Crank up the audio on your PC with this 2.1 speaker system and enjoy clean, crisp, consistent sound from your games, music, and more.
The Logitech X-230's high-tech subwoofer adjusts itself dynamically to deliver distortion-free bass. And the two wall-mountable satellite speakers use Logitech´s patented FDD2™ technology to eliminate the uneven sound response created by conventional dual-driver designs. The result: a clear, uniform sound field without the "hot spots" and inconsistency of other dual-driver satellites.
Frequency Directed Dual Driver (FDD2) satellite technology produces a uniform sound field for full, rich sound
Dynamic, real-time bass equalization maximizes bass response while minimizing distortion
Ported subwoofer design displaces more air for deeper bass
Headphone jack enables private listening
Master volume and subwoofer level controls placed for quick, convenient access
Satellite speaker stands rotate for easy wall-mounting
