    My subwoofer is making a loud buzzing sound and it is distorting the sound so much that I can barely hear it at all. A week ago the subwoofer would buzz for 15 seconds or so and then stop, but now it does not stop at all. My subwoofer is about 2 1/2 years old and shouldn't be having these problem already. Please help me fix this!!

If you have still the problem, I got the solution from Kef USA. It is somewhat involved in taking the unit apart and replacing a resistor and capacitor. With the instructions supplied any electronic techician or TV repair man can do it in less then 1 hour. email me and I forward the instruction in PDF: [email protected] . Replace the first X with a and last X with m in my email address.

The sub has been power-zapped somehow. That unit has very touchy electronics...and mine got hit one more time after your stage and was dead completely.

Why does our subwoofer all of a sudden start to buzz when we turn on our stereo/home theatre system on?
Well if it buzzes only for a couple minutes after turn on then it could be when the woofer starts pumping it produces pressure in the cabinet which creates a bonding motion that then closes the cracks, kinda like glue. Like blowing a balloon up in a box. The balloon is the pressure, OR Yes it could be your woofer is going bad. All speakers have voice coils. Tiny wire wrapped around a thin layer of cardboard then attached to the cone. This cone could be getting loose. But when the woofer heats up after a couple minutes it probably bonds the tiny wires so then the vibration or buzzing disappears. Over time woofers can die especially if it produces a lot of distortion, In a speakers life distortion kills and it doesn't matter how much power it can handle or how much money you spent on it.
Not all sub-woofers are alike. Some can handle the really low lows, and some can not. Check your settings too. Over time the vibration of the woofer will start to undo the glue, nails, screws, and even burn through the tiny wires in the voice coil. Oh and make your china crawl across the table... Have you been watching a lot more action movies? Some of the older woofers can't handle the newer digital deep bass frequencies... You may have to reconfigure your setup.

I got a subwoofer jbl 145 wiht my system after one hour of use it make a noisy sound very loo buzzing sound and i have to power it off to stop it!
A very low buzzing sound usually indicates that the speaker is on its way out. Its the small period of time when the speaker is making sound or not.

Subwoofer suddenly making buzzing sound but is not hooked up to anything,fuses arent blown and its been in the same spot for a few years and never had a problem.happened suddenly.moved it to another spot...
hi pls make sure that there isn't any other magnetic or electromagnetic device near the speakers because due to induction ur speakers magnetic field gets distorted which makes that buzzing sound irrespective of no fault wiring may be this may help u or see that the wiring near the woofers speaker magnet is attached strongly so that it doesn't distorts any more was this helpful if yes pls vote

Hi, my sunfire Jr. sub has a distorted sound like a blown baffle. At times the sound corrects itself and plays ok, then it goes back to a distorted sound. It was not played for many hours and was handled...
I think it will be most likely a semi-conductor device that is overheating. Probably the main amp device. Subs are basically mono amplifiers.

PS8 Subwoofer started buzzing non-stop
with nothing connected and the sub turned on....Most subs buzz when the circuitry starts to fatigue. The last time I heard this ..the repair ended up being one of the two fat capacitors inside the sub. I have a means of testing this,,you may not. I am a repair shop with a bit of experience in component level board repair.

I recently connected my satellite reciever to my
Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

Jl 12w3v3 started smoking after hookup
Dang man you roasted it, take it in and get it replaced.Check the gain on the amp try it at 1/3 to 1/2 gain and dont crank up the bass boost all the way try it at like 2/3 that should clean up your sound and cut down distortion-distortion kills subs by heat.

NEED TO KNOW HOW TO PROGRAM A REMOTE PAD FOR A MAZDA 626 EX 1995 PLEASE I REPLACED THE BATTERIES AND EVER SINCE THEN THE REMOTE DONT WORK
1. Remove key from ignition.
2. Close all doors.
3. Open driver side door and leave open.
4. Insert key in ignition, Turn key to ON (as far as you can go without starting the engine) and OFF, Remove Key.
5. Repeat step 4 two more times, making sure you remove key each time.
6. Close and then open the driver’s door three times.
7. Buzz sound or chime should be heard at this point signaling that the vehicle is now in programming mode. If not,
wait 40 seconds and return to step 1.
8. All transmitters need to be programmed at this time, including the old ones. Push any button on a transmitter two
times. A buzz sound to chime should be heard at this point signaling that the vehicle has accepted the new
transmitter code. Repeat for next transmitter, up to a total of three remotes (including any old remotes).
9. After all remotes are programmed, wait 15 seconds or until you hear four chimes signaling successful
programming.

Good luck and this should work.

Amp occasionally turns itself off and back on again. Sometime stays off and has to be powered off before it will come back on.
