Version 0.4.0

January 13, 2026

Overview

Major release bringing passive radiator support, link sharing, and significant bug fixes for multi-driver configurations.

New Features

Passive Radiator Enclosures 🔊

A new enclosure type! Passive radiators (PRs) offer an alternative to ported designs with some unique advantages:

• PR Support: Select "PR" as an enclosure type and choose from the passive radiator database
• Multiple PRs: Configure multiple passive radiators per enclosure with combined parameters
• PR Excursion Graph: Dedicated graph showing passive radiator excursion limits
• Accurate Simulation: Full acoustic impedance modeling of the PR mechanical system

Passive radiators can achieve lower tuning frequencies than ports in compact enclosures, and eliminate port noise issues.

Link Sharing 🔗

Share your enclosure designs with others:

• Create Share Links: Click "Share Link" to generate a shareable URL
• Select What to Share: Choose which enclosures, driver configurations, and graphs to include
• Customizable Notes: Add a name and description that recipients will see
• Import Shared Designs: Open shared links and import configurations to your own simulator
• Human-Readable URLs: Share links include driver and enclosure info for easy identification

Bug Fixes

Multiple Driver Simulation 🔧

Fixed simulation calculations for multiple identical drivers:

• Corrected acoustic coupling calculations (was showing N² over-coupling error)
• Share page now uses the same simulation approach as the main page
• Proper power distribution per driver in network solver

Improvements

UI/UX Enhancements ✨

• Context Menus: Enclosures and driver configurations now have a 3-dot menu on hover with Rename, Duplicate, and Delete options
• Sealed Box Fsc: System resonance frequency (Fsc) now displayed for sealed enclosures
• Independent Panel Scrolling: Left and right panels now scroll independently from the central graphs
• Graph State Persistence: Selected graphs and expanded/collapsed state now persist across page refreshes
• Improved Share Page Layout: Better organization with notes, power input, and simulation summary
• Error Handling: Graceful error states on share pages with helpful messages
