3PC MUSIC & GAMING SPKRS ALL BLK Turn it on, and it roars. The VS4121blk system gets a lot of its power from a long-throw subwoofer that pushes serious bass reproduction into the room. But the down-firing midrange drivers in each speaker are what really make the difference. "Downfiring" meaning they're angled downward toward the table or whatever surface the system is on. And they use that surface for exceptional sound dispersion. It's no wonder Altec Lansing is now issuing the VS4121 in a matte black, 70th Anniversary edition. Good looks. Incredible sound. Plug it into your PC or MP3 player, and you've got the whole package.
