Design your perfect speaker box — skip the math and jump straight to building. Speaker Box Lite calculates subwoofer and speaker enclosures for you: sealed, ported (bass-reflex), 4th & 6th order bandpass, passive radiator, and transmission line. Get optimal volume and tuning recommendations, then see your box in full 3D with auto-generated blueprints and cut sheets. BUILT-IN SPEAKER DATABASE Search 5,000+ drivers from 300+ brands — Thiele-Small parameters load with one tap. Can't find yours? Add it manually in seconds. DESIGN IN 3D Place speakers and ports, add braces and dados, choose materials — and watch your enclosure come together. Design custom waveguides for tweeters and ports — conical, elliptical, hyperbolic and radial horn profiles included. SIMULATE BEFORE YOU BUILD Frequency response, phase, group delay, cone excursion and SPL plots. Compare enclosure variants side by side and pick the one that sounds right — before you cut a single board. COMPLETE SYSTEMS Multi-way boxes with subs, mids and tweeters. Full crossover designer: low-pass and high-pass filters (Butterworth, Linkwitz-Riley and more), series and parallel notch, Zobel, RC and RL contour networks, plus L-Pad attenuation. EXPORT & BUILD Export cut sheets and blueprints for every panel. 3D-print custom ports and waveguides via STL, or export the whole enclosure and its parts as STL. Send parts to CNC in STEP format for precision cutting. YOUR PROJECTS EVERYWHERE Free account keeps projects in the cloud — start on your phone, continue on the web at speakerboxlite.com.
