The Sevens, the active speaker set with versatile applications. Whether it's a turntable, a TV, a computer, or a smartphone, The Nines provide the solution. The Nines are equipped with a built-in phono preamp, Bluetooth 5, HDMI-ARC, optical digital, analog RCA, and USB inputs. With the HDMI-ARC audio return channel, the volume is controlled via the TV remote. For stereo audio lovers, The Nines are a brilliant solution for music and TV as a stereo soundbar. For added bass, the sub pre-out connection allows for an external subwoofer. Tuned components by Klipsch engineers deliver noticeably powerful bass and room-filling sound, whether the volume is low, high, or somewhere in between. Since the human ear perceives frequencies differently at varying volumes, there are bass settings via the equalizer, either through the remote control or even more precisely in the Klipsch Connect app. Klipsch Heritage Wireless The Sevens, probably the most versatile speakers available. Available in matte black or walnut wood veneer.
