Specifically looking for a diffuser rather than an absorber behind the speakers to help widen the soundstage yet still address the comb filtering from the rear wave.  Something like this - http://gikacoustics.com/product/gik-acoustics-q7d-diffusor/

Ok so does that mean I move the bass traps to a different location to make room for the QRD? or just put QRD next to the existing bass traps?

Put it next to the corner trap.

here are some pics. Not there is not a lot of room next to the right speaker (12 in) on left side there is 16 inch.

Perhaps others could comment but I'm not sure I see the purpose of the absorber on the left wall (which seems to cover mostly an open area), the diffusers above the woodwork all round, and even most of the diffusers on the ceiling (I can see the possible need for two panels say).

Could these items not be used best elsewhere?

The absorber near the left speaker is in actuality covering more of the low book case rather than the open area. (I was a little bit off in the positioning) But I agree it doesn't seem to do anything. because of the carpeting and the acoustic ceiling tile the room had a "dead" sound to it. I wanted it to be more lively so I was advised to use diffusors on the ceiling and absorbers at the first reflection points on the walls.
