I have seen so-called "2.1 way" systems where, if I understood right, the formulas for a basic 2 way crossover are used, but multiple low frequency drivers are used, each with their own lowpass crossover and frequency. What I'm wondering is if I can, using the standard formulas for a 3 way crossover, do a similar thing. I.e., design the bandpass section normally, but have multiple lowpass and/or highpass frequencies...would that work, at least in terms of the crossover dividing the audo as designed?
For that matter, what if one wanted to use multiple bandpass units? I realize that each bandpass crossover must have the standard 3 or 3.4 octave spread but, if you have more than one within the same system, they will happily work as designed, independently of each other, right?
If anybody is wondering, I'm only thinking of doing some experimentation with some of the numerous, oddball drivers I have laying around, gathering dust and, thus, thought I would try something different... I always prefer, if possible, to avoid wasting time and find out in advance if somebody out there already knows that my brainstorms won't work.
