graphed Eminence CD-8 on Peavey CH-2 - mic may have been too close as it showed very level/smooth FR to 12.5Khz rolloff point both on and ~20 degrees off axis - 'ears' say its subjectively dull/unbalanced compared to 'old school' horn

when using w. typical 97-99dB 15" direct radiator - what might be workable cap bypassed series pad starting point? - didn't have much luck trying a couple of value caps across series leg of L-pad although Peavey horn designer suggested that method
