If you listen to the home theater effect on a computer, you should have a powerful feeling, but if the bass is too high, the speaker will make a "bang bang bang" sound. This is due to the vibration of the speaker cone. The amplitude is too large and has exceeded its vibration amplitude limit, and the bottoming sound of the speaker is caused by the voice coil colliding with the magnetic pole. This phenomenon is extremely harmful to the speaker. You should stop immediately and turn down the volume and bass. set up. If you want to improve this situation, you need to replace the speaker with a higher power.
