for those who don't know, a primary goal in this kind of design is to get each off axis frequency response plot to be parallel with the one above it. if they are all parallel, then one can use equalization to change the 'power response' of the speaker equally and everywhere.
noah, horn width may be the factor for which you are looking. the conical holds pattern to a lower frequency with a wider horn and a smaller, if any roundover. the horn here has a large roundover, so has less width to hold pattern control. that said, the lines are all pretty much parallel so you can eq it however you like! well, let's say down to 1khz or so. ;-) the horn doesn't appear to give up the ghost until just under 900hz.
jza, and all others who helped bring this one from a dream into a finished product (and extra props to erich for helping this along)...ABSOLUTELY AMAZING WORK GUYS!!! this is a home run. this is a f_cking home run! it should be a great match for either a 12" or 15" driver. folks will want to know how they can get in on the action...does this work with the econowave deluxe crossover or something like that. the b&c driver, the jza/avs-community horn, now there needs to be an enclosure (flat pack erich?), a woof and a dividing network...maybe wayne can rejigger the crossover on the 4pi optimized to go toe to toe with the geddes summa. so many options, i hope that one of them comes through...
absolutely massive props again guys...you did it!
[for the grand slam, 18" seos, 1.5" throat, bms 4555 ;-), but that'll come later]
