How much bass to blow a sub woofer?

Blowing a subwoofer typically occurs when it is subjected to excessive power and low frequencies that exceed its handling capacity. Bass frequencies below 30 Hz can be particularly damaging if played at high volumes. Generally, it's essential to ensure that the amplifier's power rating matches or is below the subwoofer's RMS rating and to avoid pushing the volume to the point of distortion, which can cause damage. Properly tuning the system and using a high-pass filter can help protect the subwoofer from being blown.
