Bass Match filters the library, applies your constraints, then simulates compatible drivers. Inputs (your requirements and the filtered driver library) feed Bass Match, which simulates compatible drivers; the selected design is refined in Box Design.

Constraint-first enclosure engineering

From physical limits to predicted sound.

Define your requirements once. Let Bass Match explore the driver library, then compare compatible candidates and refine your enclosure.

  1. 01

    Set your constraints.

    Define your available internal volume, target bass cutoff (F3), and acoustic output goals. Rather than picking a random driver and forcing a box around it, start from your physical and acoustic limits.

  2. 02

    Simulate the library.

    Bass Match evaluates electroacoustic alignments across the catalog against your targets, filtering out combinations that cannot meet your goals.

  3. 03

    Explore what fits.

    Review compatible candidates side by side. Inspect simulated frequency response, cone excursion, and port air velocity, then transition seamlessly into Box Design to refine the final enclosure.
