00 Loudspeaker Enclosure Simulator
A browser-based enclosure simulator for sealed and bass reflex boxes.
What it does
- •Sealed and vented simulations using a small-signal Thiele-Small model
- •SPL, Max SPL (thermal vs excursion limited), excursion, impedance/phase, and port velocity plots
- •Add drivers by entering T/S parameters, or import WinISD .wdr files
- •Compare multiple drivers and enclosures side-by-side
- •Per-driver filter chain (PEQ plus high-pass/low-pass)
- •Input power and radiation space options (full, half, quarter, eighth)
How it works
The simulator uses a standard lumped-parameter T/S model and solves the coupled electrical, mechanical, and acoustic impedances per frequency to estimate response at 1 m. It's aimed at low-frequency enclosure work rather than horns, complex geometries, or non-linear behaviour.
