Car Audio Box & Tuning Pro

Subwoofer enclosure calculator

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

From driver specs to a preliminary cut plan: compare sealed or ported boxes, inspect the 3D design, and precheck trunk space before cutting MDF. Turn subwoofer specifications and trunk measurements into a clearer enclosure plan. PLAN THE ENCLOSURE • Choose a driver from the on-device catalog or enter its Thiele-Small parameters. • Compare sealed and ported options with dimensions and small-signal response estimates. • Review usable internal volume, panel dimensions, material thickness, driver cutout, displacements, bracing, and port details. CHECK THE BUILD • Generate a preliminary cut plan and PDF for workshop review. • Inspect the enclosure in 3D with the driver opening and, when applicable, its port. • Measure trunk space manually or with camera assistance, then run a visual geometry precheck. REVIEW THE SYSTEM • Observe relative audio-response trends with the built-in RTA. • Keep core design, catalog, calculations, projects, PDF, 3D, RTA, and camera workflows on-device. • Use the app without an account, ads, analytics, or a telemetry backend. A store connection is used for purchases and restores. Built for car audio installers and shops, enclosure builders, and DIY users who know their driver model. A one-time purchase unlocks the Pro tools, with no subscription. IMPORTANT Results are small-signal design aids, not laboratory certification, large-signal proof, or a fabrication guarantee. Confirm the current manufacturer datasheet, usable internal volume, displacements, material thickness, joints, kerf, mounting clearances, trunk opening, obstacles, and installation path before cutting. The catalog may not include every driver model or parameter. The camera and trunk-space precheck does not model every curve, hinge, obstruction, insertion path, or fabrication tolerance. The phone microphone RTA displays relative dBFS and is not a calibrated SPL meter.
