Forgot to add, this is two MCM 4" woofers crossed to an AV123 tweeter at around 2500 Hz with a first order crossover- one cap and one coil. The tweeter drop off is so steep that it is down around 16 dB at the crossover point, so unless the girls that built it play it at big room party volumes, it should do just fine. I suggested a few tweaks that might clean up some of the ripples above 2K. I think we are going to have a tight competition this year with nearly all the projects measuring quite nicely!
