Designed with the help of award-winning Hollywood sound engineers, this 450-watt system delivers full-range, Dolby TrueHD sound with the plug-and play simplicity of 3 HDMI inputs, plus Bluetooth audio for one-touch audio streaming from your Android or IOS mobile device. No other sound bar even comes close. Engulf yourself in an immersive 7.1 channel sound experience With 9-individual speaker drivers, including integrated front and center channels plus dedicated tweeters, all powered by 7-discrete digital amplifiers, the ST7 delivers a great, balanced, detailed sound. The ST7 hits the acoustic sweet spot for everyone in the audience providing for a perfect listening experience, while the surround sound works its way seamlessly around you and your home. 3 HDMI connections Get superior high-definition picture and sound quality from up to three high-definition source devices (ex. Cable box, Blu-ray player, gaming console, etc), all of which can be conveniently plugged in ST7. Connect stream music from Bluetooth devices with just one-touch The easiest and fastest way to start streaming music from your NFC enabled device to your home theater system. Near Field Communication lets you connect and wirelessly stream music from your smartphone or tablet by touching them together just once. No NFC, no problem. Thanks to Bluetooth, you can still connect and stream music from your smartphone, tablet, or computer. Any time, any place Hear your sound instead of seeing it. The wireless sub-woofer delivers incredible heart pounding bass, and, because it's wireless, it can be placed anywhere in the room. The wireless subwoofer is also front-firing, so it compliments the bar for a seamless sound, while the down-firing passive radiator subwoofer helps deliver a bold and powerful low-frequency range. True Theater Sound Since movies are created with detailed soundtracks, shouldn't your sound bar be able to represent them the way they were created to sound? Working with award winning sound engineers for Sony Pictures Entertainment, we were able to design the ST7 to more faithfully represent the sound characteristics you would hear in a theater. Experience movies as the directors intended them to sound with Dolby TrueHD and DTS-HD Master Audio code support. You're Surrounded Experience room filling cinematic simulated surround sound with Sony's S-Force Front Surround sound technology. The ST7 delivers a powerful surround sound effect without the need to connect multiple speakers throughout the room. Additional Features: Magnetic Fluid Speaker technology In conventional speakers, dampers provide suspension and stability for voice coils, which unfortunately create unwanted noise and distortion. By eliminating speaker dampers and replacing them with magnetic fluid speaker technology, energy efficiency is dramatically improved, and mids and highs are extended in incredible detail and clarity, for a more accurate revealing sound, in addition to cranking out 1.6 times the volume of a conventional speaker.
