The HT-S7705 is one of the first complete speaker packages to offer Dolby Atmos compatibility, providing everything one would need for a future-proof, next-generation home entertainment system. 

The HT-S7705 utilises Onkyo's prestigious and well-known high current discrete amplification experience and pairs this unit with a package of Dolby-Atmos enabled loudspeakers to form a multidimensional bubble of high quality, realistic sound to the latest 4K/60Hz films and games. This solid performing, yet compact and unobtrusive system includes a well-constructed subwoofer unit, driving 80W through a large 20cm cone.

This meticulous selection of loudspeakers, combined with the sonic superiority of the amplifier unit, provides an immersive sound response to enable the viewer to truly put themselves within their favourite films.

This system is not only built to provide an excellent standard of sound, but also to offer a convenient and prolific variety of listening options. A large number of integrated streaming services such as Spotify, DLNA certification, AUPEO! and Bluetooth are built in to the unit, meaning that the HT-S7705 system is not only great for films and games, but also for casual music listening.

There’s even a phono input to connect your turntable and USB for lossless audio. Graphical menus are overlaid via HDMI® and there’s a choice of preprogrammed or smartphone remote control, making this package a snap to set up and use. If there was ever a time to bring multiplex entertainment home, that time is now
