Samsung HW-Q910B vs Samsung HW-Q930B

The Samsung HW-Q930B is better than the Samsung HW-Q910B. Although they're both Dolby Atmos soundbars with many of the same sound enhancement features, the main difference between the two bars is the satellites that are included. The Q910B's satellites lack up-firing Atmos drivers, and the resulting performance with Atmos content isn't as impressive. They have to be wired to a receiver module to work, which can be limiting depending on your room setup.
