## What is Bassport Pro?

Bassport Pro helps you design and tune car audio systems with practical calculators and tools you can use in the garage, in the install bay, or during tuning sessions.

Core tools:
- Bass reflex design (port diameter, length, Fb)
- Port tuning by box volume and port dimensions
- Quarter-wave resonator length and section range
- Speaker wiring (series / parallel / mixed) with impedance results
- Power cable sizing with minimum section and recommended AWG
- Sine generator for setup and test tones
- Gain target voltage calculator
- Box volume builder and port velocity check

Why Bassport Pro:
- Fast, installer-friendly workflows
- Clear result sheets and sharing options
- Calculation history and quick reuse
- Multi-language localization (English, Russian, Portuguese, Spanish, Japanese, Thai, Chinese)
- iPhone + iPad support

Use Bassport Pro to reduce setup errors, speed up enclosure planning, and get predictable low-frequency performance.

## Version history (last 5 releases)

### 1.1.6 — 2026-03-23

- Improved bass reflex calculations: unified speed-of-sound model with temperature, revised port end correction, and consistent formulas between Design and Tuning.
- Added advanced port parameters: selectable end conditions, port-count support, slot-port support, and better warnings for unreachable geometry.
- Updated port-velocity calculation: results now explicitly show Peak Mach based on `Xmax` and selected frequency.
- Improved quarter-wave resonator calculation: temperature support and optional open-end correction.
- Updated power cable calculator: selectable conductor material (Copper/CCA/Al), amplifier-class efficiency presets, and refined current model.
- Refined box-volume calculator: dimension units (mm/cm/in), correct conversions, and single-unknown-side solve mode.
- Improved interface: haptic feedback on toggles, hidden scroll indicators, and clearer hints/warnings on calculation screens.
- Localization fixes: removed mixed-language strings, translated new fields/results/FAQ into supported languages, and improved term consistency on bass reflex screens.

### 1.1.5 — 2026-03-19

- Added bass reflex calculation updates: selectable port shape (round or rectangular) and speaker count.
