Crossover Frequency
Crossover frequency identifies the transition point between frequency bands handled by a crossover.
The value is in hertz. A multi-way system can have several transition points; a variable or selectable range describes available settings rather than one fixed point.
Crossover Frequency — Loudspeaker
For a loudspeaker, crossover frequencies identify handovers between driver bands, such as bass to midrange and midrange to treble. The drivers still overlap through each transition region.
Keep all stated points for a multi-way design. Crossover frequency is different from port tuning or a driver’s resonance, and it does not describe the crossover slope or the finished acoustic response by itself.
Crossover Frequency — Super Tweeter
For a super tweeter, the frequency describes its high-pass transition into the main loudspeaker’s upper range. A fixed, selectable or recommended value must retain that qualifier.
Compare the frequency with the specified filter and integration requirements. A minimum recommended crossover is not a freely adjustable setting, and the driver’s acoustic cutoff is a different specification.
Crossover Frequency — Crossover
For an active crossover, the frequencies set the boundaries of the output bands feeding separate amplifier or driver paths. Different branches can have independent settings.
Compare the available range or selected points together with slope and alignment. Frequency alone does not establish how the outputs sum, and an equalizer’s centre frequency is a different control.
Crossover Frequency — Subwoofer
For a subwoofer, the value describes its own low-pass transition toward the main speakers. It can be fixed, adjustable or bypassed in a specified operating mode.
Distinguish this filter from bass management elsewhere in the system. A satellite-output high-pass or enclosure tuning frequency is a separate property, and the best combined response depends on the main speakers and placement.
