Audio technology is really making big strides, and it's obvious here. The Altec Lansing AL-VS2421 is an incredibly compact, value-priced system that gets its powerful, full-spectrum sound from custom-engineered, dual 2.5" speakers, plus a thin yet powerful 5.25" subwoofer that fits easily under your desk. The system's size is ideal for small spaces - and you can even mount the satellites on your wall. Controls are conveniently located on the wired control unit, which includes volume and treble controls.  A handy headphone jack is also located on this unit and even an Auxiliary input jack is added so you can connect your MP3 or CD player directly to the speakers.  For extra convenience a microphone has also been built into the control unit so you can use the AL-VS2421 for internet communication
