No sound from subwoofer of logitechR20/2:1 speaker system

Depends on the type of sound system. Some require you to hook up to the subwoofer then the subwoofer to the sound system, others are just a direct line in to the sound system (in which case simply un hook the sub woofer. If it requires hook ups to the woofer, see if you can turn the volume down on the woofer directly.

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!

sure u can. but depends either your system is active or passive. active means the speakers (or sub) driven by built-in amplifier, so the dvd delivers a low signal to the speakers amp and they amplify the sound for the speakers. passive means the amplifier is built into the dvd and delivers the amplified sound signal to the speakers thru speaker cable. if you tell me model number and brand i can find out what type they are.

open your subwoofer because main system is inside in your subwoofer than clean it with a air blower ..
this happens when dust is inside the system....

Subwoofers are only speakers! You do not need drivers for speakers or woofers. You only need drivers for you sound/audio card/device. Probably you need the audio/sound software to configure the sound system for the "subwoofer and its satellite speakers.

perhaps you wired the subwoofer backwards, you got the positive and the negative mixed up on one of the speakers

It sounds like you need to define the speakers to the PC. Find the icon that controls your Sound Card and dabble with it.

You can't just do that. Your sound card needs to have a specific jack just for subwoofers. If you plug it into the speakers, the computer recognizes the subwoofer as a pair of headphones and routes all sound through it. Remember, a subwoofer is not a normal speaker. It only allows a frequency of extremely low sounds (a.k.a. BASS) and won't play anything that you would need a tweeter for.

sony suks.is it a powered sud?if not take any battery and touch the leads on the speaker if u get a sound speaker is workig.

Er so you plug the speakers into anther system and they work? Blindingly obvious but there is no fault with the speakers.
