Samsung HW-Q910B vs HW-Q910D

The Samsung HW-Q910D is an incremental upgrade on the Samsung HW-Q910B. Despite there being a generation between them, the differences in both features and performance between these two bars are quite small. Both have balanced default frequency responses, with plenty of scope for sound enhancement. The Q910D offers an improved dynamics performance and a better center channel focus, though the older model's up-firing drivers create a slightly better perception of height in Atmos content. Otherwise, the Q910D comes with Chromecast support, and it supports FreeSync and G-SYNC passthrough, which will suit gamers. If you're okay with foregoing any of these improvements, the older model will likely be available for a marked-down price.
