Samsung HW-Q930C vs Samsung HW-Q800D

The Samsung HW-Q930C is an expanded 9.1.4 version of the Samsung HW-Q800D and comes with an additional two satellite speakers for a better surround performance. They share a similar build quality, and the bar and sub look virtually identical. They perform very similarly when it comes to stereo frequency response, height, dynamics, and center, but the Q930C has a notable advantage when it comes to the soundstage and surround sound, as the audio sounds wider and more immersive. If these factors aren't important to you, both bars feature similar connectivity options and can passthrough 4k signals at 60Hz, though neither is HDMI 2.1 compatible.
