About this app

Speaker Box Lite is a subwoofer box calculator and 3D design tool for DIY audio and car audio. Design your whole speaker system — from box calculation and tuning to multi-driver setups, crossovers, and ready-to-cut panels.

Enter Thiele-Small parameters (FS, VAS, QTS) and get the optimal box volume instantly.

Subwoofer box & bass
Pick the enclosure type for your target sound:

• Sealed (closed)
• Ported / bass-reflex (round or slot port)
• Bandpass (4th & 6th order)
• Passive radiator
• Transmission line (TL) / quarter-wave for deep, smooth bass

Subwoofer database
Search 5,000+ subwoofers and drivers from 300+ car audio brands — Thiele-Small parameters load with one tap. Add your own drivers to the shared online database.

3D design
See your box in full 3D. Place speakers and ports, choose materials, and design the box to fit your car trunk.

Tweeter waveguides
Design tweeter waveguides to shape dispersion and help integration with the midrange. Change the geometry (conical, elliptical, hyperbolic, radial) and check the concept before you build it.

Multi-way systems
Build 2-way / 3-way / multi-range systems with several drivers. Compare options, match levels, and put together a system that blends properly.

Crossover
Design and tune crossovers for a cleaner result:

• High-pass / low-pass / band-pass
• Series & parallel notch, Zobel, RC & RL networks, L-Pad
• Set crossover frequency and tonal balance

Simulate before you build
Compare designs with clear frequency response, phase, cone excursion and SPL charts — in-car and free-air. Cut the trial-and-error and reach your target sound faster.

Cut sheets & export
Get automatic cut sheets and blueprints for every panel. 3D-print ports and waveguides via STL, export the box or its parts as STL, or send parts to CNC in STEP format.

Your projects everywhere
Create a free account to save projects in the cloud and access them on any device. Start on your phone, continue on the web at speakerboxlite.com.

Note: some advanced features are available in PRO — unlimited projects, offline database access, and export.

Ratings and reviews

This isn't an app! It's an elaborate ad for an app. It allows you to view a very limited worldwide database of speaker models, then spend a lot of time entering speaker specification adjustments, and enclosure & port data, and when you want to view the box results of all your effort it says you need to subscribe monthly to get them. It won't give your actual results unless you pay. Instead, it shows an animation of its own example of a box it could make, not your results. BOOOOO! >:(

Used to be a great app, now the main feature (getting box dimensions!) is locked behind a paywall. $5.99 a month! Are you joking!? I'd pay a one time fee, even it it were more than this, but I'm not paying for a subscription. That's just greedy. You're banking on someone forgetting/not noticing they are paying for a subscription. No, I won't re-subscribe every time I want to use it. F you, I'll use something else!!!

The subs listed as out of date and inaccurate parameters. They don't let you update it for yourself, only if you submit them for review (which apparently takes forever) and the final design part aka the only part anyone cares about is locked behind a subscription pay wall. Absolutely trash app. Worse than useless. Complete waste of time.

What’s new
