Interesting waveguide measurements

Interesting indeed. Pattern control is a problem below 2-3.5 kHz in most of the combinations. Would have been good to see the behavior out to 30 kHz; most of theses waveguide/tweeter combo's I've played with have some reflections in the mouth which cause some irregularity in the 18-24 kHz area. A function of mouth size; it doesn't show up with a true compression driver and waveguide like the BMS4540 and DDS ENG1.

Besides irregularities those WG don´t have constant directivity properties. Does the small amount of on-axis response lift in say 8k+ region helps to smooth power response? Can you tell me how wide horizontal angle is reasonable to take into account for design?

New stuff from this guy, no tweeters this time though! :B
