The Klipsch Flexus Core 300 with Sub 200 + Surr 200 is a put-it-together-yourself bundle available from the legendary audio brand, expanding the all-in-one Klipsch Flexus Core 300 bar. If you like to see a roll call of collaborators, this one is quite international: there are Klipsch of the United States of America, and the Flexus line is ambiguously 'powered by' Onkyo of Japan, while Sweden's Dirac handles the software tuning. This premium committee-designed soundbar bundle boasts tons of tweakability.
Our Verdict
The Klipsch Flexus Core 300 with Sub 200 + Surr 200 is excellent for mixed usage. Between its deep bass, thanks to its outboard subwoofer, extensive wired and wireless connectivity and audio format support, the kit provides a full sound for everything from movies to music. You can use the basic version of Dirac Live included for room correction, alongside plenty of EQ presets, or the custom three-band EQ to hone the already warm frequency response. It works well as an entertainment hub with HDMI In video passthrough and full-featured wireless platform support, though there's no smart assistant, so it won't replace your voice assistant.

The Klipsch Flexus Core 300 with Sub 200 + Surr 200 is amazing for TV and dialogue-heavy content. It's well-tuned, especially in the stereo mode and the center channel, with plenty of extra features like an EQ with presets, a speech boost option, room correction, channel adjustment, and dialogue modes. For high-budget TV shows, it supports virtually every common audio format, so it can take advantage of surround sound and Dolby Atmos, which are available on many streaming platforms. It features extensive wireless connectivity, so you can stream over AirPlay, for example, too. That said, its latency is fairly high, so it may need some fiddling with the Lip Sync feature in the app.

The Klipsch Flexus Core 300 with Sub 200 + Surr 200 is excellent for listening to music. It features a pleasantly wide soundstage without noticeable gaps. Thanks to the subwoofers, it reproduces your music collection with plenty of low-end rumble you can feel, though some genres might overpower the treble's details. Fortunately, it comes with a range of sound enhancement tools to customize the tuning to your space and taste, including a room correction tool powered by Dirac Live. In addition, the soundbar supports an exhaustive list of wireless streaming connections, making it easy to pair with your preferred platform.

The Klipsch Flexus Core 300 with Sub 200 + Surr 200 is great for watching movies. It supports virtually every common audio format via HDMI In and eARC, including Dolby Atmos, DTS:X, and Dolby Digital Plus, to give your films an immersive quality. An Optical port is on the menu for older devices, too. Its outboard subwoofer delivers deep bass to liven up action-packed scenes, alongside a well-tuned, albeit warm sound. In concert with the suite of sound enhancements and the Dirac room correction, it'll fit into your space. That said, it's not the loudest soundbar, particularly with Dirac Live enabled, and it costs extra to get the full version license. There's some latency as well, but you can use the Lip Sync feature to compensate.

Differences Between Sizes And Variants
The Klipsch Flexus Core 300 with Sub 200 + Surr 200 is made of discrete products that you bundle yourself, meaning that depending on which combination of products you assemble, you'll experience different results. However, the core of the various configurations available centers around the all-in-one Klipsch Flexus Core 300, available in 'Black' (like our unit) or 'Walnut Vinyl.' The satellites, Klipsch Flexus Surr 200, are solely available in 'Black' (like ours), but some regions call this 'Ebony Vinyl,' and the same applies to the Klipsch Sub 200 (a photo of our label). In the Flexus line, you may choose the Klipsch Sub 100 or Klipsch Surr 100 instead of the respective 200 models, and we expect these to have an impact on the performance.

Popular Soundbar Comparisons
The Klipsch Flexus Core 300 with Sub 200 + Surr 200 represents the brand's entrance into modular soundbar designs. While the total outlay results in a more costly option than respected flagships like the Samsung HW-Q990F, the ability to customize and build out your home theater means you can buy pieces as you need them with the Klipsch. This modularity places the Klipsch in the realm of the Sonos Ultimate Immersive Set with Arc Ultra, which you can collect, mix-and-match with other Sonos products, or purchase as a kit. But the Sonos has fewer connections and is less tweakable compared to the Klipsch. If tweakability, lots of bass, and volume headroom are key for you, check out the Nakamichi Shockwafe Wireless, so long as you've space for dual outboard subwoofers. On the other hand, the Klipsch is arguably more user-friendly without sacrificing wired connectivity, and it boasts better wireless support. As a 7.2.4 soundbar, the Klipsch also represents a leap up from the 3.1.2 satellite-free, Klipsch Flexus Core 210 (consisting of the Klipsch Flexus Core 200 and the Klipsch Sub 100).

For most people, the Samsung HW-Q990F is a better pick than the Klipsch Flexus Core 300 with Sub 200 + Surr 200, but it depends on your preferences, as they're both compelling premium soundbars. The Samsung is more user-friendly and not as expensive, with more consistent Atmos performance. Despite its smaller size, it reaches higher output volumes in stereo. That said, the Klipsch delivers more powerful, deeper bass, which you might prefer, or find a bit overwhelming for the treble range. Its stereo soundstage is a little more expansive, too. Then again, it sports one fewer HDMI port, and its latency is worse than the Samsung's (which might only be an issue for gamers and live events). Both models deliver great performance, and it may come down to the details of your personal setup to decide.
The Samsung HW-Q990D is a bit older than the Klipsch Flexus Core 300 with Sub 200 + Surr 200, so despite being a flagship, it may present better value-for-money than the Klipsch. The Samsung is smaller without sacrificing volume headroom or balanced tuning across channels. Its height performance is better than the Klipsch's, and you get a second HDMI In port for better connectivity. Still, the Klipsch supplies a more impressive low-frequency extension and a slightly wider stereo soundstage, but it's not as loud, and details can sound a bit veiled without additional EQ tweaking. Price differences aside, either soundbar might work better for your specific home theater configuration, depending on your priorities.
The JBL Bar 1300XMK2 and the Klipsch Flexus Core 300 with Sub 200 + Surr 200 are both soundbars that offer impressive performance. They each reproduce all kinds of audio accurately, with a satisfying touch of extra thump and rumble that makes movie soundtracks feel exciting. The JBL gets a bit louder, but the Klipsch has better passthrough support, including 4k @ 120Hz. On the other hand, the JBL offers lower latency across all input types.
The Klipsch Flexus Core 300 with Sub 200 + Surr 200 consists of the Klipsch Flexus Core 300 standalone bar with add-ons to transform it from a 5.1.2 bar to a 7.2.4 kit. Since these share the same base bar and app support, the main differences with the outboard subwoofer and rear speakers are (unsurprisingly) in the bass response, surround sound, and height performance. Unless you're short on space or cash, the full kit performs better with a much fuller bass response, even though the all-in-one is no slouch thanks to the integrated subwoofer, and the satellites produce a more convincing surround and Atmos experience. Since you can purchase the satellites and subwoofer separately, you have the option of buying the bar first to see if it suits you as is, though.
