The Klipsch Flexus Core 300 is a high-end 5.1.2-channel Dolby Atmos soundbar designed to serve as a solid foundation for modern home theater, gaming, and music streaming. The system combines Klipsch’s legendary acoustic signature with Onkyo’s Japanese engineering precision to deliver powerful, immersive, and balanced sound without the need for an external subwoofer.
The soundbar features a sophisticated configuration of front, side, and upward-firing drivers that create realistic spatial sound with clearly positioned effects around and above the listener. The built-in high-efficiency subwoofers deliver rich, deep bass that is impressive for an all-in-one system.
The Flexus Core 300 is the world’s first soundbar with built-in Dirac Live room correction, which analyzes the room’s acoustics and automatically optimizes the sound based on its size, shape, and furnishings. This ensures consistent and precise sound, regardless of the environment.
The model supports Dolby Atmos and DTS:X decoding, as well as a wide range of network streaming services via Wi-Fi and Bluetooth. Control and customization are easily handled through the Klipsch Connect Plus app, which allows adjustment of EQ, dialogue, night mode, and other settings.
