Does the HW-Q990C include rear speakers and a subwoofer?

Yes. The system ships as a main bar, a wireless subwoofer and two rear speakers with up-firing drivers, giving the 11.1.4 layout.

Does it support Dolby Atmos and DTS:X?

Yes. It decodes both Dolby Atmos and DTS:X, and the height channels come from up-firing drivers in the bar and rear speakers.

No. It works with any TV over HDMI eARC. Q-Symphony, which adds the TV's own speakers, requires a compatible Samsung TV.

The rear speakers connect wirelessly to the bar for audio but each needs its own power outlet.

Yes. It has Wi-Fi, Bluetooth and AirPlay 2, so you can stream from phones and other devices.

It handles music well, but reviewers say dedicated hi-fi systems sound more refined for stereo listening.
