True 5.1 physical surround vs virtual surround — the fundamental difference and when it matters
The LG S65TR's defining advantage over single-bar soundbars (including those with Dolby Atmos) is the physical placement of rear speakers behind the listening position. In a standard soundbar — even an advanced Dolby Atmos soundbar — all audio drivers are in the soundbar unit placed in front of the listener. Surround and height effects are created through psychoacoustic processing: the soundbar uses HRTF (Head-Related Transfer Function) algorithms to modify the timing, frequency response, and phase of audio signals to fool the brain into perceiving sound as coming from behind or above, even though the physical driver is directly in front. HRTF processing is sophisticated and works reasonably well for sounds above and to the sides, but it has a well-known limitation: sounds from directly behind the listener are the hardest to convincingly simulate from a front-only driver array, because the brain uses pinna (outer ear) reflections to distinguish front-from-back, and these reflections are difficult to replicate via DSP alone. The LG S65TR's wireless rear speakers physically sit behind the listening position — they produce sound that travels directly from behind and to the sides of the listener, requiring no psychoacoustic simulation. A rear-channel helicopter sound in Dolby Digital 5.1 content is reproduced by the rear-right and rear-left speakers actually behind the listener's ears — the brain detects this as coming from behind because it genuinely is coming from behind. For a household watching sports (crowd roar from all directions), gaming (footsteps from specific directions for spatial awareness), or action films (explosions in specific locations), the physical rear speaker placement of the S65TR delivers directional precision that front-only soundbars cannot match regardless of their DSP sophistication.
Dolby Digital 5.1 vs Dolby Atmos — understanding what the S65TR decodes and what it doesn't
Dolby Digital 5.1 and Dolby Atmos are both Dolby audio formats but represent different generations of surround sound technology. Dolby Digital 5.1 is a channel-based format — it encodes audio as six discrete channels (front left, centre, front right, rear left, rear right, and the .1 LFE subwoofer channel). Every audio element is pre-assigned to one of these six channels in the studio mix: a rear-channel explosion is specifically mixed to the rear-left and rear-right channels. Dolby Atmos is an object-based format — audio elements have real-time 3D position metadata rather than fixed channel assignments. Dolby Digital 5.1 is the dominant format for broadcast television, standard streaming (non-premium tiers), cable set-top box audio, and the majority of DVD content — it is the most widely available surround sound format in India's content ecosystem. Dolby Atmos is available on premium streaming tiers (Netflix premium, Apple TV+, Disney+ premium), 4K Blu-ray, and selected gaming titles. For the LG S65TR's typical use case — daily TV viewing via a set-top box, standard Netflix/Prime/Hotstar streaming, and gaming on a standard HDMI connection — Dolby Digital 5.1 is the primary surround format the user will encounter, and the S65TR decodes and renders it through its physical 5.1 speaker system. The S65TR does not decode Dolby Atmos object metadata — Dolby Atmos content will still play (as Dolby Digital Plus core or as PCM) but without the object-based height and spatial rendering that an Atmos-capable soundbar (like the Marshall Heston 120) provides from the same source. The buyer's consideration: if the primary content source is standard Indian broadcast + OTT standard tiers + gaming, Dolby Digital 5.1 with physical rear speakers delivers excellent surround. If the primary use case is premium OTT + 4K Blu-ray with Atmos tracks, the Atmos-capable Marshall becomes relevant.
AI Sound Pro — how LG's content analysis differs from manual sound mode selection
Standard soundbar sound modes (Movie, Music, Sports, Game) require the user to manually select the appropriate mode for the current content — a user watching a film switches to Movie mode, then switches to Sports mode for the match, then to Music mode for a playlist. Each mode applies a pre-designed EQ curve and surround processing preset. LG's AI Sound Pro uses real-time audio content analysis to detect and classify the content type automatically: it analyses the audio signal's spectral content, dynamic range, transient characteristics, and dialogue presence to determine whether the content is a movie, sports broadcast, news programme, music, or game. Movie content has high dynamic range with specific LFE content patterns; sports broadcasts have crowd noise with commentary dialogue; news has narrow-band speech with limited low-frequency content; music has sustained harmonic content with specific bass patterns; games have directional audio cues with high transient density. Based on this classification — updated in real time as content changes — AI Sound Pro adjusts the surround processing, EQ curve, dialogue clarity, and bass management to the optimal settings for the detected content without user intervention. The practical benefit for an Indian household's typical evening viewing pattern: news at 8pm transitions automatically to a serial at 8:30pm transitions automatically to a movie at 9pm transitions automatically to sports at 11pm — AI Sound Pro handles all four transitions without the user touching the remote.
WOW Interface — controlling the soundbar from the LG TV remote and screen
WOW Interface is LG's proprietary integration protocol between LG soundbars and LG TVs connected via HDMI ARC/eARC. When the LG S65TR is connected to a compatible LG TV, the TV's on-screen interface displays the soundbar's control options as a native menu within the TV's own settings system — sound mode selection, volume level, bass and treble adjustment, and sound profile switching all appear in the TV's familiar menu structure and can be operated using the LG TV remote without any separate soundbar remote. This eliminates the two-remote problem that affects most soundbar-TV combinations: the TV remote controls the TV, the soundbar remote controls the soundbar, and the user must constantly switch between two remotes to manage the overall audio-visual experience. With WOW Interface, the LG TV remote becomes the single controller for the complete entertainment setup. Additionally, WOW Interface enables HDMI ARC volume synchronisation — adjusting the TV's volume simultaneously adjusts the soundbar output, maintaining a unified volume control experience. For a household where multiple family members use the TV, the elimination of a separate soundbar remote reduces confusion and the risk of misplaced or lost remotes. WOW Interface is compatible specifically with LG TVs — non-LG TV users can still use the soundbar's included remote or Bluetooth/HDMI standard volume control.
