Score: 85/100
Klipsch Flexus Core 200
Score: 90/100Rankings

The Flexus Core 200 is a premium 3.1.2-channel Dolby Atmos bar with dual built-in subwoofers and a horn-loaded tweeter, delivering immersive height effects and strong bass without an external sub. It excels in power and expandability but is heavy, lacks Wi-Fi and has a finicky app. Best suited for medium-to-large rooms where immersive cinema sound is a priority.

The Sonos Arc Ultra is a premium 9.1.4-channel Dolby Atmos soundbar delivering deep bass, clear dialogue, and a spacious 3-D soundstage, tightly integrated with the Sonos ecosystem. Its modern Wi-Fi 6 and Bluetooth 5.3 connectivity are strong, but the lack of HDMI inputs and DTS:X support limit flexibility.
