TCL Design Bang Olufsen A65K vs Klipsch Flexus SUB 200 12"
Quick Verdict
This is not a direct head-to-head because one product is a complete 3.1.2 Dolby Atmos soundbar with a wireless sub, while the other is a standalone 12-inch wireless subwoofer for Klipsch Flexus sound bars only. Choose the TCL A65K if you need an all-in-one eARC soundbar with height drivers, center channel, Bang & Olufsen tuning, and calibration. Choose the Klipsch Flexus SUB 200 12" only if you already own a Flexus CORE 100, 200, or 300 sound bar and want to add dedicated low end. For most buyers without a Flexus sound bar, the TCL is the only logical choice. Verify dimensions before purchase for either product.

Sound Quality
The TCL A65K is a complete soundbar with 3.1.2 channels, dedicated left, right, center, and dual up-firing height drivers, and a total rated power of up to 460 watts. Its listing highlights Bang & Olufsen tuning and AI Sonic Auto Calibration. The dedicated center channel should improve dialogue clarity over a basic 2.1 bar. The Klipsch Flexus SUB 200 12" is not a full soundbar; it is a single 12-inch subwoofer driver with 200 watts of power. Therefore, comparing overall sound quality is uneven because one product reproduces the full range and the other handles only low frequencies.
Both products earned a sound quality score of 25 out of 30 in their listings, but that score measures different things. The TCL score reflects a full system with height channels, while the Klipsch score reflects the performance of a subwoofer alone. The Klipsch listing does not publish a frequency response or distortion spec, so its low end character cannot be verified from the supplied facts. The TCL listing also omits driver sizes, so the actual acoustic capability of its subwoofer and main drivers is unknown beyond channel count and power.
For someone buying a primary TV speaker, the TCL offers a complete acoustic design with upward-firing drivers for height effects. The Klipsch subwoofer adds low frequency output to an existing Klipsch Flexus sound bar, but it cannot reproduce dialogue, midrange, or surround effects by itself. A buyer should not compare them as equal products. The Klipsch is a bass add-on, while the TCL is a full soundbar solution with a bundled wireless subwoofer.
Surround, Atmos and Audio Formats
The TCL A65K explicitly supports Dolby Atmos and DTS:X, and its 3.1.2 channel layout includes two up-firing height drivers. This means the soundbar is designed to decode and play object-based surround formats without rear speakers. The listing does not state whether it supports other codecs like Dolby TrueHD or DTS-HD Master Audio, only that Atmos and DTS:X are supported. The Klipsch Flexus SUB 200 12" does not list any Dolby Atmos or DTS support because it is not a processor or soundbar. Its listing has no audio format support section, which is expected for a powered subwoofer.
The TCL's up-firing drivers suggest it can create a virtual height layer using ceiling reflections, though no testing or specifics are provided. The listing does not state whether the TCL supports virtual surround or rear speaker expansion. The Klipsch subwoofer has no role in decoding surround formats; it only receives a low frequency signal from a compatible Flexus sound bar. The proprietary wireless link likely passes the subwoofer channel from the sound bar's processing, but the listing does not describe that in detail.
For buyers who want Dolby Atmos and DTS:X from a single bar, the TCL is the only product in this comparison that provides those formats. The Klipsch subwoofer cannot add Atmos or DTS:X to a non-Atmos system, and it does not process any audio formats itself. The TCL's format support is a key differentiator, while the Klipsch's format support is not applicable.
Subwoofer and Bass
The TCL A65K includes a wireless subwoofer with a Bass Boost feature, but the listing does not publish the subwoofer driver size, enclosure type, or frequency response. The total system power is up to 460 watts, but the split between the bar and the sub is not provided. In contrast, the Klipsch Flexus SUB 200 12" is a dedicated subwoofer with a 12-inch driver and 200 watts of rated power. The Klipsch listing does not publish frequency response either, so actual low frequency extension is unknown.
