I don't know to connect Logitech speaker to my computer.

first open the net over the speaker...top bottom corner there is a hole then in this hole put a strength stick pressure heavy by side..then it will show u crack by this crack u have to open it!!remind there is no screw in s-100 logitech speaker!!Thanx!

Um, didn't get all the jacks meaning that you don't have the yellow, green, and black cables that run from your speakers to your computer, or the jacks on the speakers themselves? You can go to Logitech's website and find the cable I'm sure, about how much it will cost, can't exactly say but possibly not cheap.. other solution is to go to walmart, kmart, radio shack, anywhere they sell electronics, and get yourself three audio cables with 1/8 in jacks on both ends... then just match colors and connect!

Those speakers are meant to just plug into a sound card or onboard sound device or any sound device that has headphone jacks e.g. iPod. They don't provide feedback to the PC, so there is absolutely no need for drivers, which is why you don't see them in device manager. Think of them as a glorified pair of headphones.

The Logitech is a little tricky. You need to carefully pry off the white bezel around the speakers and then pry away the grills. Under the grill you will find four screws holding the two speakers, and four screws set deep in holes.

Undo these eight screws and the front will come off.

Try to disconnect the input connector of your speaker and touch the input jack of the unit if you hear a hazing sound it means your speakers are working properly but if you don't hear any sound your speakers are bad. Open the speaker unit and check the amplifier section of your unit. If you don't see any burned electronic component inside. Check the wiring of your unit.
To check if the audio of your computer is working. Plug in the input a headset if you hear a sound while you playing a music in your computer it means the audio of your computer is working good.

check your green cable. did you mute sound? icon next to clock, lower right corner

I don't know what the actual connections are, but no, you can't just connect them all to an RCA plug.

Windows 7 requires different drivers for your logitech speakers. You can download the updated drivers from logitech.com
THANKS LET ME KNOW HOW ELSE I MAY HELP YOU

From my oppinion, Logitech is best for quality and clear sound,and creative too (well most of them), promax i don`t know.

Make sure you you have turned on both of the power buttons the one on the remote should be pushed down and there is also one on the back of the subwoofer just above the power cord connection. Hope that helps if not just let me know
