Design and Build
The Klipsch Core 100 is engineered with a focus on premium materials and a versatile aesthetic. According to the manufacturer, it was meticulously designed down to the last millimeter using a combination of metal, plastic, and wood for its enclosure. The compact dimensions of 28 inches wide, 3 inches high, and 5 inches deep allow it to fit discreetly under most televisions or be wall-mounted, making it suitable for various room sizes and setups.
Weighing 11 pounds, the unit has a substantial feel that suggests robust internal construction. The design philosophy emphasizes a look that can blend into any space, avoiding overly flashy elements. Owners in reviews have noted the product feels heavy and well-built, with one specifically mentioning a sharp appearance with walnut and grey fabric accents. The packaging is also highlighted by Klipsch as being eco-conscious, designed to minimize waste and maximize recyclability.
Performance and Features
Audio Performance and Core Technology
The heart of the Core 100’s performance is its collaboration with Onkyo, integrating what Klipsch describes as hundreds of years of combined audio expertise. The 2.1-channel system is built around proprietary Klipsch Transport technology and is powered by exceptional acoustics. The key audio components are two 2.25-inch ceramic drivers, which are finely tuned by Klipsch acousticians, and dual 4-inch built-in subwoofers. Klipsch claims this configuration delivers best-in-class bass, eliminating the immediate need for an external subwoofer. The system has a total power output of 150 watts.
A central feature is Dolby Atmos processing technology. This is designed to create a more immersive, multidimensional soundscape for content that supports it, such as the latest movies, TV shows, and games. It processes audio to give a sense of height and spatial placement, aiming for a cinema-like experience. The manufacturer states the sound is custom-tuned, and the product underwent over 1,000 rigorous tests to ensure performance and reliability.
Connectivity and Control
The Klipsch Core 100 offers a versatile set of connectivity options to suit different setups. It supports Bluetooth for wireless audio streaming from compatible devices like smartphones and tablets, with a listed range of 10 meters. For wired connections to a television, it includes HDMI eARC (Enhanced Audio Return Channel), which allows for high-quality audio transmission and control via a single cable, and an optical audio input. A USB port is also listed among its connectivity technologies, though its specific function (e.g., for service or media playback) is not detailed in the provided data.
Control is primarily handled through an included remote control, which requires 2 AAA batteries. Additionally, Klipsch offers app control for the Flexus system, allowing for setup adjustments and management from a smartphone. This app integration provides more versatile control over the soundbar’s settings and is part of the ecosystem management.
Expandable Ecosystem
A defining characteristic of the Flexus line is its expandability, facilitated by the patented Klipsch Transport technology. The Core 100 is marketed as the first step in building a whole-home entertainment ecosystem. Users can wirelessly add Klipsch Flexus Surround 100 speakers and one or two Flexus Sub 100 wireless subwoofers to create a more immersive multichannel setup, such as a 5.1.2 configuration. This technology is designed for lightning-quick connections between components, offering a future-proof path for those who wish to start with a soundbar and later expand to a full surround system.

Setup, Support and Ownership
Setup appears straightforward based on owner feedback, with multiple reviews citing ease of installation. The soundbar can be connected via the included optical cable or HDMI eARC. Users report that it powers on and functions immediately with these connections. The physical setup is complemented by the Klipsch app, which likely guides users through any necessary configuration or tuning for their specific room.
As noted, the system is designed for easy expansion. The Klipsch Transport technology allows for the wireless addition of surround speakers and subwoofers from the Flexus lineup. However, one owner review indicated a potential compatibility caveat: they paired a larger, non-Flexus Klipsch wireless subwoofer and found the wireless capability was not compatible, requiring additional wired connections. This suggests that for seamless wireless expansion, sticking to the dedicated Flexus accessories is recommended. Klipsch backs the Core 100 with a 2-year limited warranty from the date of purchase, providing a standard period of coverage for defects in materials and workmanship.
What Owners Say
Overall owner sentiment is very positive, reflected in the high average rating. The majority of reviews are 5-star, praising the sound quality, build, and ease of use. Common praises include “full even sound” for both TV and music, “great quality” from a trusted brand, and specific compliments on clarity, good bass, and very clear dialogue, especially with an enhanced mode engaged. Several owners highlighted the product’s weight and construction, describing it as extremely well-made and heavy, which they associated with quality.
The critical feedback is minimal but instructive. One 4-star review called it a “great entry level soundbar” but expressed a wish for the higher-end model for true surround sound and noted the aforementioned disappointment with expanding using a non-Flexus Klipsch subwoofer. This points to the Core 100’s position as a foundation rather than a complete solution for some users. The very small percentage of lower-star reviews does not provide specific, recurring criticisms in the data provided.
Pros and Cons
Pros
- Dolby Atmos processing for immersive, spatial audio.
- Powerful, custom-tuned bass from dual built-in 4-inch subwoofers.
- High-quality construction with premium materials.
- Straightforward setup with multiple connection options.
- Seamlessly expandable to a full wireless surround system.
- Clear dialogue reproduction and full sound profile.
Cons
- Base 2.1 configuration lacks true surround sound without add-ons.
- Built-in subs may not satisfy users seeking extreme, room-shaking bass.

