No sound coming out of Subwoofer other speakers working fine

Hello,

Are you plugging the sub into a 3.5mm jack or USB?
Have you tried to plug the sub into the speaker jack?
The sub works on another computer?

Bad sub or bad jack?

I hope this helps!

Hiya by rattling i am assuming like something loose/fell off etc (rattling sound or distortion on the speaker itself is different, speaker could be damaged or braiding damaged that 'Might" make the speaker come in and out.) Something could have come of the PC board and may not be to serious. Probably protecting as not 100%. It may be as simple as resoldering the part but if not sure on your side i would advise seeking some help. Best of luck

Hi janros123 - I don't know if this will help - I have a subwoofer ACS48 that needs satellite speakers (they are blown). Want to buy my subwoofer or sell your satellites? I will buy your broken subwoofer, too...thanks, and good luck! Greg illdooyoo at gmail dot com

The problem is that you need the satallite speakers , they have the volume control on them which thats why you only hear the subwoofer.. yes , i tried other speakers to it and no sound either.So you will need the satellite speakers it come with.. good luck!!

THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.

cheak setting in sterio out put for sub on ect does woofer have sperk wire going in and out use them then ok

Ditto, i've got all 5 speakers without the Subwoofer. The subwoofer hasn't worked from day one, but I delayed replacing the unit for too long and don't have the warranty, I looked at all soldered connections and none of them have come un-soldered and all connectors are properly connected, can't think of anything but broken component that would cause it from here, nor can I think of a quick fix

Had the same problem when mine first arrived. Unplug and replug the power cord at the back of the woofer. Worked for me!

did you tell the receiver that you have a subwoofer connected (thru the quick setup)?
