Frequently Asked Questions

A passive crossover uses capacitors, inductors, and resistors to divide the audio signal into frequency bands for each driver without external power.

Select frequencies based on driver response ranges, speaker design, and desired tonal balance.

Common slopes are 12 dB/octave for smooth roll-off. Higher slopes increase separation but require precise components.

Yes, input midrange frequency and select 3-way. Components for all drivers will be calculated.

The calculator rounds to common standard values for capacitors and inductors wherever possible.