Who Should Buy It (and Who Should Skip It)
The Klipsch Core 100 is an excellent choice for viewers and gamers who want a substantial audio upgrade from their TV’s built-in speakers and value immersive, cinematic sound from a simple, single-unit solution. It’s ideal for those who appreciate deep, integrated bass without the footprint of a separate subwoofer box. It also perfectly suits the planner who wants to start with a quality soundbar now, with a clear, wireless path to add surround speakers and a more powerful subwoofer later to build a complete Klipsch home theater.

This soundbar may not be the best fit for audiophiles or home theater enthusiasts who demand the absolute highest fidelity, discrete channel separation, and earth-shaking low-end from a large, dedicated subwoofer right from the start. Those who know they want a full 5.1 or 7.1 surround system immediately might find better value in a bundled system. Similarly, users who prefer a completely app-free experience or who have strict compatibility requirements with existing non-Flexus Klipsch wireless gear should consider this potential limitation.
Final Verdict
The Klipsch Flexus Core 100 successfully delivers on its core promise: providing a powerful, immersive, and convenient audio foundation. The integration of Onkyo technology and Dolby Atmos processing results in a soundscape that is a dramatic improvement over standard TV audio, with particularly praised clarity for dialogue and a satisfying bass presence from its built-in subwoofers. Its solid build quality and thoughtful design make it a visually unobtrusive yet sonically prominent addition to any living room or entertainment space.
Where the Core 100 truly stands out is in its forward-thinking design. It doesn’t just sell a soundbar; it offers an entry point into the Klipsch Flexus ecosystem. The Klipsch Transport technology ensures that your initial investment is protected, as you can easily and wirelessly expand your system when you’re ready for more. For anyone seeking a high-performance soundbar that can either stand alone as a major upgrade or serve as the heart of a future surround sound system, the Klipsch Core 100 is a compelling and well-executed option.

FAQs
Does the Klipsch Core 100 come with a separate subwoofer?
No, it does not include a separate subwoofer. The Core 100 is a 2.1-channel soundbar with two 4-inch subwoofers built directly into the main unit. Klipsch has tuned these to provide what they describe as best-in-class bass, eliminating the need for an external subwoofer for many users. However, the system is expandable, and you can add a dedicated Flexus Sub 100 wireless subwoofer later for even deeper bass.
Can I use this soundbar without the smartphone app?
Yes, you can use the basic functions with the included remote control. The app is required for initial setup optimization, accessing advanced sound settings, and managing the ecosystem if you add other Flexus components like surround speakers. For day-to-day volume control and power, the remote is sufficient.
What is the difference between Dolby Atmos processing and having up-firing speakers?
The Klipsch Core 100 features Dolby Atmos processing technology. This means it can decode Dolby Atmos audio signals and uses advanced audio processing to create a sense of spaciousness and height within the limitations of its speaker array. It does not have dedicated upward-firing drivers found in some higher-end soundbars or add-on modules, which physically bounce sound off the ceiling. The processing aims to simulate a multidimensional effect.
Is the Klipsch Core 100 compatible with all televisions?
The soundbar is compatible with televisions that have either an HDMI eARC port or an optical audio (Toslink) output. Most modern TVs have at least one of these connections. The HDMI eARC connection is generally preferred as it can carry higher-quality audio formats and allows for easier control between the TV and soundbar using a single remote.
