Klipsch The Nines II Hi-Fi Bookshelf speaker Ebony

Klipsch The Nines II Powered Speakers — Horn-Loaded Hi-Fi Without the Receiver

The Klipsch The Nines II Ebony powered bookshelf speakers pack eight decades of American audio engineering into a pair of self-contained stereo cabinets. Each enclosure houses an 8-inch Jet Cerametallic woofer paired with a 1-inch titanium LTS vented tweeter set inside a Tractrix horn — the same horn-loaded geometry that has defined the brand since Paul W. Klipsch founded the company. Built-in amplification and Onkyo-designed AVR electronics mean there is no separate receiver to buy, no rack of boxes to hide, and no tangle of interconnects behind the TV stand. Plug in a source, power on, and the system is ready for music, movies, and gaming.

What Sets The Nines II Apart in the Powered-Speaker Category

Dolby Atmos and DTS:X decoding with virtual height channels turn a two-speaker setup into an immersive surround experience, while Dirac Live room correction (Standard license included) uses the bundled calibration microphone to measure and fix acoustic anomalies in real time. The new one-piece BMC baffle is denser and more rigid than the previous generation, stopping unwanted resonance and widening the soundstage for cleaner off-axis response. Studio-style XLR balanced inputs, a built-in MM phono stage, and HDMI 2.1 pass-through with 8K, VRR, and ALLM support make this pair equally at home in a living room or a project studio.

Horn-Loaded Drivers — Why They Matter for Room-Filling Sound

The driver complement is the heart of any speaker, and Klipsch has built its reputation on horn-loaded efficiency. The 1-inch titanium LTS vented tweeter delivers articulate highs without harshness, while the 8-inch Jet Cerametallic woofer produces tight, controlled low end down to 31 Hz. Tractrix horn geometry focuses high frequencies toward the listening position, which is why these speakers sound so lively and direct even at low volumes.

• High-Frequency Driver: 1" (25 mm) titanium LTS vented tweeter with Tractrix horn
• Low-Frequency Driver: 8" Jet Cerametallic woofer — extended bass without a sub
• Maximum Output: 107 dB at 1 m (stereo pair) — concert-level headroom for large rooms

HDMI 2.1, Wi-Fi, and Built-In Streaming — One Cable, Every Source

Modern living rooms juggle TVs, turntables, phones, and computers. The primary speaker holds the entire electronics package and accepts them all through a flexible rear-panel array. HDMI eARC carries uncompressed Dolby Atmos from a television, while a second HDMI 2.1 input passes through 4K/120, VRR, ALLM, and HDR signals for next-gen gaming. Built-in Wi-Fi and Bluetooth 5.4 cover wireless streaming, and a 10/100 Ethernet port keeps network playback rock-solid for high-resolution files.

• Wireless: Wi-Fi 2.4/5 GHz 802.11ac (2×2 MIMO), Bluetooth 5.4, Ethernet
• Streaming Platforms: Google Cast, Apple AirPlay 2, Spotify Connect, Tidal Connect, Qobuz Connect, Roon Ready
• Wired Inputs: HDMI eARC, HDMI 2.1, XLR balanced, RCA phono, RCA analog, USB-C, optical, coaxial

Cabinet Construction and Physical Specs — Built to Anchor a Room

A speaker this size needs a cabinet that does not color the sound. The enclosure is finished in genuine wood veneer (Ebony on this model) with a rear-firing bass-reflex port for deeper low-end extension. The redesigned top-panel metal volume wheel and source button feel built to last, and the included backlit remote makes late-night listening easy. Power comes from an internal 100–240 V supply, so the system works in any region with the appropriate cord.

• Dimensions (H × W × D): 460 × 244 × 375 mm
• Weight: Primary speaker 14.9 kg, secondary speaker 14.4 kg
• Enclosure: MDF with genuine wood veneer, bass-reflex via rear-firing port
• Subwoofer Output: RCA line-level, crossover tuned around 65 Hz

Who Should Consider The Nines II — Audiophiles, Home-Theater Fans, and Vinyl Lovers

The Nines II are the right choice for listeners who want true hi-fi performance without the complexity of a traditional separates system. Audiophiles who appreciate horn-loaded dynamics will hear the lively, room-filling character that has defined Klipsch for eight decades, while home-theater fans get Dolby Atmos and DTS:X with virtual height channels from just two cabinets. Vinyl enthusiasts can plug a moving-magnet turntable straight into the built-in phono stage, and gamers benefit from HDMI 2.1 pass-through with VRR and ALLM for tear-free, low-latency play. The system is best suited to medium-to-large rooms where the 8-inch woofers and 107 dB maximum output can really stretch their legs.

Klipsch — 80 Years of American Speaker Engineering

Founded by Paul W. Klipsch in 1946, the company has spent eight decades refining horn-loaded speaker design in the United States. The Nines II carry that heritage forward through a collaboration with Onkyo, whose AVR electronics expertise brings modern connectivity and decoding to a classic acoustic philosophy. The Nines II won the TWICE VIP Award and was named Best of CES 2026 by eCoustics, joining The Fives II and The Sevens II in Klipsch's next-generation powered-speaker family.
