# SubForge Studio 1.17.0 for Windows x64

Released 7 October 2026.

- Free and Basic support up to two drivers, with full driver and voice-coil wiring.
- Free includes sealed and bass-reflex designs, left/right/center standard front slotports, up to two round ports on Front/Right/Left/Top, and frame/cutout/flange dimensions. Save, Save as and Open work in every edition.
- Basic adds own T/S and amplifier inputs, up to three Aeroports with fixed flare, transverse window braces, 45° corner supports, double baffles, finishes and isolation feet.
- Pro retains up to eight drivers/round ports/Aeroports, adjustable flare, advanced slots/bracing, passive radiators, radii, DSP, automatic optimisation and build exports.
- Driver appearances are named Basic 1, Basic 2, Basic 3 and Pro 1. Basic 1–3 are available in Free, Basic and Pro; Pro 1 requires Pro. The unfinished Cast Rib / Covered model is removed from new selections; existing project geometry is preserved.
- The Port / PR velocity graph requires Pro. Free and Basic show a blurred Upgrade to Pro panel.
- Startup uses a longer animated opacity/blur reveal. The portrait login card has background blur and a shadow; logo transparency, alignment and typography are refreshed.
- Startup and New consistently produce a slotport design. Clicking paid cabinet edges in Free/Basic does not trigger upgrade prompts.
- Rounded inner cabinet faces retain slot-wall contact surfaces. Partition-side mouth radii stop at 20 cm; cabinet-wall radii at 1 cm. Degenerate triangles after fillet subdivision are filtered.
- Saved higher-edition designs can be viewed and copied without removing their paid settings.
