By understanding and addressing cabinet resonance, you can significantly reduce subwoofer rattling and enjoy a cleaner, more immersive audio experience.
Excursion Limits And Distortion: How Exceeding The Subwoofer’s Excursion Limits Can Cause Rattling.
When it comes to subwoofer performance, understanding excursion limits is crucial. Excursion refers to the maximum distance a subwoofer’s cone can move back and forth. Every subwoofer has its limitations when it comes to excursion, and exceeding these limits can lead to rattling and unwanted vibrations.
One common cause of excursion limits being exceeded is excessive bass boost or high-volume levels. When the volume is cranked up too high, the subwoofer’s cone may start to vibrate or hit against the enclosure walls, causing rattling noises. This can also occur when low-frequency signals with high levels of distortion are played through the subwoofer.
Additionally, lack of proper power handling and impedance matching can contribute to excursion limit issues. If the subwoofer is being overpowered or the amplifier’s impedance doesn’t match the subwoofer’s requirements, it can result in excessive cone movement and rattling.
To prevent these problems, it’s crucial to understand the specifications and limitations of your subwoofer. Always match the amplifier’s power output to the subwoofer’s power handling capabilities and ensure the impedance is correctly matched. Additionally, avoid excessive bass boost or playing distorted audio, as these can push the subwoofer beyond its excursion limits and result in annoying vibrations.
