The Circuit in general
This is my prototype circuit. Since the design is currently
just a paper project (as of May 10, 1998), I will not waste time with long-winded
remarks about it. Here is the schematic.
It should end up with a quasi-3rd order acoustic crossover at 2,000hz with
the drivers slightly more than 68 degrees out of phase at the crossover
point. However, I may add a phase correction circuit to the high-pass which
will increase the phase into the 90 degree range. This should both flatten
the crossover point and create a more symmetrical vertical dispersion.
Here is the circuit topology. I also have added a bass limiting capacitor
with a bypass switch to the woofer's ciruit. It is a 250 uf electrolytic
capacitor coupled with a 25uf poly. capacitor. The switch is a SPST which
simply circumvents the coupled-capacitor.
