Getting Started

KFilter6 uses a project-oriented workflow with up to four driver slots.

1. Create or open a project

Start KFilter6 and create a new project or open an existing .kfp file.

Legacy text-based KFilter project files can still be opened. New saves use the current versioned JSON project format.

2. Configure the drivers

Open:

Edit -> Driver Parameters...

Enter the relevant Thiele/Small and electrical parameters and configure the enclosure values. Each driver can also have its own gain, polarity, curve visibility and summation settings.

3. Edit the passive crossover

Use the network-parameter editor or click directly on the corresponding R/C/L section in the graphical Network Preview.

Each driver contains eight passive network sections.

4. Add optional response-processing stages

Depending on the project, you can add:

  • an Active Filter chain
  • Baffle / Diffraction processing
  • experimental Floor Reflection processing
  • imported Measurement correction

The Network Preview contains direct interaction areas for several of these functions.

5. Inspect the result

Use the plots to compare:

  • individual driver SPL
  • vector SPL sum
  • energetic SPL sum
  • individual driver impedance
  • total impedance

Around crossover regions, compare vector and energetic summation to understand the effect of relative phase.

6. Save or export

Save the project as .kfp.

You can also:

  • import/export complete driver slots as .kfd
  • export stored relative correction data as FRD
  • export the project overview as PDF

Development status

KFilter6 remains under active development. Project format versioning and transactional loading are already implemented, but workflows and user-interface details may still evolve.
