Ahh that makes more sense.
Did you keep the same crossover point or did you lower the crossover point to work better with the boost? I have seen where boost at the crossover can be problematic.
Here's my final measurements, the response is not accurate from about 300hz down, the f3 is actually in the low 30's

Thanks Tom. These are my SDC entry into the Dayton class. In the past there have been a limited number of cheaper entries into this class, because guy's have entered the under $xxx class, the thought being that in the Dayton class you will have to go up against expensive drivers and in the under $ class that won't be the case. The last time I checked, these have about $186 in drivers, so I'm bringing a knife to a gun fight, but it's about fun for me.
I forgot to mention that the response isn't accurate from about 300hz down. I got lazy and didn't splice the close woofer measurements to all the lines. The f3 is in the low 30's, I'll post the bass response when I get a chance.
Another very good design, Nick! Those verticals look really smooth for a speaker with a very high xover point (3.5kHz-4kHz or so). I'm guessing, but looks like about 2" ctr-to-ctr spacing distance from tweeter to mid?
Bill, the c-t-c is about 2-1/8" and the crossover point is approximately 3150hz. I can get away with that low of a crossover only because the wg provides low end boost.

Very similar crossover point, but different slopes.
I made some grills to cover the woofers, even though there's nothing wrong with an ugly woofer.

Hot damn!!!
Your technical skill and craftsmanship is amazing. PE should give you an award for making their drivers perform so well!

Drivers alone only get you so far. You've done a great job with these both visually and acoustically.

Totally bitchin Nick!

This is the blank cover that I made out of 1/8 aluminum to replace the passive radiator that was no longer needed.
