Klipsch Flexus Core 200 + Surr 100 (set of 2) + Sub 100 (set of 2)
Specifications and features
Overview
This complete setup combines the soundbar Flexus Core 200, two subwoofers Sub 100, and two surround speakers Surr 100 to create a wireless 5.1.2-channel system. The result of a partnership between the American acoustic expertise of Klipsch and the Japanese technical precision of Onkyo, this modular package puts Dolby Atmos and wireless connectivity at the service of a detailed, powerful sound.
The Core 200 soundbar, cornerstone of the system
Measuring 1.12 meters in length and just 78 millimeters in height, the Core 200 offers a 3.1.2-channel configuration in its 8.5-kilogram chassis. Eight drivers make up its architecture: four 57 mm front-firing speakers with aluminum cones fine-tuned by the brand’s acousticians, two upward-firing 57 mm speakers aimed at the ceiling, two 102 mm woofers for built-in bass, and a 19 mm tweeter mounted in a dedicated horn for the center channel.
This central horn, a signature Klipsch technology since the Klipschorn, guides dialogue with controlled dispersion. Tense scenes in psychological dramas as well as action sequences saturated with sound effects retain their intelligibility at all volume levels. The four top drivers handle Dolby Atmos information with physical speakers rather than software virtualization, directing overhead effects toward the ceiling to create a three-dimensional sound sphere.
The 185 watts of continuous amplification power this setup, capable of projecting up to 99.8 decibels. The enclosure blends metal, textured wood, and fabric stretched across the faces, with rounded vertical edges to soften its visual integration. The two built-in 102 mm woofers already provide substantial low-end support, making the addition of external subwoofers optional for medium-sized rooms.
Two Sub 100 units to explore the lowest frequencies
Each Sub 100 is a compact 34-centimeter cube, clad in ebony black vinyl with a wood-grain finish. The 254 mm driver uses a paper-fiber cone, a historic material at Klipsch, known for its ability to move air with agility. The compliant suspension maximizes cone excursion, allowing significant travel to reproduce the deepest bass.
The sealed MDF enclosure favors speed of response over ultimate low-frequency extension. This approach enhances transient precision, which is especially noticeable in complex movie soundtracks where explosions and impacts must erupt and then vanish instantly. The frequency response extends from 26 Hz to 250 Hz with a tolerance of ±3 decibels, thus covering the spectrum from infrabass to upper bass.
The class D amplifier delivers 80 watts continuous with peaks up to 160 watts. The maximum sound pressure level reaches 103.7 decibels, in line with the capabilities of the main soundbar. Using two subwoofers in the same room provides several technical advantages: increased radiating surface, reduced load on each individual cone, and better spatial distribution of low-frequency waves to mitigate room modes specific to each listening space.
The Surr 100, discreet satellites shaping the sound field
Standing 17.1 centimeters high and 10.5 centimeters wide, the Surr 100 are among the most compact surround speakers on the market. Their single 76 mm full-range paper-cone driver covers the 235 Hz to 20 kHz range. Each unit delivers 50 watts continuous and can project up to 103.5 decibels, allowing flexible placement in the room without fear of insufficient power.
The compact format makes installation easy on shelves, furniture, or wall mounting via the integrated metric threaded insert. Unlike traditional surround systems that require cabling from the satellites to the soundbar, each Surr 100 simply plugs into a power outlet with its 2-meter right-angle power cord. This autonomy eliminates the need to route cables across the room.
Their role is less to project pinpoint directional effects than to broaden the soundstage and enrich the overall ambience. In a forest scene, the rustling of leaves, cracking branches, and birdsong spread around the listening position without ever precisely revealing the location of the speakers. This acoustic discretion is the hallmark of a successful integration.
Transport technology and control via mobile app
The Flexus system relies on Klipsch’s proprietary Transport technology, a wireless link operating on the 2.4 GHz band. This frequency ensures a stable transmission in most home environments, resilient to interference from coexisting Wi-Fi networks and cordless phones. Initial pairing of the subwoofers and surround speakers with the central soundbar is performed automatically via the supplied Flexus Transport modules.
