Design boxes that hit.
Full physics simulation, not simplified formulas. Sealed, vented, and bandpass — from driver parameters to printable cut sheet.

3
enclosure types — sealed, vented, bandpass
Simulate. Optimize. Build.
01
Simulate
Pick a driver, set your enclosure — get SPL, impedance, group delay, excursion, and port velocity from a full circuit model.
02
Optimize
Latin hypercube sampling with two-pass refinement. Weight for output, sound quality, or balanced. Every candidate is build-validated.
03
Build
Cut sheets with port routing, kerf bends, corner strips, and panel dimensions. 3D preview to inspect every joint before you cut.
Physically simulated. Not approximated.
Every effect that changes what comes out of your box is modeled in the circuit — not bolted on as a warning after the fact.
| RokketBox | Typical tools | |
|---|---|---|
| Circuit simulation | ✓Full electroacoustic equivalent circuit, 500 freq points | ✗Simplified transfer functions |
| Radiation loading | ✓Bessel/Struve series on cone and port | ✗Typically omitted |
| Port turbulence | ✓Iterative nonlinear convergence | ✗Static warning or flag |
| Motor compression | ✓BL Gaussian falloff near Xmax | ✗Not modeled |
| Cabin gain | ✓3-axis standing wave model for your vehicle | ✗Flat boost or not available |
| Cabin–port coupling | ✓Port impedance modified by cabin back-pressure | ✗Port and cabin modeled independently |
| Voice coil inductance | ✓Lossy semi-inductance (Wright model), not ideal Le | ✗Ideal inductor or omitted |
| Port end corrections | ✓Flanged vs free-end on both circular and slot ports | ✗Single correction or none |
| Group delay | ✓Savitzky-Golay smoothed, plotted per config | ✗Rarely shown |
| Subsonic filter | ✓Binary-search HPF keeping excursion within Xmax | ✗Manual selection |
| Build validation | ✓Port routing rejects unbuildable designs automatically | ✗User responsibility |
| Optimizer scoring | ✓De-scores high excursion, port chuff, and unfittable ports | ✗No penalty for marginal designs |

See it before you cut it
Interactive 3D viewer with exploded view, transparent panels, and port routing visible inside the box. Inspect every joint, fold, and brace before you make a single cut.
Printable cut sheets, ready for the workshop
Every panel, port fold, brace, and corner strip — dimensioned and laid out on a single printable page. Take it straight to the table saw.
- Panel dimensions— Exact measurements for every piece, including kerf offsets
- Port routing layout— Fold lines, bend radii, and total port length shown in cross-section
- Bracing & strips— Corner strip lengths, brace positions, and driver cutout diameter
- Material summary— Panel count, total sheet area, and a cut list you can hand to a shop
