CHAPTER
Klipsch’s long history of speaker design is reflected in the Flexus Core 300. Dialog is always intelligible without flat music and effects, and the overall balance is warm and easy to listen to.
Introduction
Klipsch has been around since 1946, and they are not new to soundbars. The company introduced the first Reference-branded sound bar, the R-10B, in 2014, and later released high-end Cinema systems, including the Cinema 1200 flagship.
The Flexus series is a collaboration between Klipsch and Onkyo under the Premium Audio Company umbrella, and that company family changed in 2025 when Gentex acquired VOXX International (which owned Premium Audio Company). The Flexus Core 100 and Core 200 came first, and the Flexus Core 300 followed as a model to step up the line.
The Flexus Sub 200 subwoofer and Flexus Surr 200 surrounds connect wirelessly and are sold separately.
At the heart of the system is a dense driver framework. Klipsch describes the Core 300 as a 13-driver design built around four front-firing 2.25-inch drivers, a 0.75-inch horn-loaded tweeter, two 2.25-inch up-firing elevation drivers for Dolby Atmos, two 2.25-inch side-firing drivers to extend the 4-inch high-end presentation, to boost bass output without requiring a subwoofer.
In terms of price and purpose, the Flexus Core 300 system stacks up against flagship soundbar packages like Samsung’s HW-Q990F. Samsung relies on automatic processing and room optimization features like SpaceFit Sound Pro and Adaptive Sound, while the headliner of the Flexus Core 300 is Dirac Live room optimization. Klipsch is positioning it as the first soundbar with built-in Dirac Live, and the goal is straightforward: measure the room and apply adjustments to optimize response and improve coherence.
Klipsch keeps the concept simple: solid hardware, a few key modes, and enough control to make the system worthwhile without turning it into a science project—unless you decide to go deep with Dirac.
Large front LED display (disappearing)
Tightening the bar causes a large “HELLO” behind the grille, and that display is where the bar shows the settings as you adjust. When you stop communicating, it fades away.
Three levels to upgrade the box
The Core 300 offers several steps to improve the conversation. Even at low volume, the horn-loaded tweeter helps cut through voices. The highest setting is there for challenging mixes and very low-level dialogue.
The Klipsch Connect Plus app
The app includes day-to-day setup and control, including changing inputs, volume, EQ, listening modes, and firmware updates. This is also where you use Dirac Live.
Channel cut (quick fix)
If the subwoofer is too hot or the surrounds feel too shy, the system allows you to reduce the levels in simple steps. It’s the kind of control you use with original content, especially for all the incompatible mixes.
EQ presets and basic tone shapingYou get precise Bass/Mid/Treble adjustments and presets that can change the emphasis depending on what you’re listening to.
Movie and music modes
Movie mode prioritizes impact and range, while Music mode is aimed at stereo playback and precise balance.
Dirac Live (Limited included; upgrade available)
Dirac Live is included in limited form, with resolution up to 500 Hz; Broadband resolution is available as a paid upgrade. The workflow involves measuring your room with the included measuring microphone and saving presets for different seating positions or room layouts.
Set up and Remote
The QR code on the box points you to the Klipsch Connect Plus app. The soundbar is large (54 inches wide) and isn’t something you’ll have to juggle while plugging in a cable, but the back panel is accessible once it’s in place.
Wireless expansion of the system uses Klipsch Transport and a dedicated USB transmitter dongle. The dongle plugs into the recessed USB-A port on the back of the soundbar, and is also equipped with Sub 200 and Surr 200 add-ons. With the dongle installed and the speakers powered up, the app immediately recognized the add-ons and the system was ready to go.
Once everything was connected, I moved on to Dirac Live. The program supports saving Dirac presets, which is useful if you have more than one listening environment or often change the room setup.
Dirac is also where the friction is. In my case, the measurement process was prone to errors until I slowed down and followed the instructions carefully in a quiet room. I’ve also found that the app behaves more reliably when my phone and soundbar stay on the same local network/SSID throughout the setup.
The included remote control is small and functional, and it’s easy to make the changes you really care about—source, mode, chat enhancement, night mode, and trim level—without digging through menus. I ended up using the remote for most of the day-to-day changes and reserved the app for deep tuning and Dirac.
Working
From the first show, the clarity of the dialogue was outstanding. Even with the dialogue enhancer set to a medium level, voices remain audible without making the results sound compressed or thin. I’ve heard many soundbars “enhance” the conversation by removing the mix; Flexus method is very controlled.
For movies, built-in bar woofers carry more weight than you’d expect, but the Sub 200 is what adds the practical foundation. It delivered a low-frequency rumble without turning into a single-note throb. F1 (the 2025 racing film with Brad Pitt) had the kind of engine texture and pit-lane ambience that benefits from real low-end support, and the Sub 200 provided that scale while keeping the vocals from being buried.
Saving Private Ryan remains a reliable stress test because it requires both restraint and chaos. Quiet details came through clearly, and the most brutal sequences kept their intensity without folding into the hash.
One scene I often use to explore the environment is a drum sequence House of Flying Daggers. Played through the Surround 200 speakers, the system does a satisfactory job of positioning the songs being played and the movement ricocheting around the room. The result was very focused, even if it didn’t match the finer separation and fine detail I get from the AV receiver and separate speakers, where you can easily track the differences in tone and texture of the instrument.
Atmos music is also on the table. With Apple Music’s Dolby Atmos content, the Flexus system streams instruments cleanly and maintains a cohesive tonal balance. Compared to a big, aggressive cinema soundbar package like Samsung’s HW-Q990F, the Klipsch’s presentation is always warm and slow. That won’t be to everyone’s taste, but it can be easy to live with for all the long sessions and stuff.
The conclusion
The Flexus Core 300 system feels like Klipsch has implemented the most important of a speaker in the soundbar category: clarity, tonal balance, and the ability to tune the system without burying it in gimmicks. The bar is physically large, and the Dirac setup can test your patience, but once dialed in, the system delivers strong conversational clarity and a warm, natural presentation.
If your main frustration is always cranking up the volume to understand vocals—and you’re looking for a soundbar system that doesn’t rely on high-end to create “detail”—the Flexus Core 300 is easy to shortlist.
