Illuminati (33rd Degree)

Crossover frequencies are 250Hz and 1.6kHz. But the midhorn/woofer crossover has wide overlap, so the midhorn really goes down to about 150Hz and the woofer and midrange share the lowest midrange octave. They're within 1/4λ so they sum as a single acoustic source. The midrange/tweeter crossover is also not really something that can be described with a single number because the crossover is asymmetrical, depending as much on acoustical slope as electrical. Midrange/tweeter crossover happens between 1.2kHz and 1.6kHz.
