Curious why 2-3" for down to 120Hz, as opposed to breaking you your array down into a few more cone sizes for more bands, like say, some 8" for low 100s of Hz,

Curious why 2-3" for down to 120Hz, as opposed to breaking you your array down into a few more cone sizes for more bands, like say, some 8" for low 100s of Hz, and a 3" for high 100s of Hz into low 1000s of Hz before the tweeters take over. Or is your goal to minimize the complexity of the crossover network that would be needed to cleanly separate the the bands with minimal distortion and the "fun" of correctly lining up the physical phases of each of the different cones?
