Speaker Crossover Calculator

Design and calculate passive loudspeaker crossover networks with precision. Whether you are building custom hi-fi monitors, home theater speakers, or car audio systems, Speaker Crossover Calculator helps you compute component values, inspect schematic diagrams, and plan your builds.

SUPPORTED FILTER TYPES & TOPOLOGIES
• 2-Way Crossovers: Independent woofer and tweeter branches with parallel topology or series first-order configuration.
• 3-Way Crossovers: Dedicated woofer, band-pass midrange, and tweeter network branches.
• Single-Driver Filters: Dedicated low-pass, high-pass, or band-pass filters.
• Filter Orders: 1st order (6 dB/oct), 2nd order (12 dB/oct), 3rd order (18 dB/oct), and 4th order (24 dB/oct).

SCHEMATICS & ELECTRICAL RESPONSE
• Interactive circuit schematics showing exact capacitor and inductor positions for every driver branch.
• Ideal frequency response plots illustrating filter slopes and crossover transition points.
• Exact electrical values displayed in practical component units (mH, µH, µF, nF).

PARTS LIST & DESIGN MANAGEMENT
• Complete bills of materials organized by component reference and driver branch.
• Save multiple crossover designs to review and edit later.
• Side-by-side design comparison table to evaluate component values across different iterations.
• One-tap export to share or copy component lists for parts sourcing.

BUILT FOR AUDIO BUILDERS
• Clean, focused interface designed for speaker builders, DIY audio hobbyists, and sound technicians.
• Fast calculation engine with immediate recalculation as driver impedance and crossover frequencies change.
• No account required. All calculations and saved designs remain private on your device.
