Ceiling QRD Diffuser
I think this is the best subforum for my post. I've been considering all kinds of different options on mounting my soon to be built ceiling speakers for my soon to be built house with a media room. After finishing Toole's book last week, I've been considering a new option. He recommends a diffuser on the ceiling.
As I work on a possible plan for a 1D QRD diffuser between the left and right speakers on the ceiling, what is the advantage of repeating a smaller N number vs building a large N number diffuser? I could just as easily build the larger number N diffuser in multiple panels sharing well walls just like a series of the same smaller pattern. Which would you say is the most advantageous?
