Sony always makes home audio products a part of its CES presentations, and 2018 is no difference. Perhaps most notable are the HT-Z9F and HT-X9000F, two soundbars that include Dolby Atmos surround sound. Of course, true Atmos requires overhead speakers, and these are just 2.1(HT-X9000F) and 3.1 (HT-Z9F) soundbars. As such, this requires some virtualization, which happens courtesy Sony's "virtual surround engine," which the company claims can replicate the wide soundstage Atmos provides. And regardless of whether you're watching content mixed for Atmos or not, the more expensive HT-Z9F include a "Vertical S" button that Sony says will provide virtual 3D sound. The HT-Z9F will retail for $900/£600 and the HT-X9000F will cost $600/£450 when they arrive this spring.
