When I turn on my speakers and play sound through them the bass is either full on or off as the knob is turned or wobbled I've had the woffer apart and there is no evidence of a fault so must be the turning switch itself can this be repaired or can i just buy a replacement . Cheers Kev

The problem that developed with my Creative Gigaworks and other is that occasionally it would not play at all. When the problem occurred, I could eventually get it to work again by turning it on and off several times. I opened up the powered unit (the Right speaker with the controls and found that the wires were really crammed in there, such that a white ribbon wire connector on the bottom was straining to the point of where it was slightly cracked. While playing audio through it, if I touched that wire ribbon, the sound would cut out. So I adjusted the wires slightly to relieve any tension force on that connector and it has not had the problem since. I would open up that unit and check for a similar poor or strained connection. To open the unit, carefully pull off the fabric speaker cover straight off, remove the 4 rubber inserts in the top 4 holes, and remove all 6 philips-head screws in those deeply recessed holes.
1. Push the knob on the back of the subwoofer that has the power symbol ( c- ) in. you should see a blue light turn on.
2.make sure you turn the knob on the back of the subwoofer from left to right while playing music inorder to test the level of bass you would like.
the amp probably has a x-over knob, a bass boost knob, and an eq knob.
the eq is probably an internal crossover switch that will take the
output from either high range (tweeters) or full range (6x9s) or low
pass (subs) leave it on low pass. the bass boost however, will add
distortion if turned up too high. its not noticable in the car,
actually it sounds louder in the car but if you open the trunk and
listen, you can tell its distorted bass and actually frying your
speakers. the x-over knob is used to tune the frequency at which the
amp stops pushing out bass tones. if you like rock music loud, turn it
up higher, if you like low deep rap bass, turn it lower. keeping it too
high might give you bad sound from either type though. ALSO THE GAIN OR LEVEL.IT IS NOT TO MAKE YOUR SUBS LOUDER IT WILL BLOW THEM .the gain is used to set your amp to your head unit which there is a procedure to do it.
In my case, turning the surround sound OFF is what fixed the problem. The bass contibutes most to the perception of the location of a sound. If surround is ON without surround speakers connected, the internal TV speakers can only take the place of what would be the front speakers in a surround system. So turn surround OFF and set your bass preference wherever you want it. That worked for me.
Hi, it is possible that the sub volume control is worn out. If your particular brand/model uses the rotary/wiper type (variable resistor) then replacing it should do the trick but this involves soldering which be done by an electronics technician or qualified to perform such repairs/replacement. Hope this helps. Cheers.
Check any wiring coming or going to the subwoofer. It sounds like it could be a loose connection. Is there a LFE or bass boost knob on your subwoofer? Does turning that up/down cause the crackling (if it exists). If so, you could use some tuner cleaner to clean the contacts on the potentiometer knob.
If the crackling is on the subwoofer only, it might be damaged from bottoming out. See if you can remove the baffle or grille covering the woofer and inspect for visual problems. You can also try to lighly push in and out on the subwoofer to hear if it makes any scraping sounds. If so, it is definitely damaged and the driver will have to be replaced.
