## What is Speaker Box Lite?

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.

Upgrade to PRO for unlimited projects, offline database access and all advanced features.

Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your Account Settings.

### 5/5 — Best speaker box maker

*2026-04-14*

Allowed you to model bandpass, vented, and more. Graphs of everything. It also can generate a cut list for enclosures from sealed to complex bandpass enclosures. I have been building speakers using this app since I was in highschool. Would recommend.

### 1/5 — Прога ОТСТОЙ

*2026-01-16*

Прога отстой как и разработчик!) Безполезное приложение еще и платное. Я лучше в магазине заплачу еще и меньше.Там хоть грамотно все сделают! А тут кот в мешке и с гавн.м))

### 5/5 — Толково

*2026-01-15*

Толковая прога с кучей возможностей в про режиме, но регулярно крашится при некоторых сочетаниях параметров. Причём при перезапуске сразу же крашится снова и приходится переустанавливать и начинать прэкт с начала, эт мешает работе, поэтому 4.

### 1/5 — Do not waste your time!

*2025-11-12, version 1.35.2*

I spent 30 minutes putting all of my subwoofer parameters into this app to build a Enclosure for my sub well after all of that it says you need to rent the pro version to get the box info.  Considering the app is called “Speaker Box Lite” you would assume it would help with a speaker box. Nope.  Complete waste of time.

### 1/5 — Scammed

*2025-05-26, version 1.33.3*

Paid the subscription fee. Logged in. Then it asked me to pay for it again. Got ripped off.

### 1/5 — Useless

*2025-05-19, version 1.33.3*

You cannot even design a basic box without paying for the pro version. Waste of time downloading it.

### 1/5 — Scam.

*2025-02-02, version 1.31.7*

So I’ve had this app for years. Paid for the pro for years. But now it tells me I can only use certain parts unless I have pro. Well it’s funny that I’m paying for it and STILLL CANT USE IT. Have records for the payments and it still kicks me out. What is the problem??????????? Stop scamming and fix the dam app

### 1/5 — Все тоже

*2025-01-04*

Как осталась ошибка вы указали не все обязательные параметры так она и осталась ничего вы не исправили

### 5/5 — Completo e funcional

*2024-09-18, version 1.31.3*

Apenas elogios à funcionalidade, mas carece de opções de idioma , particularmente português(PT-BR)

### 1/5 — Ruim

*2024-07-12, version 1.30.6*

Além de quase tudo ser pago não presta
