Upgrade to Smooth and Immersive 3D Sound

If superb sound quality and easy operation are at the top of your soundbar wish list, take a look at the LS-B50 from hi-fi specialists Onkyo. AuraSphere digital signal processing works together with a six-channel amplifier, powerful wireless subwoofer, and eight-driver array to seamlessly replace TV audio with rich and enveloping 3D sound. There are three sound modes to optimize for movies, dialog, or music, and Bluetooth technology for wireless playback of almost any audio source sent from smartphone, tablet, and PC. This soundbar is very easy to install, with just a single cable to connect and a wireless sub you can place almost anywhere. It even comes with a wall-mounting kit and an IR flasher for placement on an entertainment unit under your flat-screen display. Best of all, the LS-B50 turns on automatically and responds to volume commands from the TV remote, making it exceptionally easy for people of all ages to enjoy.

The LS-B50 is powered by AuraSphere DSP (Digital Signal Processing) technology. It works by optimizing driver output to create a 3D surround effect from stereo sources. Unlike other DSP technologies, AuraSphere expands the sweet spot (the area in front of the TV where audio sounds best) to create a 3D soundfield that places the listener in the center of the action, wherever they’re sitting.

AuraSphere is a listening experience technology developed jointly by Onkyo Corporation and Sonic Emotion ag.

Flexible Set-Up with Wireless Subwoofer

The powerful 16 cm wireless down-firing subwoofer included with the system does an excellent job of adding impact to your favorite games, movies and music. The crossover is set to blend perfectly with the soundbar, creating a deep, seamless audio image no matter where you choose to place the cabinet.

Stream Music from Smartphone, Tablet, and PC

It’s easy to listen to music and other audio programs, too. Simply pair your cellphone, smartphone, tablet, or PC to the LS-B50 soundbar and stream wirelessly using the inbuilt Bluetooth technology. From your smartphone’s music apps (such as Spotify, SoundCloud, and internet radio services) to locally stored libraries, Bluetooth technology lets you enjoy content quickly and easily.
