Why Do Tweeters Blow When Amplifiers Distort?


If you’re a music enthusiast, you understand how important it is to have high-quality audio. Tweeters are an essential component of a speaker system that helps produce high-frequency sounds. However, when amplifiers distort, tweeters can blow, which can be a frustrating and expensive experience. In this article, we’ll explore the science behind why tweeters blow when amplifiers distort and what you can do to prevent it.

Why Do Tweeters Blow When Amplifiers Distort?

Tweeters are designed to handle a specific frequency range, and they are often made of delicate materials that can be easily damaged. When an amplifier distorts, it produces a waveform that doesn’t resemble the original signal. The waveform becomes a square wave with sharp edges that contain high-frequency harmonics. These harmonics are outside the tweeter’s frequency range, and the tweeter tries to produce them. As a result, the tweeter may overheat and eventually blow.

How Amplifier Distortion Occurs?

Amplifier distortion can occur due to several reasons, including:

  1. Overdriving the amplifier: When you push the amplifier beyond its limits, it will start to distort.
  2. Using the wrong speaker impedance: When you connect a speaker that has a lower impedance than the amplifier’s output impedance, it will cause the amplifier to work harder and potentially distort.
  3. Poor quality audio input: If you use a low-quality audio input, the amplifier will have to work harder to amplify the signal, leading to distortion.

Preventing Tweeter Blowouts

Preventing tweeter blowouts is essential to maintaining the quality of your audio system. Here are some tips to prevent tweeter blowouts:

  1. Use the right amplifier: Match the amplifier’s power output to the speakers’ power rating to prevent overdriving and distortion.
  2. Check speaker impedance: Make sure the speaker’s impedance matches the amplifier’s output impedance.
  3. Use high-quality audio inputs: High-quality audio inputs require less amplification, reducing the risk of distortion.
  4. Use a crossover network: A crossover network separates the audio signal into different frequency bands, ensuring that each speaker only receives the frequencies it can handle.


Q. Can tweeters blow out due to high volume?

A. Yes, tweeters can blow out due to high volume, especially if the amplifier is overdriven.

Q. Can tweeters be repaired if they blow out?

A. It’s possible to repair tweeters, but it’s often more cost-effective to replace them.

Q. Can using a subwoofer prevent tweeter blowouts?

A. Using a subwoofer can prevent tweeter blowouts as it relieves the tweeter of the low-frequency workload.


Understanding why tweeters blow when amplifiers distort can help you prevent it from happening. By following the tips mentioned above, you can keep your tweeters safe and ensure that your audio system produces high-quality sound. So, next time you’re setting up your audio system, make sure you keep these tips in mind to avoid tweeter blowouts.
