In terms of pure sonics, the Flexus Core 300 can easily pass off without the addition of a subwoofer for all but the most demanding of movie passages or heavy metal binges. Especially with Dirac Live on, it offers a clean, musical low-end that is devoid of any boom, albeit with limited SPL below 60Hz. In fact, the overall dynamics of the Flexus Core 300 are a bit tame for what you’d expect from Klipsch, and it’s most likely due to the active nature and abundance of DSP that the small drivers are always kept in check to avoid overdriving them.Read C
This soundbar, which is long, but not exceedingly deep or tall, feels better built than any Klipsch sound bar I can recall laying my hands on. Now, I don't know how many that has been actually. I just know this feels like a really legit piece of gear, and that is almost always a good start. When you pick this thing up, you'll realize how heavy it is, and I think you'll feel the same way.Watch H
The Core 300, flagship of the range launched in 2024, represents a revolution with its 13 drivers: four front speakers, two side speakers, two elevation speakers, a central horn tweeter, and above all four integrated 10 cm woofers.

The Klipsch Flexus Core 300 is the best soundbar overall, because its built-in subwoofers, Dirac Live room correction, and expandable design offer more performance and flexibility.

The Klipsch offers powerful built-in bass, 5.1.2 audio and Dirac room correction with greater upgrade flexibility.Watch W
The Core 300 is one of the pricier soundbars on the market, but its subwoofer is at the cheaper end, particularly compared with the Sonos Sub 4. Despite its price, the Flexus is impressive. It expertly renders the long deep drones that make thrillers and horror films so intense, and the louder rumbles from explosions and thunder without ever feeling out of step with the soundbar.Read P PremiumHIFI in English PremiumHIFI in English · 1.4K subscribers · Aug 2026

However, I was so impressed with the CEDIA demo that I kept reaching out to Klipsch, trying to get a review sample.

Klipsch has made some welcome improvements since we reviewed the Flexus Core 200 this time last year. But the 300 soundbar section alone takes a significant price hike.Read W
It's going to make it a little bit tough to mount it under a TV with a soundbar mount. You have to find one that can, you know, support a lot of weight. Not to mention, if you have a heavy TV already and a heavy mount, then you're just adding another 30 lbs to the weight limit. So, it's something to consider. Uh, I think it definitely looks good on the wall if you use the included wall mounts.Watch A

But I'm going to be honest with you, the app, it works, but it's not winning any beauty contests. It gets the job done, EQ, settings, updates, all that, but yeah, it could definitely feel smoother. Still, once you're past that, you don't really think about it again. The wild card, Dirac room correction. Now, this is where things get interesting.Watch
