That horn is an exponential. You'll be missing one of the defining principles of eWave -- constant directivity. Get the right waveguides.... :yes:
If all you want to do is measure response, FuzzMeasure will do that on Mac, according to Skywave. Upgrade to full functionality is $150, tho.

You should be able to find a used PC for that, and HOLMImpulse is free....

Just ask around. More than a few folks have a functional windows box that they will give to someone that will use it. Of course you will have to suffer the indignity of admitting that an obsolete PC is better than your Mac:yes:

Still listening to the Ewaved DQ-10s with DE250/QSC and refoamed Advent woofers. So far no angry mobs have laid siege to the house for my disrespect of The World's One Perfect Speaker. This sounds outstanding. I may actually resist the people who keep asking 'What are you going to do with those when you're done?" These could be real keepers, although I always say that. I'm using the stock ewave XO and holding off on final XO fabrication until the brains have sussed out the details.
I haven't touched a speaker project in 10 days. I'm still buried in the chip amp project article with 4 days to go until deadline. So much metal to cut, so little time. I Ncase anyone wonders why I don't answer the phone, I assembled a PCB the size of a business card with 30 components, 75 solder joints, 12 jumpers and one serious mistake that made it explode. All because I took a call at the bench and got a polarity wrong. Blew 6 hours' work. So I'll be scarce until Tuesday.
Okay, so a rough measure showed 1.5 and 1.2 dB of reduction on the twin peaks at around 1300 and 2600 respectively, and a smoother trending behavior resulted. For some installs with a highly refined lowpass and smooth response through the crossover, it might create an on-axis dip.
See the current state of mine- in the throat there is a wedge of 30 ppi reticulated foam (a la geddes) and the outside "foam frame" is made of open-cell laptop packing foam. The idea, naturally, is to damp edge diffraction of the mouth, and this is accomplished both by the beveled profile and the lossy nature of the foam.
I'll try to get measures up soonish but I'm still working on XO optimization.
PRX is the JBL horn from MRX/PRX series.
Pyle calls the PH-612 "constant radiation," and I consider their operative description of what that means to be synonymous with constant directivity. I suspect it was part of an agreement for them to sell them that they not call them what they are, or, if there was no agreement, part of a rationale for arguing non-infringement, should the necessity arise.
Edit: Back to basics, now:
Standard eWave w/DC300-8 front-mounted in 30 Hz vented KDT, ~$400 a pair the complete kit.... :yes:
