The Samsung HW-Q700C has four up-firing drivers: there are two directly on the bar as well as two on the Samsung SWA-9500S satellites, which bounce sound off of your ceiling and back at you to give you the impression of height. The frequency response is also balanced, ensuring sound effects sound clear.
Additionally, we subjectively evaluated this bar's Atmos performance. Overall, this setup creates dimensionality in your audio, but it doesn't sound quite as immersive as that from the Samsung HW-Q990D. The surround speakers are quite subdued, so you'll want to boost them by one or two notches to help get a better response. Otherwise, some sound effects, like the sound of drones passing overhead, fall short of giving you a sense of range.
