Learn how to repair or replace a home theater subwoofer and how to identify if your subwoofer needs to be replaced or repaired. From the subwoofer, check all cables and connection points that go to the amplifiers, receivers, or speakers. Check that the cables are properly connected and plugged in at the correct points. Check the power outlets, power cord, and fuse.
Most subwoofers have a standby LED that lights up to indicate active power. If it is not turned on, make sure that the subwoofer is properly plugged into a wall outlet, surge protector, or power strip. If the pins of a plug slide halfway, it is often enough to prevent the flow of energy from gently bending them so that the cable stays connected after you release it. Make sure all associated switches (i.e.
those on walls, power strips, etc.) If the subwoofer still won't turn on, try plugging it into a different outlet that you know is working properly. Verify that the cables are plugged in properly, then plug the stereo system back in and turn down the volume and equalizer. Turn on the stereo and slowly turn up the volume and bass equalizer to see if you found the problem. Play music with a lot of bass to check that the subwoofer is working.
Subwoofers give home theaters incredible sound. There's nothing like adding one or two subwoofers to enhance your home theater experience, but what happens when a subwoofer starts to malfunction? Was it ruined forever? Is it possible that it will be fixed? In a home music or home theater audio system, the subwoofer is usually one of the most important speakers in the room. When you experience difficulties with the home theater system, checking the settings of the home theater receiver can have a big impact.
