Give your TV sound an Atmos boost

The HW-QS730D adds excitement to everything you watch with a speaker-packed bar and Dolby Atmos decoding. This 3.1.2-channel sound bar system features dedicated up-firing drivers for immersive overhead sound effects. There's a compact subwoofer included, too, which adds deep bass impact to match the on-screen action.

This sound bar system rocks movie night, but it also comes with a variety of music streaming options to make listening to your favorite tunes easy. And gamers get Game Pro Mode, which automatically tracks directional sounds to match what's happening in the game world, including overhead effects, for a smooth gaming experience.

Complementary design

The HW-QS730D's Atmos sound is a great match for Samsung's sharp-looking TVs. It works especially well with their QLED models, letting you control and adjust the settings for both the TV and the sound bar with your Samsung TV's remote. And Samsung's Q-Symphony feature lets the bar and your compatible TV's speakers play together for even bigger sound. (Q-Symphony requires a wired connection between the bar and TV.)

It also supports wireless Dolby Atmos. You can pass an Atmos signal from a compatible 2022-2024 Samsung TV via Wi-Fi for cinematic home theater sound with less cable clutter.

    Soundbar & Sub Features

    Immersive Surround Sound: The Samsung HW-QS730D is capable of delivering wireless 3.1.2ch Dolby Atmos & DTS:X surround surround, when connected to a compatible 2022-2023 Samsung TV via WiFi. Simply use the SmartThings app (for Apple iOS and Android OS) to wirelessly connect the HW-QS730D to your compatible Samsung TV over WiFi. It also supports up to 3.1.2ch Dolby Atmos & DTS:X via HDMI 2.1 eARC. In addition, Dolby Digital (5.1ch), Dolby Digital Plus (7.1ch), Dolby TrueHD (7.1ch), DTS (5.1ch), DTS-HD (7.1ch), and DTS-HD Master Audio (7.1ch) are all supported.

    • Dolby Atmos: With Dolby Atmos (includinig Atmos Music) sound comes alive from all directions, including overhead, to fill your home theater with astonishing clarity, power, detail, and depth. Rather than being constrained to channels, sounds exist as individual entities that are precisely placed and moved in three-dimensional space. A new sensation of height immerses you in the action, creating a full audio atmosphere and realistically depicting objects moving overhead. Dolby Atmos renders everything from dialogue to quiet scenes to whirlwind action with astonishing clarity, richness, detail, and depth. It all comes together in sound that excites your senses and inspires your emotions to deliver the full impact of entertainment.
    • DTS:X: DTS:X is the next generation object-based, multi-dimensional audio technology from DTS. Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich, realistic and immersive soundscape - in front of, behind, beside and above the audience - more accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the speaker layout that best fits your space.

    Note: Dolby Atmos and DTS:X is only supported using the soundbar's HDMI 2.1 eARC jack. Your HDMI connected TV must also support Dolby Atmos and DTS:X. In addition, the movie or music content must have a Dolby Atmos or DTS:X soundtrack.

    Active Soundbar Speaker: The HW-QS730D is a 3.1.2ch active soundbar speaker with dedicated front, center, and height channels so you get sound that virtually moves and flows all around you for a captivating, three-dimensional audio experience. The soundbar consists of 8 total drivers and a built-in 160 watt amplifier. The left and right front channels, along with the center channel each consist of a front-firing dome tweeter and front-firing cone woofer; while the left and right height channels each consist of a cone driver. Each tweeter receives 10 watts of power, while the three front-firing woofers receive 30 watts of power and the two upfiring drivers receive 20 watts of power.

    Wireless Powered Sub: The included wireless powered sub receives its low-frequency audio signal wirelessly from the soundbar via 2.4GHz transmission. There are no cords to connect, except the AC power cord. The wireless powered sub features a side-firing 8" woofer inside a bass-reflex cabinet with a rear-firing port. The woofer is powered by a built-in 160 watt amplifier.

    Optional Wireless Surround Kit: Turn the Samsung HW-QS730D into a complete surround sound system with optional rear Samsung speakers (SWA-9500S; sold separately) without the mess of wires for a cinematic experience. Together, the HW-QS730D and Samsung rear speaker kit, creates a 5.1.4 channel system for a truly immersive Dolby Atmos and DTS:X surround sound experience. The SWA-9500S Wireless Surround Kit consists of two wireless powered rear speakers. Each wireless powered rear speaker does have to be connected to an AC wall outlet.

    Sound Modes: The Samsung HW-QS730D soundbar speaker system offers several different sound modes that can be used with a variety of content.

