Selectable Crossover Slope
Selectable Crossover Slope describes the available settings for how steeply a crossover filter reduces frequencies beyond its transition region.
Slope is commonly expressed in decibels per octave. An octave is a doubling or halving of frequency. A steeper low-pass slope reduces higher frequencies more rapidly, but the stated slope does not describe the entire response around the crossover point.
Selectable Crossover Slope — Subwoofer
The setting affects how the subwoofer’s output overlaps with the main speakers. Compare it alongside crossover frequency, the main speakers’ natural roll-off or high-pass filter, and the listening position. A steeper setting is not automatically a better blend; the combined acoustic response is what matters.
Check which slopes are actually selectable and whether an LFE or bypass mode disables the filter. A single fixed-slope specification does not prove adjustability. Electrical filter slope and acoustic roll-off can differ because the driver and enclosure also shape the result, so do not treat a control setting as a measured room response.