The Klipsch subwoofer is designed for low end duty only, and it supports connecting two subwoofers to smooth room peaks and nulls, according to the listing. The TCL listing does not mention support for a second subwoofer. The Klipsch's 12-inch driver is likely larger than the TCL's bundled subwoofer driver, but the TCL listing does not specify its subwoofer size, so this cannot be confirmed. The Klipsch's 200 watts are dedicated to the subwoofer alone, while the TCL's 460 watts are for the entire system.
For buyers who prioritize deep, room-filling bass and already own a Klipsch Flexus sound bar, the SUB 200 12" is a focused upgrade. For buyers who want a simple out-of-box system with a wireless sub included, the TCL A65K provides a bundled solution with a Bass Boost switch but unknown low frequency limits. The Klipsch product's ability to pair two units could be an advantage in larger rooms, but only within the Flexus ecosystem.
Connectivity and TV Setup
The TCL A65K is designed as a primary TV speaker and lists HDMI eARC and USB as its physical inputs. eARC allows connection to a compatible TV and passes audio from the TV's built-in apps and connected sources back to the soundbar. The listing also lists Bluetooth for wireless streaming from phones or tablets. The Klipsch Flexus SUB 200 12" has no HDMI, no eARC, and no USB inputs because it is not a soundbar. Its only wireless connection is a proprietary Klipsch transport link to Flexus sound bars only.
Setting up the TCL involves connecting the soundbar to the TV via HDMI eARC or using Bluetooth, placing the wireless subwoofer in the room, and running AI Sonic Auto Calibration. The listing does not state whether there is an HDMI input for external sources or only eARC output, but it mentions HDMI eARC and USB. The Klipsch subwoofer setup is limited to pairing with a Flexus CORE 100, 200, or 300 sound bar. The listing does not mention an app or manual controls for the subwoofer, so setup likely relies on the sound bar.
For a direct TV connection without an AV receiver, the TCL is the only choice. The Klipsch subwoofer cannot connect to a TV by itself and requires a specific Klipsch sound bar as the master unit. This makes the TCL far more flexible for general home theater use. The Klipsch is a companion product for an existing system, not a standalone connectivity hub.
Features, Apps and Voice Control
The TCL A65K lists AI Sonic Auto Calibration as a feature, which suggests automatic room correction using a microphone, but the listing does not describe the app or remote. It has Bang & Olufsen tuning, which is a brand-level audio tuning claim. No voice assistant support is mentioned. The Klipsch Flexus SUB 200 12" does not list an app, remote, or voice assistant support. Its listed features are a low latency transport technology and support for two subwoofers.
The TCL's calibration feature is a meaningful setup aid because it can adjust the sound to the room without manual measurement. However, without a published app or remote design, users cannot know how to access settings, switch inputs, or adjust bass levels. The Klipsch subwoofer appears to have no user-facing controls beyond pairing, since the listing does not mention volume, phase, or crossover adjustments. Any control likely resides in the Flexus sound bar app or remote, which is not detailed.
For buyers who want a self-contained soundbar with automatic calibration, the TCL offers that on paper. For buyers who want a subwoofer with manual tuning options, the Klipsch listing does not provide enough information to confirm those controls exist. Both products have gaps in their feature documentation, but the TCL has at least one clear user-facing feature in AI Sonic Auto Calibration. Voice control is not claimed for either product.
Design and Fit Under a TV
The TCL A65K is a soundbar, so its design intent is to sit in front of or under a TV. However, the listing does not publish dimensions, so buyers cannot verify whether it will fit their specific TV stand or wall mount. The Klipsch Flexus SUB 200 12" is a subwoofer, not a soundbar, so it is not designed to fit under a TV; it is placed on the floor. The listing does not publish its dimensions or weight either, but it does claim a small footprint relative to the 12-inch cone size.
The TCL's physical appearance is not described beyond its driver configuration and Bang & Olufsen branding. The Klipsch's only physical detail is that it houses a 12-inch driver in a cabinet described as having a small footprint. Without dimensions, both products carry fit risk, but the TCL's risk is about TV stand clearance and wall mounting, while the Klipsch's risk is about floor space and subwoofer placement.
