What is a Subwoofer Crossover?

A subwoofer crossover is a type of electronic filter circuit that routes audio signals based on their frequencies. It is used in audio applications to send low-frequency signals (typically below 200 Hz) to the subwoofer, while higher frequency signals are sent to other speakers. This ensures that the subwoofer only produces the deep bass sounds it is designed for, improving overall sound quality and preventing damage to the speakers.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ F_c = \frac{1}{2 \pi \sqrt{0.001 \cdot 0.000001}} = \frac{1}{2 \pi \sqrt{0.000000001}} = \frac{1}{2 \pi \cdot 0.00003162} \approx 5032.92 \text{ Hz} \]

The Crossover Frequency is approximately 5032.92 Hz.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ F_c = \frac{1}{2 \pi \sqrt{0.005 \cdot 0.00001}} = \frac{1}{2 \pi \sqrt{0.00000005}} = \frac{1}{2 \pi \cdot 0.0002236} \approx 713.43 \text{ Hz} \]

The Crossover Frequency is approximately 713.43 Hz.
