footer options that would let you easily slide the speakers back and forth without damaging the floor or significantly compromising sound quality.  Hope this helps and best of luck. 

In addition to Yakbob's recommendations I'd add Sjofn The Clue.  I think they offer a free in-home trial.  BTW, don't pay any at attention to the Stereophile review of them.  It was completely botched and they should be ashamed of themselves.  Everyone who's heard them at shows (including me) has been amazed.  If you can afford a stacked pair do that.  Really incredible.
