I think the crossover is a first order lowpass for the midbass (1 inductor). For the highpass to the tweeter, it is a first order (1 capacitor) with some attenuation (1 resistor).
Thanks... I can see it now in the installation documents. The new 268 crossover have a single tweeter output regardless of OEM sound system (Business or Professional). The 684 crossover has two different tweeter outputs, one for Business and one for Professional systems.
