Question about Cambridge Soundworks BassCube 12 Speaker

Repetitive buzzing noise

Recently, my Basscube 12 subwoofer started making a repetitive buzzing noise. I would compare it to the sound you hear during the emergency broadcast system tests on the radio. It makes this sound when connected to the audio receiver and when disconnected from the audio receiver. What is causing this and how can it be fixed? Darren McNamara Bellingham, MA

Re: Repetitive buzzing noise

Some componet in the Amp circuit is breaking down. The longer you let this go, the more of a chance that you will have a major short and blow out several parts,m as thats what happens with amps. Get it service asap and dont use it.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise

I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

Loud humming noise

this may be result of blown capacitor - have it analyzed by applying strong magnet over the inside speaker , if humming persists, then its not blown capacitor -- the capacitor stores energy, and if that energy is lossed an out in the airwaves, thats the humming effect

Why is the subwoofer making a buzzing sound? Is there a solution?

I have had the same problem with my Sony sub. It sounds like it is picking up electrical noise and would not go into standby when the reciever was off. I rerouted my wires and changed to a much higher quality wire. I was using a very low quality stranded copper with thin insulation to start with.

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.

Bass Cube 12 makes loud buzzing noise when turned on !

Hi Ok thanks. I cannot be 100 % sure about this without seeing it but it sounds alot like there is a power supply issue, either bridge rec or caps. Caps are very often very obvious. If you get into it and have a look at what is normally the 2 or 4 biggest capacitors at the start/power supply of the board and see if they are ok visibily. If they are bulged, (often they actually explode and leave paper residue) then those are what need to be replaced. Have a look and see.

If its the bridge rec, it could be 4 diodes, fairly large next to each other or a square component with 4 legs out. Need a meter to test, but i would start at caps first
All the best

Home theatre sub

Sounds like a ground loop issue. Try plugging your sub, and the rest of your entertainment equipment into the same outlet with an extension strip (4 plug adaptor). If there is too much stuff to plug into one strip, experiment with combinations and hopefully you will find which piece of gear is the culprit.
