1. What is Crossover Frequency?

The crossover frequency is the point at which a speaker transitions from one driver to another (e.g., from woofer to tweeter). It's determined by the inductance (L) and capacitance (C) values in the crossover network.

2. How Does the Calculator Work?

The calculator uses the crossover frequency formula:

Where:

• \( f \) — Crossover frequency (Hz)
• \( L \) — Inductance (Henry)
• \( C \) — Capacitance (Farad)
• \( \pi \) — Mathematical constant (~3.14159)

Explanation: The formula calculates the frequency at which the reactance of the inductor equals the reactance of the capacitor.

3. Importance of Crossover Frequency

Details: Proper crossover frequency selection ensures smooth transition between drivers, prevents frequency gaps, and protects drivers from operating outside their optimal range.

4. Using the Calculator

Tips: Enter inductance in Henrys and capacitance in Farads. Both values must be positive numbers. The calculator will compute the crossover frequency in Hertz.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical crossover frequency range?
A: For 2-way systems: 2-5 kHz, for 3-way systems: 300-500 Hz (low-mid) and 3-5 kHz (mid-high).

Q2: How do I choose L and C values?
A: Start with standard values for your desired frequency, then adjust based on driver specifications and listening tests.

Q3: What about speaker impedance?
A: This formula assumes 8Ω speakers. For different impedances, adjust values proportionally.

Q4: Can I use this for active crossovers?
A: The formula is for passive crossovers. Active crossovers use different electronic filters.

Q5: How precise do components need to be?
A: Within 5% tolerance is usually acceptable, but high-end systems may require 1% tolerance components.
