Welcome to RokketBox

RokketBox is a free, browser-based tool for designing and optimizing subwoofer enclosures.

Whether you're building your first ported box or designing a 4th-order bandpass for competition, RokketBox gives you the simulation, optimization, and build tools you need — all in one place.

What can you do with RokketBox?

Simulate — Select a driver from our database (or enter parameters manually), choose an enclosure type, and see the full frequency response, impedance curve, group delay, port velocity, and excursion plots in real time.

Optimize — Let the optimizer explore thousands of configurations using Latin hypercube sampling. Choose from weight presets (SPL, SQ, Balanced, Bandwidth) and the optimizer finds the best dimensions, tuning, and port configuration for your goals.

Build — Generate precise cut sheets with all panel dimensions, port routing details, corner strip positions, and kerf bend specifications. Preview your design in 3D before cutting a single piece of MDF.

What's supported?

• Sealed enclosures
• Vented (ported) enclosures with straight, C-fold, U-fold, circular, and kerfed port routing
• 4th-order bandpass with coupled two-chamber simulation

What's next?

We're working on user accounts and saved designs, so you can come back to your projects. We're also planning tiered pricing for builders who need more than the free tier's cut sheet allowance.

Stay tuned — and happy building.
