Non-Linear FEA Loudspeaker Spider Design & Simulation Software

FINESuspension allows acoustic engineers to design, simulate, and analyze loudspeaker spider and suspension systems—including compliance, damping, and mechanical behavior. Developed specifically for loudspeaker engineers by loudspeaker engineers, this advanced software streamlines driver development and mechanical optimization for professional acoustic engineering projects.

Advanced capabilities & engineering features:

    • Non-Linear Finite Element Calculations: Computes precise Kms(x), Cms(x), and F(x) curves for both spiders and surrounds to calculate their combined mechanical effect accurately.
    • Template-Driven Design: Build highly precise profiles by entering dimensions directly into five different geometric template configurations.
    • IEC 62458 Standards Compliance: The total linear range for the combined spider and surround system is clearly calculated and displayed according to official industry testing standards.
    • Symmetry Optimization: Automatically optimize suspension profiles to achieve perfect mechanical symmetry at your required X(max).
    • Direct CAD Support: Design specialized or custom spiders and surrounds from simple CAD files utilizing standard DXF formats.
    • Comprehensive Material Database: Includes a built-in materials database featuring typical spider and surround materials and parameters, with full flexibility to inject your own custom material profiles.
