Our Verdict
Samsung HW-Q990D
Samsung HW-Q800D
The Samsung HW-Q990D is Samsung's flagship 2024 11.1.4 soundbar. Unlike the Samsung HW-Q800D, which is just a bar with a subwoofer, the HW-Q990D comes with discrete satellites that help with surround sound formats like Dolby Digital and Atmos. Although the two have a similarly balanced sound, the HW-Q990D also has a better height performance and can get louder with minimal compression at max volume. Gamers will also appreciate the HDMI 2.1 compatibility and ability to passthrough 4k signals at 120Hz. All in all, the HW-Q990D is a more complete soundbar that's worth the additional outlay if you have the space for it.
