Overview

This release adds support for dual voice coil (DVC) drivers with configurable series/parallel wiring options, allowing accurate simulation of popular DVC subwoofers like the Dayton Audio Ultimax series.

New Features

Dual Voice Coil (DVC) Support

Suggested by r/Slurp6773

• Automatic DVC Detection: Drivers with multiple voice coils (numVC > 1) are automatically detected from WDR files
• Wiring Configuration: When a DVC driver is selected, choose between series and parallel wiring in the driver configuration panel
• Effective Impedance Display: See the calculated effective impedance (Re) based on your wiring choice
  • Series wiring: Uses the stored/datasheet Re value unchanged
  • Parallel wiring: Re ÷ numVC² (e.g., 4.3Ω series → 1.075Ω parallel for 2 coils)
• Accurate Simulation: The simulation uses effective Re and Le values for all calculations, including SPL, excursion, impedance, and power handling

Driver Form Improvements

• Voice Coil Count: Added "Voice Coils" field to the driver parameters editor for creating custom DVC drivers
• Renamed Button: "Edit T/S" button renamed to "Edit" for clarity since the editor handles more than just T/S parameters

Bug Fixes

• Fixed issue where editing voice coil count and saving would not persist the change
• Driver edit form now properly reinitializes when reopened with updated driver data

Technical Details

• Wiring configuration is stored per-configuration, allowing comparison of the same DVC driver with different wirings
• Driver T/S parameters (Re, Le, Bl) are stored as series-connected values (the default/datasheet configuration)
• Series wiring: Uses stored values unchanged
• Parallel wiring (conversion from series):
  • Re = Re_series ÷ numVC² (e.g., 4.3Ω → 1.075Ω for 2 coils)
  • Le = Le_series ÷ numVC²
  • Bl = Bl_series ÷ numVC
• For the same input power, both wiring configurations produce equivalent acoustic output (verified against WinISD)
• Default wiring is series when not specified
• Share links now include voice coil wiring settings