For a buyer with limited console space under a TV, the TCL may be the intended product type, but its unknown dimensions prevent confirmation. The Klipsch subwoofer will not take up space under a TV, but it will occupy floor area, and the listing does not state its size. If under-TV fit is critical, contacting the manufacturer for TCL dimensions is necessary before purchase. The Klipsch is less likely to conflict with a TV stand, but its footprint is still unknown.
Who Should Buy It
The TCL Design Bang Olufsen A65K is best for buyers who want a single soundbar package with Dolby Atmos, DTS:X, a dedicated center channel, dual up-firing height drivers, a wireless subwoofer, and automatic room calibration. It suits users who want to connect directly to a TV via HDMI eARC and do not need rear speakers or a complex receiver setup. The lack of Wi-Fi and multiple HDMI inputs means it fits simpler streaming-centric setups. Its Bang & Olufsen tuning adds brand appeal for those who value that heritage.
The Klipsch Flexus SUB 200 12" is strictly for owners of a Klipsch Flexus CORE 100, 200, or 300 sound bar. It is a matched wireless subwoofer upgrade that adds a 12-inch driver and 200 watts of dedicated low frequency output. Buyers who already have a Flexus sound bar and want more bass depth or smoother room response with two subwoofers should consider it. No one else should buy this product, because it cannot work with other sound bars or TVs.
The two products serve completely different buyer journeys. One is an all-in-one entry into Atmos from a branded TV maker's soundbar line, the other is an accessory for an existing Klipsch system. A buyer who does not own a Flexus sound bar cannot use the Klipsch subwoofer at all. A buyer who wants an all-in-one solution should look at the TCL.
The Deciding Question
The deciding question is simple: are you shopping for a complete soundbar system or an add-on subwoofer for a Klipsch Flexus sound bar? If you need a soundbar that decodes Atmos and DTS:X, includes a center channel and height drivers, and connects to your TV through eARC, then the TCL A65K is the only reasonable option from these two. The Klipsch cannot serve as a primary speaker or connect to a TV on its own.
If you already own a Klipsch Flexus CORE 100, 200, or 300 sound bar and you are happy with its soundbar performance but want more low end, then the Klipsch Flexus SUB 200 12" is designed for you. The second question is whether you need dual subwoofers. The Klipsch supports pairing two units, while the TCL listing does not mention this capability.
The TCL's inclusion of a wireless subwoofer may be enough for most living rooms, but its subwoofer driver size and frequency response are not published, so bass extension is uncertain. The Klipsch's 12-inch driver is a known size and its 200 watt rating is dedicated, but its actual output is also unpublished. The deciding question resolves to ecosystem and product type before any performance comparison.
Who Should Buy Which
Choose the TCL Design Bang Olufsen A65K if you want a single soundbar solution with 3.1.2 channels, Dolby Atmos and DTS:X, Bang & Olufsen tuning, AI Sonic Auto Calibration, and a bundled wireless subwoofer. This is for buyers who are replacing TV speakers or an older soundbar and want a straightforward eARC connection without an AV receiver. It also suits those who value automatic room calibration and do not need rear speakers.
Choose the Klipsch Flexus SUB 200 12" only if you already own a Klipsch Flexus CORE 100, 200, or 300 sound bar and want a matched wireless subwoofer with a 12-inch driver and 200 watts. It is also a good choice if you want to run two subwoofers in a larger room and your Flexus sound bar supports that feature. The product is not a general purpose subwoofer and will not work with any other sound bar or TV.
If you do not own a Flexus sound bar, the Klipsch subwoofer is not an option, so the TCL becomes the default in this comparison. If you own a Flexus sound bar and already have decent bass, the TCL would require replacing your entire soundbar and is not compatible with your Flexus system. The two products do not compete for the same buyer in most cases; they are complementary to different setups.
