Contact the seller and the shipper and have it replaced. You wont be happy unless you do. You will always wonder about sound quality.

SOURCE: My HKTS 7 Sub woofer makes no noise,the led burns

Subwoofer is center speaker from A+B speaker signals. first check your wire to the receiver. Otherwise you need electronics service on the amplifier inside the speaker.

The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

My sub woofer making noise like machine gun w out connect toamp


Disconnect the sub-woofer and see if the noise stops, if so the amplifier is OSCILLATING and so produces the noise.This can be related to fault with the pre-amp or audio processing section. Try and heat up the circuit using a hair dryer and if the fault clears then there are faulty electronic capacitors. If leak is seen then the pcb must be washed after the capacitor is replaced which can solve the issue.

My sub make a strange noise. It doesen't work anymore.Tks.


Strange noises can come from your amplifier or the sub itself. The most likely cause of the strange noise is the speaker just before it dies! If you have been using the sub-woofer at high volume levels then you probably have damaged it. Try testing the sub-woofer using a multimeter(on ohms setting) it should give you a reading from 8 to 4 ohms. Sometimes they may give readings as low as 1 ohm. When testing the speaker/sub you should hear a soft scratchy, thumping or clicking sound. This indicates that the speaker may still be working. If you don't have a multimeter try a 1.5 volt battery (say a AA), DONT USE HIGHER VOLTAGE BATTERIES they may damage the speaker! You will hear a clicking, scratching etc sound from the speaker which may indicate that it is still OK. If the speaker seems OK the problem may be in the amplifier, which I suggest you bring to a professional repairer. When buying speakers and amplifiers make sure the power handling of the speaker is equal to or greater than the amplifier output power. This should stop speakers from getting damaged. Make sure the speaker and amplifier specifications are rated in the same manner ie RMS PMPO Peak. A 100 Watt PMPO speaker will not survive the output of a 100Watt RMS amplifier!

nothing is wrong with the woofer the connect is broken at the strain relief and the cable needs to be replaced.
You can replace the connector if you know the pinouts. You will need the connector and the schematic.
you may be able to find the pin outs configuration here.

As for the connector this may take a search online.

I have an infinity sw12 that is for some reason making a high pitched noise and some cracking noises as well. It does seem to work otherwise. I get the same noise when the cable to the stereo is unplugged....


It could be an internal "cold solder joint" however, if your lucky, it may just be dust buildup on the control pods and switches. Radio Shack sells "Tuner Wash" which will clean potentiometers (volume controls) and other electrical contact points. It's an inexpensive "try". Pull the volume and crossover knobs and lightly spray down with the wash. Let it set 10-15 seconds then move the control pod back and forth. Turn it back on and see if it's better. Hope this helps

Sub woofer making a screaching loud noise when powered on


The pop from other electrical items makes me think it's a ground problem but I am do not have a clue as to what type of setup you are running over there. Did you try a surge protector?Is it 110volts with a seperate ground wire?
Have you tried running a UPS?
