. It took me several years to design the crossover. The slope is as aggressive as it can be without smearing the frequencies in the time domain.
The amplitude frequency response is +/- 1dB, with a flat excess group delay over the entire audio range. Extremely complicated to do, any slight variation on either of the two plots, and the squarewave is no longer reproduced. Very few loudspeaker manufactures may accomplish this, but with only a first order crossover design. I can do it with a much more aggressive crossover.
I have pumped the drivers with 250 watts RMS per channel continuously over the years, and it has never damage nor blown any of the midrange or tweeter transducer drivers.
A very special crossover design. Further more, the speakers must be matched, in order to avoid creating any phase shift for the critical listener, such as I. Contact me at firstname.lastname@example.org for more info.
