Soundhound,

I have been advised by some that the highpass and lowpass poles be staggered a half octave to ameliorate an "in phase notch". I am thinking that there are "real world" inefficiencies given the different drivers and electronics that results in less than a unity in the crossover octave. But I am also thinking that if the frequencies are staggered, there should be an additive amplitudinal change (a spike rather than a notch) in the doubled over region. What is your opinion on this?

I am just bouncing ideas at you before I order more frequency modules. I have not had a chance to measure the speaker output as a whole yet. I've only worked on individual drivers so far with truRTA.
