Onkyo  HT-S5800 5.1.2 Dolby Atmos 4K Home Theater System

Part #: ONKHTS5800  |   Mfg #: HT-S5800

Adrenaline Pumping Home Theater Sound

Dolby Atmos is the next (r)evolution of home theater audio - an immersive 3D dimensional surround sound experience that creates a breathtakingly realistic and captivating sonic atmosphere.

Top Shelf Speaker Performance

Durable two-way bass reflex front speakers with 5" mid-range drivers and balanced-dome tweeters ensure accuracy of sound, while the upper region of the speaker cabinets contain up-firing 3¼" cones for playback of Dolby Atmos soundtracks - all of which are independently powered by the receiver's height channels. These are not simply 'FX' channels, but true separately mixed audio channels. Add to that a center speaker designed specifically for dialog clarity and a bone-shaking 120 watt subwoofer with a huge 10" cone for thunderous bass impact.

4K Ultra HD Ready

Built to support HDMI 2.0 and HDCP 2.2 for future proof compatibility with your Blu-Ray and digital content, the HT-S5800 can stream 4K video up to 18Gbps in the 4:4:4 color space.
