Klipsch The Nines II Powered Bookshelf Loudspeakers

Powered 2-way speakers with Dolby Atmos, DTS:X, Dirac, 1" titanium LTS tweeters, 8" Jet Cerametallic woofers, HDMI eARC, Wi-Fi streaming, Bluetooth, phono input, XLR input, and subwoofer output

Klipsch The Nines II are powered bookshelf loudspeakers designed to serve as a compact music, TV, and streaming system without requiring a separate amplifier. The pair combines Klipsch horn-loaded driver technology with an electronics platform developed in collaboration with Onkyo, supporting advanced audio processing, source switching, and system control in a self-contained speaker package.

Each speaker uses a 1" titanium LTS vented tweeter with Tractrix horn and an 8" Jet Cerametallic woofer in a bass-reflex cabinet with a rear-firing port. A one-piece BMC baffle is used to reduce unwanted resonance, with a curved radius intended to improve off-axis response and widen the soundstage.

Connectivity includes HDMI ARC/eARC with CEC, HDMI input, Bluetooth, RCA phono, RCA analog, XLR, USB-C audio, USB-A, optical digital, coaxial digital, Ethernet, Wi-Fi, calibration mic input, and a subwoofer output. The Nines II also support Dolby Atmos playback with Virtual Height Channels, DTS:X decoding, DTS Virtual:X, Dirac room correction with a standard license, 24-bit/96 kHz hi-res audio, and built-in streaming through services and platforms including Google Cast, Apple AirPlay 2, Spotify Connect, Tidal Connect, Qobuz Connect, and more.
