Among the many products that Sony is introducing at CES 2018 are three Sony Soundbars. Two of them, the HT-Z9F and HT-X9000F (seen above), come with a wireless subwoofer and support Dolby Atmos and DTS:X immersive audio without ceiling reflection or extra speakers.

How do they do it? With a technology Sony calls Vertical Surround Engine. Unfortunately, no details about how it works is included in the press release, so I hope to learn its secret during the show. Combined with Sony's S-Force Pro Front Surround technology, which is said to improve the apparent conventional surround sound, the result is a truly immersive soundfield.

The Z9F has a native channel configuration of 3.1, but it can "upmix" 2-channel content to 7.1.2. If you really want physical surround speakers, you can add the SA-Z9R kit. The X9000F is 2.1 natively, but it can also create a Dolby Atmos immersive soundstage using Vertical Surround Engine. In addition, it's designed to aesthetically match the new X900F LCD TVs.

Both of these Sony soundbars support 4K HDR10 and Dolby Vision passthrough. Also, the Z9F supports high-resolution audio formats, and it can enhance non-HRA files with its DSEE HX (Digital Sound Enhancement Engine).

Connectivity includes two HDMI inputs and one HDMI output, USB, and Bluetooth. The Z9F also provides Wi-Fi and Chromecast built-in, and you can control it using voice commands with Google Assistant using a smart speaker such as the Google Home.

According to Mike Fasulo, President and COO of Sony Electronics, North America, "At Sony, we are committed to creating optimal listening and viewing experiences for our consumers as well as a stunning design. Our new HT-Z9F and HT-X9000F Dolby Atmos sound bars with virtual three-dimensional sound enable consumers to be surrounded by a truly impressive TV experience while looking great in your living room."

Giles Baker, SVP, Consumer Entertainment Group, Dolby Laboratories, is also bullish on the new Sony soundbars. "Dolby continues to execute on its mission to bring Dolby Atmos to more people, in more places, through more form factors. With the launch of these new Dolby Atmos sound bars, we're bringing immersive, lifelike sound to even more of Sony's lineup."

The HT-Z9F will be available in the Spring for a list price of $900. The HT-X90000F will hit the shelves at the same time for $600.

Another new Sony soundbar is the 2.1-channel HT-S200F. This compact model includes a built-in subwoofer, and it incorporates S-Force Pro Surround Sound to expand the soundfield beyond its diminutive cabinet. Connections include HDMI ARC (Audio Return Channel), USB, and Bluetooth.

The HT-S200F will be available in the Spring, but pricing has not yet been disclosed.
