Wayne, I might be saying the same thing in a different way, but I find it easier to understand in terms of off-axis response. For good overall in-room response, you're looking for a speaker with not just smooth on-axis, but also smooth off-axis response. Uniform DI would accomplish that.I forget for the percentage is, but the large majority of what we hear in-room is reflected sound and a lot of that comes from first reflection of the speaker's off-axis response.
