Re: How to Design Loudspeakers without Performing Measurements
Absolutely right Charlie. I didn't get into that level of design detail in the presentation as it was meant as a tool training aid, not a design tutorial. We could fill many pages herein discussing that topic. 
FWIW, in design, I put most importance on the direct axis response, followed by the response at the angle that corresponds to the first side wall reflection, followed by the angle that corresponds to the floor bounce, followed by a general +/- 45 deg "wellness" view. Dips are relatively OK, peaks, not so much.
One other thing i need to stress is that it's important to do a good job on the diffraction modeling and splicing. Changes in <150Hz level relative to 1 kHz of even 1 dB has a profound effect on the tonal balance. Thin and brittle results from too soft a mid bass.
