Minimizing interference effects in Tweeters and Tweeter-Woofer combinations

Point-source vs large-area tweeters are analyzed in terms of phase interference. Theoretical analysis shows that the desired upper frequency limit as well as the dispersion angle place a limit on the maximum dimension of a tweeter diaphragm. Also, phase interference is analyzed in the crossover region in woofer-tweeter combinations. This interference is shown to be a function of the physical displacement of the woofer diaphragm with respect to that of the tweeter. Theoretical findings are substantiated with experimental results.
