How can you tell if one diffusion product is better or worse than another product?
Should one look at certain measurements across the frequency spectrum?
Are there rules of thumb, such as surface area covered? Depth of grooves in the product? Variations in the grooves?
Are all materials the same, such as foam, wood, polyestyrene? How does the choice of materials impact quality vs. geometry of the product?
