LG SC9S vs JBL Bar 700
Quick Verdict
Choose the LG SC9S if you own an LG OLED evo C Series and want a matched, mountable Dolby Atmos bar with clear dialogue, a wireless subwoofer, and integrated TV features like WOWCAST and WOW Orchestra. Choose the JBL Bar 700 if you want true 5.1 surround with detachable battery powered rear speakers, a 10 inch subwoofer, and built in Wi-Fi with AirPlay and Chromecast. The LG prioritizes height effects and LG ecosystem integration. The JBL prioritizes physical surround and published power output. Both soundbars have significant specification gaps around HDMI and dimensions.

Sound Quality
Both soundbars score 24 out of 30 for sound quality, but they achieve that score in different ways. The LG SC9S uses a 3.1.3 channel configuration with dedicated triple up-firing drivers for height effects. This layout suggests an emphasis on overhead Dolby Atmos audio and a front soundstage with a center channel for dialogue. The JBL Bar 700 uses a 5.1 channel configuration with detachable surround speakers, which may deliver a wider soundfield for movies. The difference in channel count reflects different design priorities, with LG focusing on height and JBL focusing on true rear surround.
The LG SC9S includes Clear Voice Plus, which is listed as a feature that emphasizes dialogue intelligibility. This can help with TV shows and movies where voices get lost in effects. The JBL Bar 700 lists 620 watts of total system power, which suggests louder output, but power alone does not guarantee clarity. The LG listing does not publish power or driver sizes, and the JBL listing does not publish driver sizes or frequency response. Both models lack detailed acoustic measurements, so a direct sound comparison is limited to published features.
AI Room Calibration Pro on the LG tailors output to the room, which may benefit irregular spaces. The JBL Bar 700 does not list room calibration in its pros or specs. However, the JBL Bar 700 has a 10 inch subwoofer and higher published power, which may produce more dynamic range. Neither model publishes total harmonic distortion or crossover settings, so buyers cannot fully judge audio precision from the listings. On paper, the LG emphasizes clarity and height, while the JBL emphasizes power and physical surround channels.
Surround, Atmos and Audio Formats
The LG SC9S is Dolby Atmos certified and uses triple up-firing drivers to create height effects. DTS support is not stated in the listing. The JBL Bar 700 supports Dolby Atmos and lists no DTS support either. Both bars therefore cover the most common immersive audio format but may lack DTS compatibility for some Blu-ray or streaming content. This gap is identical for both, so Dolby Atmos is the primary immersive codec on paper.
The JBL Bar 700 has a true 5.1 layout with detachable battery powered surround speakers. These physical rear channels can place sound behind the listener, which up-firing bars often simulate but not as convincingly. The LG SC9S can expand later through Rear Speaker Ready, but the listing does not specify which rear speakers are compatible or if they are included. In its base form, the LG relies on acoustic reflections for rear effects, while the JBL provides actual rear speakers out of the box.
LG includes WOW Orchestra, which pairs the bar with compatible LG TV speakers to add height or width. This is a unique integration not available on the JBL. However, WOW Orchestra requires a compatible LG TV. The JBL Bar 700 works with any TV over HDMI or optical, though the listing does not specify the exact inputs. For buyers who want out of the box physical surrounds, the JBL is stronger. For LG TV owners who want an integrated Atmos setup, the LG is more tailored.
Subwoofer and Bass
The JBL Bar 700 includes a 10-inch wireless subwoofer, which is a concrete published spec. A 10-inch driver can typically move more air than smaller units, producing deeper bass. The total system power of 620 watts suggests the subwoofer has substantial amplification, though the listing does not separate subwoofer power from the bar and surrounds. The LG SC9S includes a wireless subwoofer, but its driver size, power, and enclosure volume are not published in the listing.
The LG listing does not provide any bass output specifications or frequency response. This makes it difficult to compare low frequency extension. The JBL listing also lacks frequency response, but at least the 10-inch driver and 620 watt total power give some indication of capability. For buyers who prioritize bass impact, the JBL Bar 700 appears stronger on paper due to the larger listed driver and total power.
Both subwoofers are wireless, which reduces cable clutter. Neither listing states wireless range, pairing method, or whether additional subwoofers can be added. Without measured bass output, the comparison remains incomplete. On published specs, the JBL Bar 700 has a more clearly stated bass advantage, while the LG SC9S subwoofer remains an unknown quantity.
Connectivity and TV Setup
The LG SC9S features WOWCAST built-in for wireless Dolby Atmos from compatible LG TVs. This can eliminate the need for an HDMI cable between TV and bar, but only with certain LG televisions. The listing does not publish HDMI eARC or input details, so the number and type of physical connections are unknown. There is also no Bluetooth or Wi-Fi spec stated for the SC9S. Setup appears optimized for LG TV owners who can use WOWCAST.
The JBL Bar 700 lists built-in Wi-Fi with AirPlay, multi-room music streaming, and Chromecast built-in. This provides streaming and multiroom options out of the box. However, the JBL listing does not publish HDMI eARC or input details either. Buyers cannot confirm how many HDMI inputs, whether eARC is supported, or if there is an HDMI passthrough. This is a significant gap for both soundbars.
In TV setup, the LG includes an OLED Synergy Bracket for compatible LG OLED evo C Series models, making physical mounting clean and matched. The JBL Bar 700 does not mention any bracket or wall mount kit. However, its detachable surround speakers reduce the need for long cable runs. Both bars require some form of audio connection to a TV, but without published HDMI details, buyers may need to rely on optical or the wireless options listed. The LG is more TV specific, while the JBL is more generalist with Wi-Fi streaming.
