Klipsch Flexus Core 100: review
If you’re short on space, but still want to experience the wonders of Dolby Atmos, then the Klipsch Flexus Core 100 could be the soundbar for you. This 2.1-channel model aims to supply “immersive, spatial sound” in a single, compact bar, using virtualized Atmos.
Let’s start with a bit of a reality check. The Klipsch Flexus Core 100 has some key limitations that hold it back from delivering the expansive, three-dimensional sound that larger models offer. It uses a fairly basic 2.1 channel configuration, with four main drivers – two front-firing 2.25-inch speakers, and two built-in four-inch subwoofers.
Unlike most of the best soundbars for Dolby Atmos, the Flexus Core 100 doesn’t have up-firing drivers, which are required for ‘true’ Atmos. There’s also no center channel on offer, and as a fairly narrow bar, this thing’s not going to plate up the width you’d expect from a full-length model.
With all of that said, the Klipsch Flexus Core 100 is a pretty good-sounding model. When watching a 4K UHD Blu-ray of Top Gun: Maverick, I was impressed by accurate dialogue in the opening scene – which sounded well-defined, and maintained the echoey effect you’d expect in a wide open space.
On top of that, Maverick showcased the low-end talents of the Flexus Core 100. The rumble of jet engines was more impactful than a lot of bars in this size category – and other parts of the frequency range didn’t sound obscured as Tom Cruise’s character prepared for take off.
I will say, though, that when the jet flew up and overhead, the verticality of the move was very limited. And more generally, this soundbar struggles to conjure up a sense of height – it's understandable with its technical limitations, but it’s going to be an issue for those wanting great Dolby Atmos in a small package.
In spite of its unremarkable height effects, the Flexus Core 100 still provides a decent amount of width for such a narrow model. In The Mask, the soundbar commendably replicated the cartoonish spin of the titular character across the screen. As he smashed through a glass window, the combination of a low-end thump with a high-pitched shattering also came through with clarity and impact, capturing the surprising nature of the move brilliantly.
One small issue I picked up on was during a scene where two B-rate mobsters are playing air hockey in the backdrop. Here, the left and right channel separation seemed overzealous and choppy – likely a result of there being no center channel, as this isn't something I experienced on a 5.1 bar like the Marshall Heston 60.
As well as movies, I tried listening to some music over Bluetooth using Tidal. And like a lot of small soundbars, the Flexus Core 100 isn’t particularly talented in this department.
In Black Eye by Allie X, I was satisfied with the depth of the bass, although it wasn’t particularly agile. Meanwhile, vocals were clear enough, but not separated all too much from other sounds in the mid-range. Percussion wasn’t the most precise either, and it lacked a sense of space. Overall, I got a relatively clean listen, but one that lacked nuance or detail.
With Atmos music, it was a similar story. Dream of Arrakis by Hans Zimmer offers solid low-end punch, but the attack of percussion was fairly blunt, and vocal elements weren’t all too clear in the mix. The expansiveness of this master was also pared back quite a bit compared to what I’ve heard on more premium compact bars, like the Sonos Beam Gen 2.
Something else I realized when playing tunes, was that the soundbar didn’t automatically switch to Music mode – something I’ve become relatively accustomed to from most modern soundbars. You have to select the appropriate mode with the included remote or the Klipsch Connect Plus app.
Still, the two modes are decently differentiated, and if you want to make additional changes, you can make use of an equalizer in the companion app. And EQ options aren’t bad at all – you can manually adjust bass, mids, or treble, or switch between presets, including: Flat, Vocal, Bass, Treble, and Rock.
More generally, I was a big fan of the Klipsch Connect Plus app. It’s brilliantly responsive, well laid-out, and pretty feature-rich. On the main screen, you can change source, activate a genuinely great multi-level voice enhancement setting, activate night mode, and more. An additional settings menu also opens up channel level adjustment, surround and subwoofer pairing, and display brightness adaption.
The only thing I was really missing on the app was some kind of room calibration tool to optimize the Flexus Core 100 to my listening space – something you’ll find on soundbars like Sonos Beam 2nd Gen and Marshall Heston 120.
I touched on the Flexus Core 100’s display a moment ago, and I have to give Klipsch some kudos here – it looks absolutely fantastic. Rather than relying on a basic lighting system, there’s a large display with full letters and numbers to let you know which mode you’re using, source you’re connected to, and volume level you’re at. This is incredibly clear, and makes for a much smoother user-experience.
On top of a neat display and seamless in-app experience, setting the Flexus Core 100 up really couldn’t have been easier. You’ve just got to connect it to a power source, and hook it up to your TV over HDMI eARC or digital optical – easy as pie. You can also build your system out at your own pace by connecting a compatible wireless sub, or a wired one via the soundbar’s ‘sub out’ port. You can also purchase Flexus Surround speakers for a more three-dimensional listening experience.
