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.

Verdict
The clearest difference is rating: Speaker Box Lite at 4.1 against Airplus's 3.0. Speaker Box Lite also leads on update cadence (every 11 days vs every 5 months) and ratings volume (339 vs 2). Airplus's advantage is review sentiment (100% vs 62%) and in-app purchases (none vs 3). On price and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Speaker Box Lite sells 3 in-app purchases, starting at $4.49 per 7 days. Airplus asks for nothing beyond the download.
Speaker Box Lite holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: Speaker Box Lite has 339 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 62% of Speaker Box Lite's written reviews are positive against 100% of Airplus's, so the app with the better star average is not the one people write more warmly about.
Speaker Box Lite ships an update every 11 days, Airplus every 5 months. Both last shipped on October 24, 2026.
