Q900H

Overview

HW-Q900H is a 2026 Q-series soundbar with a 7.1.2 setup: the soundbar and a wireless subwoofer come in the box, and Samsung's SWA-9500S wireless rear speakers can be added. The soundbar is about 1232 mm wide, 71 mm high and 138 mm deep (Samsung lists 48.50 x 2.79 x 5.43 inches), and the wall-mount brackets are included. Samsung lists the colour as Titan Black and 17 speakers.

The TV connects over HDMI eARC. Two HDMI inputs pass 4K video at up to 120 Hz with HDR10+ through to the TV, and there is also an optical input, Bluetooth and Wi-Fi. Over Wi-Fi, the bar supports AirPlay, Chromecast, Spotify Connect and Tidal Connect, and it has Amazon Alexa. With some Samsung TVs it also offers Q-Symphony (TV speakers and soundbar play together), wireless Dolby Atmos over Wi-Fi and SpaceFit Sound Pro through the TV. Samsung also lists Sound Elevation and Auto Volume.

You can control it with the buttons on the bar, the included remote, the TV remote, or the SmartThings and Samsung Sound apps on iOS and Android.

What the specs mean

• 7.1.2 speaker setup: seven main channels, one subwoofer channel and two height channels from up-firing speakers, which is how the bar plays Dolby Atmos with sound from above.
• HDMI eARC: the enhanced Audio Return Channel sends the TV's sound to the soundbar over one HDMI cable, including high-bitrate formats such as Dolby TrueHD, Dolby Atmos and uncompressed multichannel audio.
• HDMI passthrough: a console or streaming box can plug into one of the two HDMI inputs; the bar passes 4K video at up to 120 Hz with HDR10+ on to the TV.
• Audio formats: Dolby Atmos, Dolby Digital, Dolby Digital Plus, Dolby TrueHD and multichannel PCM. The page also lists Eclipsa Audio. The manual notes that DTS:X may not be supported depending on the model or region.
• Room correction (SpaceFit Sound Pro): the manual says the bar analyses the listening space with its microphone and optimises the sound automatically. It is switched on from the soundbar's own remote, or from the menu of some Samsung TVs.
• Voice and night modes: Samsung lists Voice Enhance Mode and Active Voice Amplifier (AVA) Pro for dialogue, and a Night Mode for late listening.
