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 think all cork will do is eat up more valuable real estate back there. 

The vents look like a good idea.

I have relocated ports, cutting out frontal ports with a hole saw. Then sealed the rear cavities. I got the same sized ports from a parts supplier that have over hanging flanges for easy installation. Plus they hid the rough cuts and small chips created by the saw. The side mounted bass may work to an advantage as to not challenge the speaker's over all design much, or at all. More true if the internal cavity is symmetrical. But I'm not suggesting anyone go hacking into there factory speakers.  

Footers for easy movement sounds like a good option. But wont help for decoupling. For carpet footers made of rounded over walnut or other choice with a high count sandpaper polish. Even hit them with some wax. This made a 150 + lb audio rack a breeze to slide away from the wall to make adjustments or dust. Then when I had it placed on a hardwood surface I simply stuck felt pads under them.

Some bass traps in the L\R and top corner should further help the situation.
