Our Verdict
Samsung HW-Q900A
Samsung HW-Q930B
The Samsung HW-Q930B is better than the Samsung HW-Q900A for most uses. The Q930B comes with rear speakers, meaning it provides a much more immersive sound with surround sound formats like Dolby Digital. It reproduces more low-bass out-of-the-box, too, and its Atmos performance is better. If you don't have space for rear speakers in your setup, the Q900A is a good alternative.