    • Adaptive Sound: The Q800D soundbar analyzes the sound signal to automatically deliver optimized sound based on each scene. Adaptive Sound lets you hear voices clearly at the lowest volumes, so even the most quiet conversations are heard.
    • 3D Surround: The 3D Surround mode delivers a more realistic and immersive audio experience by adding depth and spaciousness to the movie soundtrack. From nearly any corner of the room, the 3D Surround mode blankets the listening area both sideways and up to screen level for a more immersive surround effect.
    • Game Pro: Connect your gaming console (Xbox one, PS4, Nintendo Switch) and compatible 2022-2023 Samsung QLED TV to the Samsung Q-Series soundbar to boost your gaming experience. Game Pro Mode delivers optimized sound, while offering clear directional sound to gain the advantage.
    • Stereo & All Stereo: Select Standard mode if you simply want to enjoy 2ch stereo playback through the soundbar & sub. You can also choose to play stereo sound (not surround sound) through the soundbar, optional rear speakers, and sub for a larger music space.
    • Private Rears: This mode sets the sound to come out from the optional surround speakers only, without the soundbar or subwoofer, for a smaller music space.

    Sound Technologies: The Samsung HW-QS730D offers advanced sound technologies to make sure the soundbar system sounds great in any room.

    • SpaceFit Sound Pro: SpaceFit Sound Pro analyzes your listening space using the soundbar's built-in microphone and provides optimal sound for your particular room. The result, is room-filling sound calibrated and optimized to your exact listening space.
    • Active Voice Amplifier (AVA): Active Voice Amplifier (AVA) technology helps to emphasize the voices in each scene so you can hear every line of dialog more clearly.
    • Q-Symphony: Q-Symphony synchronizes select 2021-2023 Samsung QLED TV speakers with the Q-Series soundbar speakers for fuller, more immersive, cinematic sound. This feature requires an HDMI, Optical, or WiFi connection (not supported by Bluetooth). Compatible 2021-2023 Samsung QLED TVs include the Q60, Q70, Q80, Q85, Q90, Q800, Q900, Q950, and Frame TV series.

    Audio Settings: The Samsung HW-QS730D soundbar system provides various audio adjustments to customize your listening experience.

    • Voice Enhance: Voice Enhance amplifies dialog and vocals in movie and music soundtracks so they can heard better over sound effects and instruments.
    • Night Mode: Night Mode compresses the dynamic range of the movie or music soundtrack, so there is less volume difference between soft and loud passages when watching late at night.
    • Equalizer: You can independently adjust the system's Bass & Treble (-6 to +6), or you can go a step further and adjust the system's 7-band EQ (150, 300, 600, 1.2k, 2.5k, 5.0k, 10.0k Hz) from -6 to +6.
    • Channel Level: You can independently adjust the volume level of the center, top, surround, and subwoofer channels from -6 to +6.
    • AV Sync: AV Sync can be used to help sync video to audio when connected to a TV. Video may look slower than the audio if it is connected to a digital TV. If this occurs, you can adjust the audio delay time to match the video. You can adjust the AV Sync from 0 to 300ms.

    Power Requirements: The active soundbar speaker and the wireless powered subwoofer will both have to be plugged into an AC power outlet or surge protector (sold separately). The active soundbar and wireless powered sub each include a detachable 5' AC power cord (C7, 2-prong).

    HDMI, Optical, & Bluetooth

    HDMI 2.1: The Samsung HW-QS730D's soundbar is outfitted with one HDMI 2.1 input and one HDMI 2.1 output (eARC compatible). The HDMI input allow you to connect your Ultra-HD Blu-ray player or cable/satellite box directly to the soundbar and then from its HDMI eARC output to your flat-panel TV. The HDMI input and output support 4K Pass-Through, HDCP 2.2, HDR, and eARC.

    • 4K Passthrough: The soundbar's HDMI 2.1 input and output support 4K ultra-HD video; as well as 1080p, 1080i, 720p, and 480p video.
    • HDCP 2.2 Compliant: The soundbar's HDMI input and output also support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission.

    HDR Video: HDR delivers a much higher level of contrast between light and dark to produce an image that is more realistic and closer to what the content creator imagined. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. The HW-QS730D supports HDR10 and HDR10+.

    • HDR10: HDR10 is an open standard and currently the most popular HDR format on the market. It supports 10-bit color and 1,000 nits. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
    • HDR10+: Samsung Electronics and Amazon Prime Video announced the entire Prime Video HDR library is now available in HDR10+, a new open standard that leverages dynamic metadata to produce enhanced contrast and colors on an expanded range of televisions. Prime Video is the first streaming service provider to deliver HDR10+ content to its users. The HDR10+ technology on Prime Video incorporates dynamic metadata that allows the Samsung QLED TV to adjust brightness levels on a scene-by-scene or even frame-by-frame basis. By applying individualized tone mapping to each scene, HDR10+ delivers an incredible viewing experience. The picture quality offers an enhanced visual experience with more detailed expressions, brighter shadow areas and more accurate color renderings that stay true to the creator's original intent.

    Note: This soundbar system is not compatible with HLG or Dolby Vision HDR formats.
