My subwoofers will only play at extremely low volume

There are a number of reasons which are explained in the link. The most likely is a faulty volume control, but it could also be high voltage and the protection circuit.

go get a noise reduction box radio shack selld them for 20 bucks

The subs are making that sound when the bottom out + when they reach full excursion be careful if it keeps happening eventually your subs will fail because you will end up damaging the subs voice coil.

decrease the bass

I assume you are using XP. Try these steps.
1. Open 'Sound and Audio devices' in Control Panel.
2. Select 'Advanced...' button near bottom.

3. Select 5.1 system

4. Start playing a sound.
5. Set the volume control of the subwoofer to the middle position.
6. Open volume control and adjust Master volume to a comfortable level (i.e. until there is no hum).

Also make sure you haven't muted any sound device except microphone. I think your problem is you have set it to the maximum level. So decrease it.
7. Mute the sound and check.
Good luck! Let us know the result.

maybe the problem is on the files you play but not your device.

Sure you should when they are talking about low noise they are talking about filters to keep electrical noise out. Is there a seperate volume control on your sub woofer i know mine does. To be able to adjust how much bass you want.

It will power off if the frequency range of the signal being sent to it is set too low, or the amplitude of the signal is too low as well.

Try increasing the subwoofer crossover frequency and/or increase the gain from the LFE/SUB of the receiver/preamp you have it connected to. Also make sure that in the setup menus of ALL of your components have an LFE channel enabled such as by selecting the output of source material of your DVD player for example, to output 5.1. Otherwise, it will not send a signal for the subwoofer to play, nor will it play the signal if the crossover frequency is set too low.

Example; the setting on your DVD player setup menu is set to two channel: result with only one exception, subwoofer will not play

Example; subwoofer/LFE level on receiver/preamp set to -10dB and/or subwoofer volume too low. Result: subwoofer will not play.

Example; subwoofer crossover point set at 35Hz. Source material playing sound at 30Hz and lower. Result: subwoofer will not play.

Hi,

Offhand, could either be the subwoofer speaker itself or the electronics (amp and/or crossover). One way to determine is by physcially checking the sub speaker. When playing with bass on, pls try restricting speaker movement by pressing on it and see if the noise is reduced. Another is to temporarily replace the speaker. You can try speakers meant for the car, home entertainment or book shelf, just dont set the volume too high.

If the speakers are ruled out, then it would be the electronics inside. For this, you would need familiairty with electronic components and circuittry, a DVM and a soldering iron. Access to an oscilloscope and an audio signal generator would be nice but not a necessity. The idea is to inject a constant audio signal and determine where the noise (if electronic) is coming from. In most instances, it would be a leaky electrolytic capacitor either in the input stage or feedback loop. At other times, it would be also a capacitor in the band pass filter.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

hello, check and see if cabinet has loose screws or if back panel is tight,bass can vibrate screw loose.good luck! also look for anything caught in the woofer causing the noise.
