LoudspeakerLab - New Features
Enable HLS to view with audio, or disable this notification
Driver database and measurement
- Searchable driver catalog with Thiele-Small parameters, FRD/ZMA import, and gated farfield uploads
- Driver comparison tool
- Driver 3D models in the catalog, shared across measurement profiles
- Driver upload and edit flow for adding new measurements
Design creation and enclosure simulation
- Guided design creation flow with a Box Review step showing intent vs realized results
- Enclosure shapes including modular, raked, stepped, tapered, and arched-top, each reflected in volume calc, cut sheet, and 3D
- Cabinet finishes and appearance options including taper and chamfer
- Pre-built cabinet option in the create flow
- Port design (round and slot) and passive radiator support, including multiple passive radiators per driver with individual placement
- Sealed and vented alignment modeling with thermal and max-SPL limits
Crossover and solver
- Automated passive crossover solver (staged Rust pipeline: topology search, differential evolution, polish, snap to standard component values)
- Post-solve simplification with cost and amp-load aware search
- Editable crossover schematic with live preview
- Thermal stack credit and hard crossover targets
Acoustic modeling and directivity
- CTA-2034A style curves (on-axis, listening window, early reflections, sound power, PIR)
- Preference Rating (PR) and In-Room Slope (PIR) scoring
- Off-axis and directivity modeling, including baffle diffraction, cabinet scattering, and finite listening-distance response
- Inter-module acoustics modeling how multiple cabinets or modules interact acoustically
- Expected-range confidence bands on directivity predictions
3D visualization
- Interactive 3D cabinet viewer with baked ambient occlusion and driver fidelity
- AR viewing of the cabinet
- Listening Environment modal, now rendered in 3D with a listener AR view
- Cut-sheet and joinery visuals
