Question about Sunfire True Sub Signature Subwoofer

1 Answer

Has light but no sound

My Sunfire Signature Subwoofer stopped working recently. The main light turn on when powered and the equalizer light turns on when a signal is received. However, no sound is produced. I tried the same for another source, using both XLR and RCA inputs. Still, no sound is produced.

    I just replaced the fused with a new one. The problem was not fixed.

The first thing to always check first is the fuse. This will probably involve some disassembly but it is alwayst the cheapest fix and a constant issue.

My subwoofer output is not working properly. I have a sunfire signature that worked all the time. Now the power on the Sunfire will not come. Research says no signal from receiver. I swithed the...

You can prove the sub pre-output works by running an RCA cable from it to the input of a tape deck, TV or any other device that accepts Line In and will either display it or play it. Test it on VERY LOW volume at the receiving device.

Different sub pre-out cable?

Humming sound in subwoofer after it's been playing for a while

It sounds like you are describing an earth loop problem. I won't go into detail in this post, but try an isolation test first. disconnect everything from the reciever except the sub and try connecting say a BATTERY powered mp3 player or cd player to minimise connections to the electrical mains earth. you could also isolate things by taking your sub to a friend's house and trying it on their system.
If it is an earth loop use a process of elimination to find out which two pieces of equipment causes the earth loop. then apply filtering.
you can buy earth loop isolation transformers for about AU$26 and I've used one on my sub myself. Theyhave RCA (phono)plugs on each end and they connect inline with the signal cable to the sub amp.

as for the thumping sound it might be the speaker protection circuitry cutting off the amp to protect the subwoofer speaker from damaged. This might be triggered if the earth loop sound is causing the sub amp to overload and clip.

Failing this there might be a dried out overheated electro capacitor in the amp circuit causing the hum. Hav a chat to your local electronics person, who should be able to spot it!
Hope this puts you on the right track
Happy Hunting!

Rattling sound with any significant base output

You either ripped your voice coil, or you have something jumping around inside (Screw, nail, etc.). You can tell of a blown speaker by pressing straight in, and if you hear a rubbing noise, then your speaker has disconnected from your voice coil. Mickey mouse jobs include Krazy Glue, but It's touch and go
