all 3 speaker cables are approx 6 ft long. The left and right spkrs can be extended because they plug-in. The sub-woofer is hard wired to the control pod, so it cannot be extended. Hope this helps you!
Wes, my best estimate is ~6", however, you must realize that I have a computer desk also and this estimate is made with the Logitech Z313 hooked up. Good luck! I would call Amazon customer service and get an exact measurement.
Not sure how long the cables are. They run behind my desk with the sub woofer-amp sitting on the floor and the speakers on my desk. The controller is also sitting on my desk. But in answer to your question, yes, they should be long enough since I do the same thing. I also run everything from a docking station which my laptop hooks into.
