Sony Black Hi-Res 7.1 Sound Bar With Wireless Subwoofer Package - HT-ST9

Create an instant home audio system with this Sony Hi-Res 7.1 sound bar. It recreates the effect of a full 7.1-channel system so that you feel as though you're actually in the movie or at a sports event, and the wireless subwoofer lets you place the bass almost anywhere within the room for maximum effect. It's easy to set up, thanks to the three HDMI-in channels that ensure you can connect multiple devices, including DVD players and consoles, to this Sony sound bar at once.

Even better, this 7.1-channel sound bar has powerful digital signal processing to produce three-dimensional sound, and it's compatible with Dolby Atmos technology so that you get true 7.1-channel sound processing for compatible audio streams. In addition, wireless multi-room playback lets you connect to it and then play audio via Bluetooth or Wi-Fi. It also has a 4K pass-through feature that copes with high-resolution video streams without affecting image quality. When you want seriously powerful sound, this Sony Hi-Res 7.1 sound bar outputs up to 800W for high volumes and maximum fidelity.
