Hello Ali87! The Q800F is the newer model, and while both the Q800D and Q800F feature the same 5.1.2-channel setup with Dolby Atmos and DTS:X, there are a few key differences.
Sound quality for movies and series is excellent on both — you’ll get immersive surround sound, clear dialogue, and powerful bass either way. However, the Q800F offers upgrades, including improved wireless connectivity (Bluetooth 5.2), added support for streaming features like Chromecast built-in and AirPlay 2, and a newly designed and compact subwoofer.
If you're deciding between the two, the Q800F is the better long-term pick, especially for smart home integration and streaming flexibility.
