What’s concerning Sony HT-CT800 vs Sony HT-X9000F, I was glad that the speakers located on each side of the soundbar provide clear sound in the mid and high frequency ranges, and the wireless subwoofer makes the bass sound rich and bright. S-Force PRO Front Surround technology simulates the atmosphere of a movie theater with ambient sound and makes it possible to feel at the very epicenter of the film's events. Support for HDMI ARC (Audio Return Channel) allows you to connect to a TV with one cable, and three HDMI inputs provide the freedom to connect to various devices. The Soundbar HT-CT800 is compatible with the HDCP 2.2 copy protection standard, which supports the latest 4K formats. It has 2.1 built-in channels and 650W power output.
Comparing Sony HT-X9000F vs HT-CT800 I found out that the Sony HT-X9000F is a 2.1-channel soundbar with support for Dolby Atmos/DTS: X and Vertical Surround Engine technology that blends perfectly with BRAVIA TVs not only in quality but also in design. With the Sony HT-X9000 Vertical Surround Engine, the latest surround sound technology, you can enjoy the thrill of the latest audio formats in movie theaters such as Dolby Atmos and DTS: X in one slim package. No matter what room you are in, the three front speakers reproduce “vertical”, creating a virtual surround sound that seems to come from you.