In terms of functionality, the only major miss in my view is the omission of Wi-Fi streaming. Personally, this is an absolute must for me. I love being able to use Spotify or Tidal Connect to enjoy my music in higher quality than Bluetooth streaming allows. Some may also lament the lack of DTS support, which is less common than Dolby Atmos for streaming, but is often used on Blu-rays.
We’ve spoken a lot about the technology involved so far, but how does the Flexus Core 100 fare in the looks department? In my opinion, this soundbar is a little on the average side. The large logo on the right side isn’t the most attractive, and the fabric speaker grille doesn’t quite give off a premium impression. Still, the model is well-made, and I’ve already raved about its excellent display.
One thing I’ve not mentioned yet is the Flexus Core 100’s price-tag. And this is pretty competitive, all things considered. It comes in at $349 / £299 / AU$645, which is less than a 2.0 channel rival like the Denon Home Sound Bar 550 and considerably less than compact Atmos titans like the Sonos Beam Gen 2 and Bose Smart Soundbar.
In the end, then, the Klipsch Flexus Core 100 is a solid soundbar overall. It won’t deliver the most amazing Dolby Atmos, it’s not the best-looking model I’ve seen, and I’m also still sad about the omission of Wi-Fi streaming.
But its great bass levels, clear dialogue, impressive companion app support, and ease of use are all highly commendable. If you’ve got the cash, I’d suggest going with either Sonos or Marshall’s compact soundbars, but if you’re on a tighter budget, this model is well-worth considering.

Buy it if...
You’re looking for some low-end power
One of the best things about the Flexus Core 100 is its impressive bass performance. Explosions and low-end heavy scores will sound so much better than they would with plain TV audio, and your viewing experiences will improve substantially.
You’re short on space
If you’ve not got a ton of space or your TV unit is on the smaller side, the Flexus Core 100 is a very nice pick indeed. It's far narrower than a model like the Sonos Arc Ultra, making it ideal for anyone who needs something smaller.
Don't buy it if...
You want awesome Dolby Atmos performance
Although the Flexus Core 100 creates a decent sense of width, its height effects aren’t convincing at all. If you want the best Atmos possible from a small soundbar, the Marshall Heston 60 – which I’ve discussed below – is your best bet.
You need Wi-Fi streaming
The lack of Wi-Fi streaming on the Flexus Core 100 is a real shame, and is something that’s pretty easy to come across on competitors. You can still stream music via Bluetooth, but the quality isn’t going to be as good.

Marshall Heston 60
There aren’t many small Dolby Atmos soundbars that can outclass the Marshall Heston 60. It provides surprisingly expansive sound with surprisingly good Atmos for such a compact model. It’s also incredibly attractive with a mouth-watering amp-inspired design, and the inclusion of Wi-Fi streaming as well as DTS:X support is much appreciated. It’s very expensive, and its bug-prone companion app needs some work, but overall, it’s an awesome option. Read our full Marshall Heston 60 review.
Sonos Beam Gen 2
As I discussed in my Sonos Beam Gen 2 vs Marshall Heston 60 showdown, the former is still the compact Atmos bar to beat. Its exceptional dialogue clarity, powerful bass, and now-modest price just give it that edge. As a 5.0 channel bar, the Beam Gen 2 sounds more expansive than the Flexus Core 100, although it does skip on Bluetooth connectivity and a sub out port. It does deliver Wi-Fi streaming, though, and its modern design is among my favorites. Read our full Sonos Beam Gen 2 review.
How I tested the Klipsch Flexus Core 100
- Tested with movies and music across multiple hours
- Used in our TV testing space at Future Labs
- Mainly played 4K Blu-rays for movies and streamed via Tidal for music
When testing the Klipsch Flexus Core 100, I had the soundbar connected up to the phenomenal LG G5 OLED TV via its HDMI eARC port.
I spent the majority of my time with the soundbar watching 4K UHD Blu-rays – predominantly viewing them via the Panasonic DP-UB820. However, I also watched some shows on Netflix, and streamed music through Tidal using the Dolby Atmos and stereo formats.
On top of this, I made sure to exhaust all of the Flexus Core 100’s features, and cycled through all of the settings in the Klipsch Connect Plus app, including the various sound modes and EQ calibrations.
More generally, I’m an experienced tech reviewer with a particular focus on audio-visual gear, and have tested a wide range of soundbars. During almost two years at TechRadar, I’ve covered everything from budget models like the Sony HT-SF150 through to premium Dolby Atmos soundbar systems, such as the JBL Bar 1300MK2.
