Illuminati (33rd Degree)

The seven π crossover points are 250Hz and 1.6kHz. The lower crossover is very gradual with a lot of overlap so the midrange goes deeper than that. The woofer is rolled off slowly and is at half power at 250Hz. The upper crossover is steeper and asymmetrical. It was designed to provide perfect summing between the midhorn and tweeter.
