Enter the resistance and capacitance into the calculator to determine the crossover frequency. This calculator can also evaluate any of the variables given the others are known.

## Crossover Frequency Formula

The following formula is used to calculate the crossover frequency.

f_c = 1 / (2 * π * R * C)

Variables:

- f_c is the crossover frequency (Hz) R is the resistance (Ohms) C is the capacitance (Farads) π is a constant, approximately equal to 3.14159

To calculate the crossover frequency, multiply the resistance by the capacitance, then multiply the result by 2 and π. Take the reciprocal of the result to get the crossover frequency.

## What is a Crossover Frequency?

A crossover frequency, in audio systems, refers to a specific frequency point in the audio spectrum where the responsibility of producing sounds shifts from one speaker component to another. It is a particular frequency that separates the range of frequencies sent to different speakers or drivers in a multi-driver speaker system. For instance, in a two-way speaker system, lower frequencies are directed to the woofer and higher frequencies to the tweeter, with the crossover frequency being the point of transition.

## How to Calculate Crossover Frequency?

The following steps outline how to calculate the Crossover Frequency.

- First, determine the resistance (R) in Ohms.
- Next, determine the capacitance (C) in Farads.
- Next, gather the formula from above = f_c = 1 / (2 * π * R * C).
- Finally, calculate the Crossover Frequency.
- After inserting the variables and calculating the result, check your answer with the calculator above.
