1. What is a 2-Way Crossover?

A 2-way crossover is an electronic filter that splits an audio signal into two separate frequency bands - low frequencies for the woofer and high frequencies for the tweeter. The crossover frequency is the point where these two bands meet.

2. How Does the Calculator Work?

The calculator uses the geometric mean formula:

Where:

• \( f_c \) — Crossover frequency (Hz)
• \( f_{low} \) — Lower frequency limit (Hz)
• \( f_{high} \) — Upper frequency limit (Hz)

Explanation: The geometric mean provides the optimal crossover point between two drivers' frequency ranges.

3. Importance of Crossover Frequency

Details: Choosing the right crossover frequency ensures smooth transition between drivers, prevents frequency gaps, and protects tweeters from low-frequency damage.

4. Using the Calculator

Tips: Enter the lower frequency limit of your tweeter and upper frequency limit of your woofer. Typical values range from 1,500 Hz to 3,500 Hz for many speaker systems.

5. Frequently Asked Questions (FAQ)

Q1: Why use geometric mean for crossover frequency?
A: The geometric mean provides equal ratio between the frequencies, creating a balanced transition point.

Q2: What are typical crossover frequencies?
A: Common ranges are 2,000-3,500 Hz for bookshelf speakers, lower for larger woofers (1,500-2,500 Hz).

Q3: How does driver size affect crossover frequency?
A: Larger woofers typically need lower crossover points as they struggle with high frequencies.

Q4: Can I use this for 3-way systems?
A: No, this is specifically for 2-way systems. 3-way systems require two crossover points.

Q5: Should I consider driver sensitivity?
A: Yes, while this calculates the frequency point, you may need to adjust levels to match driver sensitivities.
