Samsung's HW-Q90R soundbar is the flagship model of 2019 among similar devices with an additional subwoofer. The uniqueness of this soundbar is that the Samsung HW-Q90R specs contain Dolby Atmos and DTS: X. More info in this Samsung HW-Q90R review.
The main feature of the Samsung HW-Q90R is support for Dolby Atmos and DTS:X (and their variants). However, what distinguishes it from other “bars” that you saw earlier is the ability to deliver these object audio formats using a genuine 7.1.4-channel setting, rather than resorting to acoustic radiation or psychoacoustics. The speakers are divided into 12 channels: front left and right, center, two sides, two rear parts, two front heights, a pair of rear heights and a subwoofer. All these speakers are equipped with a built-in amplifier with a power of 512 W, and the claimed frequency response of the system is from 34 Hz to 17 kHz.
Despite its size, the HW-Q90 manages to remain modest in appearance. You will need a lot of space to place it under the TV, but if this is a problem, there is also the possibility of wall mounting. There is a simple LED display that lights up when the soundbar receives a command, providing basic information. In the upper central part of the soundbar there are several controls for turning on and off, selecting inputs and adjusting the volume. A small and inconspicuous screen is hidden behind the speaker grill, so when watching movies it does not distract. On the other hand, the font size on the screen is well readable.
As for the connections, there are two HDMI inputs and an output, each of which supports 4K / 60p, 4: 4: 4, Rec.2020, wide dynamic range (HDR10, HLG, HDR10 and Dolby Vision), 3D and HDCP 2.2. This should ensure that Samsung can handle anything. Thanks to a recent firmware update, the HDMI output now includes eARC, which allows lossless sound to be transmitted from a compatible TV. This is a common complaint, but the two HDMI inputs seem stingy considering the price.
Like most other Samsung products, SmartThings is supported - it simplifies setup and allows you to control the soundbar along with other connected devices from the same hub.
