It s a compact, value-priced sound system. And yet the Altec Lansing VS2420 packs an incredible wallop. Delivering crisp, clean sound from custom-engineered dual, full-range 2.5 speakers. You get surprising highs, mid-range and lows from efficient little satellites that take up a minimum amount of space on your desk. Controls are right on the front of the speaker. A handy headphone jack is right nearby, too. And there's even a secondary input jack that lets you connect your MP3 or CD player while still linked to your PC.
