This is a set of Klipsch multimedia speakers I have used on my compute for about 1 1/2 years. They are great speakers still in great condition. The four satellites have a 3 1/2 inch driver and the horn tweater, and the sub has two 6 1/2" drivers. It is the best system I've ever heard for computers, hands down. I am selling becuase I am moving to a new appt. and wil not have a dedicated computer room anymore. Am asking $175 for them right now, but will consider all offers. Here is a picture of them. I also have a set of wall mounts so you can mount the rears, or fronts to a wall. Email me here if you have any questions.
