Main trade-off
Klipsch Flexus Core 100
Three-inch height can block a low screen. There is no Wi-Fi music or separate HDMI source input.
Head-to-head
Klipsch Flexus Core 100 vs Sonos Beam Gen 2: Core 100 can keep your wired sub, Beam fits a lower screen
The short answer
Core 100 can reuse a compatible wired powered sub, while Beam is narrower and 0.32 inch lower. Pick Core 100 when that sub and a Bluetooth music routine already work for you. Pick Beam for Wi-Fi music, compatible Sonos expansion and a lower cabinet. Beam’s Trueplay tuning requires a compatible iPhone or iPad, and neither bar adds HDMI source inputs.
Before you choose
The reasoning and the trade-offs
The cheaper whole-system choice can depend on the sub you already own
For someone downsizing an older receiver setup into a small apartment, a working powered sub may be the one piece worth keeping. Core 100 has a wired RCA sub output, while Beam expands through compatible Sonos subwoofers. If the existing sub has a suitable line-level RCA or LFE input, Core 100 can avoid another bass-box purchase. That advantage disappears if the old sub is passive, uses only a proprietary wireless connection or has no suitable input. Check the actual unit before comparing the two bars’ Amazon offers. The useful total is the equipment needed to complete your setup, not the price of a soundbar that leaves part of it unusable.
What this is based on
Documented output and ecosystem compatibility crossed with replacing an older system in a smaller room. No universal cost or acoustic advantage. Existing sub must be powered and input-compatible.
Main trade-off
Sonos Beam (Gen 2)
No generic RCA powered-sub output. Trueplay needs compatible iOS hardware.

About this comparison
Core 100 vs Beam Gen 2 for a compact TV, an old powered sub and shared-home music. Check screen clearance, expansion costs and iPhone-only tuning.
Both are compact standalone bars with virtual Atmos and optional expansion. They suit the same small-TV buyer but differ in what existing equipment and household devices can stay useful.

What matters in practice
The differences that matter
The cheaper whole-system choice can depend on the sub you already own
For someone downsizing an older receiver setup into a small apartment, a working powered sub may be the one piece worth keeping. Core 100 has a wired RCA sub output, while Beam expands through compatible Sonos subwoofers. If the existing sub has a suitable line-level RCA or LFE input, Core 100 can avoid another bass-box purchase. That advantage disappears if the old sub is passive, uses only a proprietary wireless connection or has no suitable input. Check the actual unit before comparing the two bars’ Amazon offers. The useful total is the equipment needed to complete your setup, not the price of a soundbar that leaves part of it unusable.
How we reached this conclusion
Documented output and ecosystem compatibility crossed with replacing an older system in a smaller room. No universal cost or acoustic advantage. Existing sub must be powered and input-compatible.
A fraction of an inch can matter more than the Atmos badge
If a small TV sits low on its original feet, Core 100’s compact width does not guarantee it clears the picture or remote sensor. Its three-inch height is 0.32 inch above Beam’s 2.68 inches. A measured gap between those heights can make Beam the practical fit without raising the TV or changing furniture. Both rely on virtual height presentation, so neither should be chosen on the assumption that the Atmos label means dedicated upward-firing height drivers. Measure the screen and sensor separately, and leave room behind the bar for its plugs. If there is less than 2.68 inches of usable clearance, neither cabinet resolves that placement as measured.
How we reached this conclusion
3 minus 2.68 = 0.32 inch. Conditional geometric fit, not a promised remote-control result or recommendation to use an unstable TV riser.
A shared-room feature can have a phone requirement hidden behind it
Beam is attractive when the TV room also handles Wi-Fi music for the household. Its Trueplay room-tuning process, however, requires a compatible iPhone or iPad. An Android-only household should separate the supported music features from that tuning requirement before buying. Beam also lets you disable touch controls in the app, useful when a child or pet repeatedly touches the top of the bar. Core 100 offers app sound adjustments and Bluetooth music without promising an equivalent room-measurement system. Neither choice guarantees clearer speech for a listener with hearing difficulties, and control locking is not a child-safety feature.
How we reached this conclusion
Sonos device-specific tuning and documented touch-control setting crossed with shared-home music and accidental operation. No inference that undocumented Klipsch control locking is absent.
Try your real numbers
Will the soundbar fit under your TV?
Measure the clear space in front of your TV. Count devices you want to plug into the soundbar, not devices already connected to the TV. The numbers below are examples until you enter yours.

Use an open top surface, not an enclosed cubby. Detachable speakers are counted in the docked width. Allow extra depth for cables and the TV stand. This checks physical dimensions and port counts, not Dolby Atmos, 4K/120Hz passthrough or your TV’s audio-format support.

Meaningful differences
What changes the fit
| What changes | Klipsch Flexus Core 100 | Sonos Beam (Gen 2) | Why it matters |
|---|---|---|---|
| Cabinet clearance | 28 × 3 × 5 inches | 25.63 × 2.68 × 3.94 inches | Beam is 2.37 inches narrower and 0.32 inch lower, which can matter at a screen edge. |
| Existing powered sub | RCA powered-sub output | Compatible Sonos sub expansion, no RCA sub output | Core 100 can preserve a suitable conventional sub that Beam cannot directly accept. |
| Music routine | Bluetooth playback, no Wi-Fi music | Wi-Fi streaming and AirPlay | Choose around the household’s sources and services, not only film playback. |
| Room setup and controls | App adjustments including Dialog Boost and Night Mode | Trueplay on compatible iOS, Night Sound and optional touch-control disable | Beam tuning has a device prerequisite. Its control lock can avoid accidental taps. |
| HDMI source ports | None, TV eARC connection only | None, TV ARC or eARC connection only | A crowded TV input panel remains a separate problem with either choice. |
What you give up
Every choice has a cost
If you choose Klipsch Flexus Core 100
- An old proprietary wireless or passive sub is not made compatible by the RCA socket.
If you choose Sonos Beam (Gen 2)
- Plan for compatible Sonos expansion rather than assuming an existing sub or rear pair will connect.
Recommendation switch
The decision flips if...
A compatible existing powered sub is part of the plan
Choose Klipsch Flexus Core 100. The RCA output can keep it useful.
Wi-Fi music or the lower cabinet solves the room constraint
Choose Sonos Beam (Gen 2). Beam adds those benefits, with separate tuning and expansion requirements.
What matters in practice
Before you choose
You want a smaller TV setup without replacing a good subwoofer or tying a shared-room feature to a phone you do not own.
What this comparison cannot tell you
- No measured dialogue, isolation, bass or neighbor-noise advantage is established. Night listening modes do not guarantee that sound will stay within the room.
