What is subwoofer distortion and how does it occur?
Subwoofer distortion occurs when a subwoofer is unable to accurately reproduce the low-frequency audio signals it is receiving. This can happen for a variety of reasons, including when the subwoofer is overdriven, meaning it is being asked to produce more sound than it is capable of handling. When a subwoofer is overdriven, it can cause the speaker’s diaphragm to move beyond its normal range of motion, resulting in a distorted sound.
In addition to overdriving, subwoofer distortion can also occur due to other factors such as a poorly designed or malfunctioning amplifier, a low-quality subwoofer, or incorrect settings on the subwoofer or amplifier. Regardless of the cause, subwoofer distortion can be a frustrating problem for audiophiles and music lovers, as it can significantly degrade the overall sound quality of a music system.
What does subwoofer distortion sound like?
Subwoofer distortion can manifest in a variety of ways, but it is often characterized by a “fuzzy” or “muddy” sound.
