Passive Crossover

Each KFilter6 driver has eight passive crossover sections.

Section structure

Every section contains:

Series branch: R, C, L
Shunt branch:  R, C, L

KFilter6 preserves the established crossover-network mathematics of the original application while presenting the network through a structured Qt6 interface.

Internally the network is held as a structured eight-section model; the historical flat list of 48 values exists only at the serialization boundary of the project and driver files.

Each page of the Network / Filter Parameters dialog names the driver it edits below the section table, so it stays clear which slot is being changed when several tabs carry similar values. Unnamed slots fall back to Driver 1 … Driver 4.

Network Preview

The graphical Network Preview is both a schematic and an interaction surface.

It can display:

  • all four drivers
  • an individual driver
  • passive section values
  • driver state
  • compact active-filter information
  • acoustic/baffle access points

The R/C/L groups can be clicked directly to edit a specific section. The driver/enclosure region opens the matching Driver Parameters tab, the Active Filter strip opens the active-filter dialog, and the radiation-wave symbol opens Baffle / Diffraction parameters.

Curves and totals

Per-driver plot state controls whether a driver participates in:

  • SPL display
  • impedance display
  • vector SPL sum
  • energetic SPL sum
  • total impedance

Polarity inversion and the full crossover simulation path are also configurable per driver.
