RE: QRD diffuser, 1D or 2D best?

Posted by josh358 on November 23, 2012 at 16:39:17:
People usually use the 1-D QRD's. I'm not sure what would happen to the sound if you used the 2-D's. Line sources have as one of their advantages the ability to cancel out the floor and ceiling and approximate an infinite line source, so I've always figured it was best not to spray randomized reflections there. But this is purely speculative, I don't know of anyone who's tried it.
