THE TOOLS IN YOUR WORKSPACE

From driver parameters
to enclosure details.

The same controls and terminology
you will find in SubForge Studio.
Feature access depends on your edition.

01 / DESIGN

Cabinet & construction

Set cabinet dimensions and wall thickness. Configure baffles, bracing, edge radii and materials. Select an edge or brace in the viewport to edit it.

Explore Design ↗

02 / ANALYSE

Response at a glance

Read SPL response, input impedance and cone excursion together. The frequency inspector adds phase, port or passive-radiator motion, and group delay.

Explore Analyse ↗

03 / BUILD · PRO

Review before you build

Open engineering checks and the conceptual cut list. Export simulation results as CSV or a printable construction report for further review.

Explore Build ↗

DRIVER & T/S PARAMETERS

Start with your driver

Filter the driver catalogue by manufacturer, select a model or enter your own T/S values. Configure voice coils, driver count and series/parallel wiring.

Driver data and wiring ↗

AMPLIFIER / DSP

Control the signal

Set source voltage up to 100 V RMS and source resistance. Pro adds high-pass and low-pass filters at 6, 12, 18 or 24 dB/oct, plus parametric EQ.

Amplifier and DSP controls ↗

GOOD TO KNOW

Let’s clear things up.

Your questions, answered.

Who is SubForge for?+

For DIY builders, audio enthusiasts, and designers exploring subwoofer enclosures through 3D geometry and acoustic simulation. A basic understanding of driver parameters helps you interpret the results.

Which enclosure types are supported?+

The simulation core supports sealed enclosures, infinite baffle, bass reflex, and passive radiators. Choose the load in Acoustic Load. Free is limited to single-driver sealed designs; other loads require Basic or Pro.

Is SubForge free?+

The app has Free, Basic and Pro editions with account sign-in and online licence verification. Free covers single-driver sealed designs and response graphs. Basic adds advanced enclosures and construction; Pro adds DSP and build/export tools. Basic costs €49 and Pro costs €99, including one year of updates. You keep your version when updates end; an optional extra update year costs €29. Compare editions and update terms. Create your account, try Free, or buy Basic or Pro through the secure account page. Download the Windows app from Downloads.

Is my design ready for manufacturing?+

This preview is a design tool. The cut list is conceptual: verify joints, tolerances, cutouts, and actual hardware before manufacturing. Simulations do not replace measurements.

Does SubForge run on macOS or mobile?+

The current Studio preview targets Windows x64. There is no Android release offered here. No macOS or iOS versions are offered on this website.
