Features

Enclosure Simulation

• Sealed and vented (bass reflex) enclosures
• Real-time frequency response (SPL)
• Cone excursion modelling
• Port air velocity modelling

Graphs available:

• SPL
• Cone excursion
• Port velocity
• Cone velocity
• Port volume velocity
• Phase
• Impedance (electrical)

Driver Management

• Built-in library (85+ drivers across major manufacturers)
• Import WinISD .wdr files
• Search and filtering by key parameters (size, impedance, Fs, Qts, Vas, power, brand/model)

Comparison Workflow

• Multiple enclosures side-by-side
• Multiple driver configurations per enclosure
• Per-configuration visibility toggles
• Color-coded plots and grouped legend

Enclosure Configuration

• Box volume control (1–1000 L)
• Vented tuning frequency control (15–100 Hz)
• Port modelling:
  • Diameter control (25–300 mm)
  • Automatic port length calculation
  • End correction settings
  • Multiple ports support

Simulation Environment

• Input power control (0.1 W–10 kW)
• Radiation space selection:
  • Full space (4π)
  • Half space (2π, default)
  • Quarter space (π)
  • Eighth space (π/2)

UI

• Responsive layout (desktop, tablet, mobile)
• Collapsible left and right sidebars with resize on desktop
• Multi-graph selection and two-column graph grid

Technical notes

Uses a lumped-parameter electro-mechanical-acoustic network model intended for low-frequency enclosure design (sealed and bass reflex).

Not intended for horns, complex geometries, or non-linear behaviour modelling.
