Expand your Flexus sound system with the wireless Sub 100, the state-of-the-art subwoofer. The Flexus sound system consists of two elegant soundbars (Flexus Core 100 and 200), a pair of compact surround speakers (SURR 100), and a powerful subwoofer (SUB 100). Big bass, small footprint. The Flexus 10" subwoofer packs a lot of power per square centimeter thanks to Klipsch's careful engineering. The Flexus Sub 100 subwoofer works exclusively with the Flexus Core 100 and 200 soundbars, delivering powerful bass to your home theater system. Better together: two subs are better than one. With the "À la carte" system, you have the option to expand your Flexus soundbar with one or two subwoofers for more bass. Using two identical Flexus 10" subwoofers reduces distortion and consumes less power, especially in large rooms. The connection can be made via the Flexus Transport 2.4 GHz Wireless Dongle as well as with a cable. Powered by Onkyo. The Klipsch Flexus system has been carefully tested by engineers from sister company Onkyo and has undergone more than 1,000 rigorous tests to ensure fantastic audio performance and excellent connectivity options.
