The Samsung HW-Q990D doesn’t differ wildly from the HW-Q990C. But it would be hard for the brand to cram any more speakers into this flagship soundbar combo with its wireless rear speakers and separate subwoofer. It’s an immense system.
It remains the most immersive soundbar system you can buy, based around a main unit, wireless subwoofer and wireless rear speakers that combine to create an 11.1.4-channel soundstage thanks to a total of 22 drivers, all powered by 656W of amplification.
