Upgrade to Smooth and Immersive 3D Sound

If superb sound quality and easy operation are at the top of your soundbar wish list, the LS-B50 is the way to go. AuraSphere digital signal processing works with a six-channel amplifier, powerful wireless subwoofer, and eight-driver speaker array to seamlessly replace TV audio with rich and enveloping 3D sound. There are three sound modes to optimize 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 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.

Panoramic 3D Sound with AuraSphere DSP

The LS-B50 is powered by AuraSphere Digital Signal Processing (DSP) 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.

Pre-Programmed Sound Modes
Movie Mode

Onboard AuraSphere technology applies custom EQ filters to get the most out of movie and game soundtracks. Deeper bass and an open mid-range carry dialog clearly, all enhanced by AuraSphere's panoramic 3D soundfield.

Music Mode

For music, you want plenty of punchy bass, that doesn't drown out vocals and strings. AuraSphere manipulates the EQ and sound pressure levels to best suit music playback, while expanding the soundfield so that you enjoy balanced stereo sound no matter where you're sitting.

News Mode

This sound mode makes dialog more intelligible and maintains clean, balanced response for all types of content, including TV programs, movies, and news. With this mode engaged, you won't have to keep raising the volume to hear what's going on. The LS-B50 simply makes TV sound clear and rich.

High Quality Audio Decoding

Dolby Digital is a high quality audio format commonly encoded on DVDs, Blu-ray Discs, and in TV broadcasts. Compatible TVs can pass Dolby Digital audio through to the LS-B50 for richly detailed playback enhanced even further with your choice of AuraSphere sound mode.

Obeys Your TV's Remote

The LS-B50 comes preprogrammed with IR codes for nine major TV brands (and learning capability for others), which means it switches on automatically with your television and responds to your TV remote volume commands.

For everyday use, the LS-B50 is set-and-forget, seamlessly replacing flat-screen sound with immersive TV audio.

Stream Your Audio with Built-In Bluetooth

Pair your cellphone, smartphone, tablet, or PC to the LS-B50 and stream wirelessly via the onboard Bluetooth technology. From your smartphone's music apps (like Spotify, SoundCloud, and other internet radio services) to locally stored libraries, Bluetooth technology streams content quickly and easily, and the LS-B50 reproduces the sound faithfully and powerfully. Your podcast binges will sound amazing!

Easy, Flexible Installation

The LS-B50’s low-profile design makes it ideal for displaying on an entertainment unit or TV stand. The unit’s flat back panel and shallow depth allow for easy wall mounting as well. The included IR flasher makes controlling the LS-B50 simple no matter where it's placed.

With amplified power firing downwards through a big 6 1/2in. (16cm) cone, the included wireless active subwoofer does an excellent job of adding impact to your favorite content, from games to music to movies. 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.