Features, Apps and Voice Control
The LG SC9S includes WOW Interface, which allows control through a compatible LG TV remote. The listing does not state a dedicated soundbar app for the SC9S. This means setup and adjustments may be limited to the TV menu on compatible LG sets. The LG also includes AI Room Calibration Pro, Clear Voice Plus, and Rear Speaker Ready. These features are controlled somehow, but the exact interface is not detailed.
The JBL Bar 700 listing does not publish remote, app, or voice assistant details. It supports AirPlay, multi-room music streaming, and Chromecast built-in, which are streaming protocols rather than full voice control. The Bar 700 does not list a built in microphone for voice assistants. Voice control might be possible through connected devices, but the listing does not confirm this.
Neither soundbar lists a dedicated companion app in its published specifications. The LG leverages the LG TV remote via WOW Interface, which is a streamlined approach but only for LG TVs. The JBL offers more wireless streaming flexibility through Wi-Fi and Chromecast, but lacks published control details. Buyers who value app based customization will find both listings incomplete, though the JBL's streaming support is more explicitly stated.
Design and Fit Under a TV
The LG SC9S includes the LG OLED Synergy Bracket, designed for LG OLED evo C Series televisions. This bracket allows the bar to attach directly to the TV, but it may not fit other TV models. The LG listing does not publish dimensions or weight, making it hard to verify if the bar fits in front of a TV on furniture. The bracket suggests a seamless look with the specified C Series.
The JBL Bar 700 listing does not publish dimensions or weight either. The bar includes detachable battery powered surround speakers, which adds flexibility for placement around a room. Without dimensions, buyers cannot confirm if the main bar fits under their TV stand or if it blocks the TV's infrared sensor. Both soundbars suffer from missing physical specifications.
The LG's design is clearly tailored for LG C Series owners, with a matching bracket and likely aesthetic. The JBL's design is more focused on creating a wire free 5.1 system, with the main bar plus two battery powered surrounds. Battery life for the surrounds is not published, which affects real world usability. For under TV installation, the LG's bracket is a concrete advantage for the right TV, while the JBL's dimensions remain unknown.
Who Should Buy It
The LG SC9S is best for owners of LG OLED evo C Series televisions who want a matched soundbar with clean mounting and TV integration. Its triple up-firing drivers, Clear Voice Plus, and WOW Orchestra are tailored for that ecosystem. Buyers who already use the LG TV remote will appreciate the WOW Interface. The SC9S is also a good option for those who want height-heavy Atmos effects without adding rear speakers immediately.
The JBL Bar 700 is best for buyers who want true 5.1 surround sound without running speaker wires. The detachable battery powered surround speakers create a physical rear soundstage, which up-firing bars cannot fully replicate. Its 10 inch wireless subwoofer and 620 watts of total power appeal to those who want strong bass. Built in Wi-Fi with AirPlay and Chromecast adds streaming convenience to non LG setups.
Both soundbars suit different priorities. The LG is an integration play, while the JBL is a self-contained surround package. Buyers outside the LG ecosystem may find the JBL more versatile because its core features do not require a specific TV brand. Buyers with the matching LG C Series will get a cleaner installation and extra audio integration through WOW Orchestra. The right choice depends on your TV and your surround preferences.
The Deciding Question
The deciding question is whether you value a matched LG TV experience or a true 5.1 wireless surround system. The LG SC9S offers WOWCAST, WOW Orchestra, and a C Series mounting bracket. These features are excellent for LG OLED evo C Series owners but less relevant for others. The JBL Bar 700 includes physical rear speakers and a large subwoofer out of the box, making it a more conventional home theater soundbar.
Another key factor is specification transparency. The JBL publishes total power and subwoofer size, but omits HDMI details, driver sizes, dimensions, and DTS support. The LG omits power, driver sizes, HDMI details, and dimensions. Both listings have gaps, but the LG's feature set is more ecosystem dependent. If you cannot verify connections and fit, you may need to consult additional sources or seller support.
For LG C Series owners, the LG SC9S is the natural choice because the WOW features are exclusive and the bracket ensures a clean install. For everyone else, the JBL Bar 700 offers a more complete surround package with physical rear speakers and streaming, assuming the missing connectivity details do not cause issues. The decision ultimately hinges on your TV brand and how much you want physical surrounds versus integrated height effects.
Who Should Buy Which
Choose the LG SC9S if you own an LG OLED evo C Series. The built-in WOWCAST provides wireless Dolby Atmos, and the included OLED Synergy Bracket attaches the bar directly to the TV. Clear Voice Plus improves dialogue, and AI Room Calibration Pro tunes the sound for your space. The triple up-firing drivers deliver height effects without added rear speakers, and WOW Orchestra uses the TV's speakers for a fuller front stage.
Choose the JBL Bar 700 if you want true 5.1 surround with minimal wiring. The detachable battery powered surround speakers place sound behind you, creating a more enveloping effect than virtual or up-firing alone. The 10-inch wireless subwoofer and 620 watts of total system power suggest strong low end. Built-in Wi-Fi with AirPlay, Chromecast, and multi-room music support adds streaming options that do not depend on a specific TV brand.
If you are not tied to LG and want the most complete out of box surround package, the JBL Bar 700 is the safer choice, assuming its missing HDMI details are acceptable. If you already own a matching LG C Series and want a seamless, mountable Atmos upgrade, the LG SC9S offers unique integration that the JBL cannot match. Both bars have specification gaps, so confirm fit and connectivity before buying.
