Linkwitz-riley Crossover Calculator

Don't want to do the math? That’s why the calculator exists.

If you are a high-fidelity audio enthusiast or a professional speaker builder, you have likely encountered the . Widely considered the gold standard for multi-way speaker systems, this filter type ensures that your woofers and tweeters work in perfect harmony.

These values must be matched within 1% tolerance for the phase coherence to hold, highlighting the calculator’s role in precision design. Linkwitz-Riley Crossover Calculator

A is a specific type of filter used to divide an audio signal into different frequency ranges. Named after its creators, Siegfried Linkwitz and Russ Riley, it was designed specifically to fix the phase and amplitude issues found in older filter designs like the Butterworth. Key Characteristics:

Using a Linkwitz-Riley crossover calculator is the most efficient way to determine the exact component values—capacitors, inductors, or resistors—needed to achieve a seamless hand-off between drivers. What is a Linkwitz-Riley Crossover? Don't want to do the math

Using a removes the guesswork. It transforms a chaotic mess of inductors and capacitors into a mathematically precise, phase-coherent network. Whether you are using a passive 24dB design with reversed tweeter polarity or programming an active DSP, do the calculation first.

A is a specialized tool (often web-based or part of simulation software like VituixCAD or WinISD) that automates the design process. It converts your desired crossover frequency and driver impedance into the specific values of capacitors (measured in Farads) and inductors (measured in Henries) required for a passive crossover.

Use a Zobel Network or Conjugate Impedance Compensator .

In the early days of audio, engineers had to calculate component values using slide rules and complex formulas involving imaginary numbers ($j\omega$) and complex impedance. Today, we use software.
