Immerse yourself in the game with the outstanding surround sound of Logitech's X-540 speaker system. Dual driver satellites use patented FDD2 technology to eliminate the uneven response created by conventional dual driver designs. Matrix mode creates 5.1 surround sound from 2- channel sources. The innovative center channel speaker clips onto the top of most flat-panel LCD monitors. The ported subwoofer features dynamic, real-time equalization that maximizes bass while minimizing distortion. The X-540 also features a convenient control pod with volume and subwoofer level controls, as well as a headphone jack for private listening. Satellite stands rotate for easy wall mounting.
