Speaker Box Lite vs Hide

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.

Hide is a leatherworking calculator with cited math. Every SPI, every thread-length rule, every edge-finish recommendation names its source. Pay once at $6.99 for Hide Pro — no subscription, no ads, no scanner. The wedge Most leatherworking apps stop at thread length. Hide includes thread length in the free tier (matches the incumbent's full surface) and unlocks the rest with one $6.99 lifetime purchase: saddle-stitch SPI by leather weight × project, edge-finish recommendation by leather temper, glue selection by use case, dye + sealant by goal, brand-aware presets. Every method tells you whose method it is. Free tier • Thread-length calculator — Stohlman's precision rule and Armitage's generous heuristic, side-by-side, with the leather-thickness math shown • Leather weight oz → mm thickness conversion (1 oz ≈ 0.4 mm per Tandy convention) • 1 saved project slot • Brand picker showing the supplier names Hide Pro ($6.99 lifetime) • Saddle-stitch SPI by leather weight × project type, with awl-hole spacing in mm / inches • Edge-finish matrix — burnish with water + gum tragacanth, burnish + Tokonole wax, edge paint, or wax burnish — selected by leather temper (veg-tan smooth, veg-tan thick, chrome-tan, bridle, oil-tan) • Glue selection matrix — contact cement vs EVA white vs PVA vs hide glue — by use case + dry time + odor • Dye + sealant matrix — spirit / oil / water dye, Resolene / acrylic / wax sealant, with compatibility warnings • Brand-aware presets: Tandy Leather, Buckleguy, Maverick Leather, Wickett & Craig, Horween — typical SKU ranges + edge-finish recommendation per their leather chemistry • Unlimited project log • Citations & Sources screen with every author named Honest authority story Leatherworking has no USDA / AOCS / Knife Steel Nerds equivalent.

Sherman), Corter Leather & Cloth (Eric Heins), plus tannery technical sheets from Wickett & Craig, Horween, and Sedgwick & Co.
