I'm calling this the cheapowave as it is using the econowave concept (PA horn for hifi) but I am using a much cheaper compression driver than the one specced in the econowave spec - but the results should be really good anyway.
for comparison Mission Model 77 speaker measured with the same setup, no sub

crossover attempt.. not a focussed design due to changing parts at the last minute.
-> 3rd order low pass
-> 2nd order high pass with notch filter
-> horn too quiet, still too many bumps in woofer response

better measurement of the PDS221 comp driver with ph612 horn
has 33 uF capacitor for protection. 1M away, ARTA impulse response, imported into Speaker Workshop, then smoothed.

First successful crossover..
variation of the Econowave crossover, but with the lowpass set to be first order to taper off the some of the bumps in the pioneers output, and the HP values tweaked to compensate for the Pyle PDS221 rolloff..
