In designing the crossover, I wanted to try to keep the parts count relatively small while taking advantage of the natural performance of each driver. By measuring the driver responses and using Soundeasy to model the crossover, I ended up with a crossover point of about 600 Hz between the woofer and midrange, and about 5 kHz between the midrange and the tweeter. Allowing the midrange to cover a fairly wide bandwidth enables a somewhat less-complex crossover, while at the same time providing great upper midrange clarity. All drivers are wired in the positive polarity, which just happens to yield the best response and phase coherency around the crossover points in this design. Note that the frequency response measurements show a dip around 2k, which is actually a result of the non-flush-mounting of the midrange. This dip quickly goes away off-axis, and as such, these speakers may best be used without "toe in" of the cabinets.
