Planars do need to be toed in perhaps a bit more to get that sweet spot. Mine are toed in so they cross a few inches in front of me. Plus that eliminates them from directly reflecting off the wall in back of them. Cannot tell you about diffusers, but I tried absorbers in back of them. What that did was it took away the spacious sound of the dipoles and most of the soundstage as well.
Planar Speakers and Diffusors
I have the Clarisys Speakers. They are the Planar type. I would like to treat the wall behind the speakers. I have been told not use any type of sound absorber, so I am interested in the GIK Acoustics Q7d Diffusor
I have a large 85" TV in between the speakers, so the only area that can be treated is behind the Planers. Check out my systems page.
I have yet to find a review of these diffusors, so has anyone used these and can comment on the effectiveness?
