Description
The Boston Acoustics BA4800 is an analog 5-piece, 4-channel surround speaker system ideal for
computer gaming or any enhanced audio application at the desktop. The system includes 4
powered micro-satellites and a large, amplified, ported subwoofer for deep bass response. The
BA4800 performs best with PC sound cards offering 4-speaker output (e.g., 2 stereo outputs, front
and rear), but also sounds impressive as a 3-piece music system when connected to any headphone jack or line-level output (portable CD player, MiniDisc play er, MP3 player, etc.). With added
features like MagnaGuard
connections and speaker-mounted controls, you not only get the renowned Boston Acoustics
sound but uncommon flexibility. For more information on Boston Acoustics or our line of home