Once synchronization is established during first use, the components reconnect automatically every time they are powered on. Transmission latency remains imperceptible, a fundamental requirement for maintaining lip-sync in on-screen dialogue. Unlike older generations of wireless systems that introduced noticeable delays, Transport technology preserves temporal coherence across all channels.
The Klipsch Connect Plus app for iOS and Android centralizes system control. Settings include a customizable equalizer, left-right balance, several sound presets (Movie, Music, Surround), a Night mode that reduces dynamic range for late listening, and a three-level Dialogue Boost function. The level of each subwoofer and each surround speaker can be adjusted independently to tailor the sound to the room’s acoustic characteristics.
The Core 200 includes an HDMI 2.1 input with eARC support for direct connection to the TV, a digital optical input, a USB-C port, and Bluetooth 5.3 with A2DP and AAC codecs. The RCA subwoofer output allows for adding a third wired subwoofer if the room layout requires it. The supplied backlit remote control provides immediate access to essential functions, complementing app control or TV remote control via the CEC protocol.
What the press says
The Klipsch Flexus Core 200 soundbar is excellent for TV shows and dialogue-rich media. Its stereo frequency response provides a good amount of bass for a standalone bar, adding punch to action-packed series. Its discrete center channel delivers naturally sounding dialogue thanks to a well-balanced midrange.

For those looking for a soundbar to enhance their TV's audio system, the Klipsch Flexus Core 200 is worth considering but shouldn't top the list. It creates a wide sound field and handles Dolby Atmos well, but ultimately, it doesn't hit the core of the sound like its rivals do. If we were to buy at this level, our money would go to the Sonos Beam for its rich and expressive audio quality.

Frequently Asked Questions
How is the wireless connection between the soundbar and the other components established?
The Sub 100 subwoofers and Surr 100 speakers communicate with the Core 200 soundbar via Klipsch Transport technology operating on the 2.4 GHz band. Each satellite component comes with a pre-paired transmission module. Installation simply involves plugging these modules into the components and connecting them to power: recognition is established automatically without further action. Subsequent sessions restore the connection as soon as the system is powered on.
Are all TVs compatible with this system?
The Core 200 supports three types of connections: HDMI eARC (recommended for Dolby Atmos), digital optical (limited to 5.1 channels without Atmos), or Bluetooth (music only, with possible latency). TVs equipped with an HDMI ARC or eARC output offer the best compatibility. Older models with only an optical output will also work, but they cannot transmit Dolby Atmos soundtracks. The CEC connection allows the TV to control the soundbar’s volume with its own remote.
What is the range of the Klipsch Transport wireless connection?
Transport technology ensures a stable link in standard residential layouts without major obstacles between components. Effective range depends on the environment: thick walls, metal cabinets, or numerous electronic devices can reduce operating distance. In a typical living room configuration where the surround speakers are three to four meters from the soundbar, no dropouts occur.
Does the system support DTS formats?
No, the Flexus range decodes only Dolby Digital, Dolby Digital Plus, and Dolby Atmos tracks. Blu-ray discs encoded in DTS-HD or DTS:X will fall back to the stereo or standard Dolby Digital track if available. This limitation stems from software licensing choices made by Klipsch and Onkyo during development. Video streaming platforms overwhelmingly favor Dolby for their content, minimizing the practical impact of this omission.
How do I perform the initial setup of the complete system?
First, place the Core 200 soundbar in front of the TV and connect it via HDMI eARC. Turn on the soundbar; it will calibrate itself automatically. Then plug each Sub 100 into a power outlet with its Flexus Transport module connected: the LED indicators will blink and then go steady, indicating successful pairing. Repeat the process with the Surr 100 speakers. Download the Klipsch Connect Plus app to adjust the level of each channel according to your listening layout. The entire process takes about fifteen minutes.
Does the system require any specific acoustic calibration?
The Klipsch Connect Plus app lets you manually adjust the level of each channel (subwoofers, surround speakers) to compensate for the quirks of your room. Unlike higher-end soundbars that integrate an automatic calibration microphone such as Dirac Live found on the Flexus Core 300, the Core 200 relies on your ears and a few empirical tweaks. Play a familiar reference scene, gradually increase the surround level until you clearly perceive their contribution, then slightly reduce it so they enrich the ambience without drawing attention to their location.
