A popping noise from the subwoofer indicates a power mismatch in the circuit. The popping noise occurs as the amplifier tries to produce more voltage than it can to meet the demands of the subwoofer. This ends up clipping the sound on every cycle.Know More
A power mismatch is not the only issue that causes a popping noise from the subwoofer. The noise may also be due to loose connections in the circuit.
To fix the error, check that the power outage from the amplifier matches the subwoofer's RMS. The amplifier producing much less power than it should could be clipping the subwoofer, but also check if it’s producing more power than the subwoofer can handle. More RMS power from the amplifier gradually heats up the voice coil and may burn it out. A solution to this is getting a condenser that’s used to steady the power and transmit it out in stable currents.
A loose connection may also exist in the wire connections to the amplifier, voice coil or in the subwoofer itself. Carefully check all these wires and ensure that none of them are loose or melted away. Wires connecting the speaker cones and voice coils should also be checked and tightened.Learn more about Audio Equipment
To build a subwoofer box for a car, cut the pieces of fiberboard, cut out a hole, fasten everything together and install the subwoofer. Be sure to measure both the space in the car as well as the subwoofer to ensure the fiberboard pieces are the correct size.Full Answer >
In order to repair a broken subwoofer cone, one must remove the woofer, construct a patch for the damage and then apply the patch with glue. Colored construction paper, adhesive, scissors, a screwdriver and minimal to no electronic skill are required. Repairing the cone is a simple process, but it often leads to compromised sound from the speaker.Full Answer >
To build a 12-inch subwoofer box you need three-quarter-inch medium-density fiberboard, 2-inch drywall screws and either half-inch or three-quarter-inch panhead sheet metal screws. Other materials and tools that are required include carpenter's glue, a jigsaw saw, an electric drill, silicon caulk, non-hardening rope caulk and a speaker terminal cup. Most importantly, a subwoofer of the appropriate size is also required.Full Answer >
Active noise-canceling headphones both play sound and block ambient noise. The headphones combine a noise-blocking structure with a system that erases lower-frequency sound waves by generating a sound wave identical to the incoming sound, but flipped 180 degrees out of phase. The system may reduce noise by 20 decibels.Full Answer >
