Samsung vs LG Soundbar 2026: Which TV Soundbar Is Better?

The LG S80QY 3.1.3ch Soundbar with Wireless Subwoofer is LG's mid-range Atmos soundbar—3.1.3 channel configuration (three front channels, one subwoofer, three upward-firing channels for Dolby Atmos height) at a price point that delivers measurable spatial audio for Dolby Atmos and DTS:X encoded content on streaming services and Blu-ray. The wireless subwoofer handles the bass frequencies that the soundbar's drivers cannot produce, eliminating the floor-shaking resonance from mounted wall speakers. LG's MERIDIAN audio engineering partnership is the brand differentiation—Meridian Audio is a high-end British audio company, and the LG-Meridian partnership brings audio engineering input to LG's soundbar lineup that pure electronics brands lack. The soundscape algorithm that MERIDIAN contributes to the upward-firing Atmos processing provides more natural height audio than purely algorithmic processing. Against Samsung soundbars on this page, LG's S80QY with Meridian is the mid-range Atmos comparison—real object-based height audio for 3D sound at the mid-price tier. Samsung's Q600C at similar pricing provides comparable Atmos channel count at different acoustic tuning. The head-to-head comes down to TV ecosystem integration: LG soundbars have seamless eARC and ARC sync with LG TVs (volume, input, power control through a single HDMI cable); Samsung soundbars similarly integrate with Samsung TVs. Cross-brand pairing works but loses some synchronization features.

The Samsung HW-Q600C 3.1.2ch Soundbar with Dolby Atmos is Samsung's mid-range Atmos soundbar—3.1.2 channel configuration (one fewer upward-firing channel than LG's S80QY 3.1.3 channel) providing Dolby Atmos height audio at the mid-price tier. Samsung's SpaceFit Sound technology analyzes the room's acoustic characteristics at setup to calibrate the soundbar's EQ and virtual sound processing to the specific room dimensions, improving the out-of-box sound accuracy without manual calibration. The Q-Symphony feature synchronizes the soundbar's audio output with a compatible Samsung TV's built-in speakers, using the TV speakers as additional audio channels for wider soundstage than the soundbar alone produces. This Samsung-specific feature is a meaningful advantage for Samsung TV households, creating a virtual 5.1+ system from the TV and soundbar combination. Against LG S80QY, Samsung's Q600C provides the Q-Symphony TV integration for Samsung households and the SpaceFit Room Calibration that LG doesn't include at this tier. For Samsung TV owners, the Q-Symphony integration is the practical differentiator that justifies Samsung-branded soundbar purchase over LG or other brands.

The Samsung HW-B550 2.1ch Soundbar with Dolby Audio is Samsung's entry-level soundbar—2.1 channel (stereo soundbar plus wireless subwoofer) without Atmos height channels, at $150–200 for buyers who want wireless subwoofer bass improvement over TV speakers without the complexity and cost of Atmos processing. The 2.1 configuration covers standard TV audio upgrade needs: clearer dialog, better music reproduction, and bass extension from the wireless subwoofer. For the majority of TV audio improvement needs, 2.1 soundbar performance delivers the perceptible upgrade from TV speakers that buyers are seeking—Atmos height channels become meaningful specifically for Atmos-encoded streaming content in a room with adequate ceiling height, which is a subset of soundbar use cases. The HW-B550's 410W power output provides living room volume without needing to push the system to distortion. Against the Samsung HW-Q600C above, the B550 is the value-focused recommendation for buyers who don't specifically want Atmos or who are upgrading a bedroom or secondary TV rather than a dedicated home theater. The wireless subwoofer makes it complete out of the box without additional speaker purchases. Against LG S40Q at similar pricing, the Samsung HW-B550 provides comparable 2.1 channel performance at marginally different pricing based on retail timing.

The LG S40Q 2.1ch Soundbar with Wireless Subwoofer is LG's entry-level soundbar—the 2.1 channel base configuration matching Samsung's HW-B550 tier for buyers who want an LG-branded audio upgrade to their TV. The AI Sound Pro feature analyzes audio content type (movie dialog, music, sports commentary) and adjusts the EQ profile automatically, providing the acoustic optimization that manual EQ presets require active user engagement to achieve. The wireless subwoofer pairing provides the same bass reinforcement benefits as Samsung's entry-level wireless subwoofer—eliminating the wire run from soundbar to subwoofer that makes speaker placement more complex. LG's MERIDIAN audio engineering input, present in higher LG models, is not featured at the S40Q tier; the S40Q uses standard LG audio processing. For LG TV owners at the entry-level soundbar tier, the S40Q provides the seamless ARC/eARC integration with LG TVs that makes volume control and input switching simple from the TV remote. Against Samsung HW-B550 at competitive pricing, LG's S40Q with AI Sound Pro provides slightly more intelligent audio adaptation; Samsung's SpaceFit is present only in the Q-series. For buyers without TV brand loyalty, the choice between the two 2.1 entry soundbars is often driven by current pricing at retail.
