Expand the Flexus sound system with surround speakers. The Flexus sound system consists of two elegant soundbars, Flexus Core 100 or 200, a pair of compact surround speakers (SURR 100), and a powerful subwoofer (SUB 100). Thanks to the immersive Dolby Atmos technology, the Klipsch Flexus Surround 100 speakers create a true multi-channel surround sound setup. The Flexus SURR 100 surround speakers work exclusively with the Flexus Core 100 and 200 soundbars. They can be wall-mounted or placed horizontally for flexible positioning. No adapters, dongles, or speaker cables are required. Each Flexus surround speaker simply plugs into a power outlet and can be hung on the wall, placed on stands, in a bookshelf, or on a console behind the sofa. Klipsch Wireless Technology ensures ultimate connectivity. Quick and easy connections with a push of a button between all Flexus products (soundbar, surrounds, subwoofer) are made possible by Klipsch transmission technology. The Flexus surround speakers are powered individually, eliminating the need to hide power supplies, and provide a sleek solution for multi-channel audio. With controls, power supply, and LED lighting hidden beneath the surface, there are no distractions in a pitch-black room—just great sound and a clear aesthetic. 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.
