OverviewThe Klipsch Flexus Core 300 is the flagship of the Flexus lineup and a genuine industry milestone. It is the first soundbar in the world to feature built-in Dirac Live room correction, a professional-grade technology that measures your specific room's acoustics and automatically corrects for sonic reflections and anomalies. Inside its 54-inch chassis, a massive 13-driver array delivers a true 5.1.2-channel physical Atmos experience, utilizing dedicated side-firing and upward-firing speakers to create a multidimensional soundstage that moves beyond the limitations of virtual processing.Simcoe Audio Video InsightMost soundbars are designed for a "perfect" room that doesn't exist. The Core 300's use of Dirac Live is a game-changer because it allows the bar to adapt to your space—correcting for windows, furniture, and awkward corners that usually muddy the sound. Developed in a tight partnership with Onkyo, this flagship combines legendary American horn-loaded dynamics with Japanese precision engineering, making it the most reliable and acoustically advanced soundbar we have ever offered.Best for the Klipsch Flexus Core 300: use the Klipsch Connect Plus app to run the Dirac Live calibration immediately upon setup. This doesn't just "tweak" the EQ; it aligns the timing and phase of all 13 drivers, resulting in a level of transparency and bass "tightness" that independent reviewers have noted outperforms rival flagships costing significantly more.More DetailsWhy It Wins Dirac Live Correction: The world's first soundbar to include pro-level room optimization that makes your actual room sound like a tuned studio. Physical Atmos Height: Features dedicated upward and side-firing drivers for overhead effects that are physically directed, not virtually simulated. Best-in-Class Bass: Quad 4-inch built-in subwoofers deliver impactful low-end response down to 43Hz, providing plenty of weight for daily viewing without an external box. What Makes It DifferentWhile many soundbars stop at Bluetooth, the Core 300 is a fully-featured network streamer, supporting Wi-Fi, AirPlay 2, Google Cast, and Tidal Connect for lossless music playback. It also addresses the needs of modern gamers with HDMI 2.1 eARC that supports 8K and 4K/120Hz passthrough, ensuring your PS5 or Xbox Series X performs at its peak. The construction is equally premium, featuring real wood-grain finishes in Ebony or Walnut—a rare touch in a category dominated by plastic.Technical Highlights 13-Driver Array: Includes four 2.25” front drivers, a .75” horn-loaded tweeter, and dual elevation and side-firing drivers. HDMI 2.1 Connectivity: High-bandwidth passthrough for 8K video and ultra-low latency gaming. DTS:X Decoding: Onboard support for every major high-resolution audio format. Control System Ready: Compatible with Control4 and RTI for seamless integration into a managed smart home. Buyers GuideWho This Is For The No-Compromise Buyer: Home theatre enthusiasts who want the best possible performance from a single bar without running speaker wire. The Tech-Forward Gamer: Those who need HDMI 2.1 passthrough for the latest consoles alongside high-fidelity Atmos audio. The Music Lover: Listeners who want a soundbar that doubles as a high-end Wi-Fi streamer with support for AirPlay and Tidal. Ideal Use Case Large Media Rooms: Best scaled for 65-inch and larger displays in spaces where acoustic reflections are a concern. Living Room Cinema: Provides a true 5.1.2 experience in rooms where a traditional multi-speaker setup isn't aesthetically possible. Whole-Home Audio: Acts as a high-res endpoint for your multi-room music ecosystem via Google Cast or AirPlay 2. What To Pair It With Expansion: Add Flexus Surr 200 wireless speakers (featuring their own up-firing drivers) to expand to a physical 7.1.4 system. Subwoofer: For cinematic, floor-shaking impact in large rooms, pair with the 12-inch Flexus Sub 200. Gaming Consoles: Connect your PS5 or Xbox directly to the HDMI 2.1 input for the best video and audio performance. Alternative OptionsThe Core 300 is a flagship intended for medium to large rooms. If you are outfitting a smaller bedroom or apartment, the Flexus Core 100 or Core 200 offer a similar sonic character in a more compact form factor. While the built-in subs are impressive, listeners who want "earthquake" level bass for action movies should prioritize adding a dedicated Flexus Sub 200. For those building a completely separate, discrete component system, our Klipsch Reference Premiere towers remain the ultimate high-performance choice.
