About the Onkyo LS-B50

Let Onkyo dress up your TV's sound

Onkyo is known for making excellent home theater receivers. But some people prefer a simpler, cleaner setup in their main TV room rather than the receiver-and-speakers approach. That's why Onkyo designed their first sound bar, the LS-B50. Its built-in six-channel amplifier and eight drivers reinvigorate TV shows, movies, and music — in bold, clear stereo or stunning virtual surround sound. The wireless subwoofer fills in those low frequencies that have been missing and presumed non-existent. Together, they'll make you wonder how you ever tolerated those wimpy little TV speakers.

Onkyo is known for making excellent home theater receivers. But some people prefer a simpler, cleaner setup in their main TV room rather than the receiver-and-speakers approach. That's why Onkyo designed their first sound bar, the LS-B50. Its built-in six-channel amplifier and eight drivers reinvigorate TV shows, movies, and music — in bold, clear stereo or stunning virtual surround sound. The wireless subwoofer fills in those low frequencies that have been missing and presumed non-existent. Together, they'll make you wonder how you ever tolerated those wimpy little TV speakers.

The right sound at the right time

Onkyo's AuraSphere technology digitally optimizes the bar's drivers to create a lifelike 3D effect with a large "sweet spot." That means dynamic, realistic sound won't be restricted to the person sitting front and center. Plus, there are three sound modes designed for different content. "Movie" mode delivers plenty of deep bass through the subwoofer for explosive sound effects, while making sure dialogue remains clear. "News" is perfect for dialogue-heavy TV watching, where soundtrack music and other effects aren't a priority. And "Music" mode digitally adjusts frequencies in the audio signal for well-balanced stereo sound when cranking up your favorite tunes.

Onkyo LS-B50 sound bar with wireless subwoofer

The LS-B50's eight front- and side-panel drivers will take your TV's sound to new heights in stereo or virtual surround sound.

Bluetooth and USB options for music

The LS-B50 offers several options to get your music playing. Connect your disc player to the coaxial digital input. Or you can use your smartphone or computer to stream music wirelessly over Bluetooth to listen to your digital music collection. Or stream tunes from music services like Spotify®, Pandora®, and SiriusXM. There's a USB port for playing digital music stored on a flash memory device like a USB thumb drive, easily controlled with the included remote.

Quick setup, easy control

The beauty of sound bars lies in their easy setup and operation. The LS-B50 is a cinch to get up and running. Place the bar on your TV stand or wall-mount it with the included kit. You can run a single optical cable (also included) from your TV into the bar. Place the wireless subwoofer anywhere you like in the room — no wires means fewer restrictions. Plug both the subwoofer and bar into a power protection device and you're ready to rock. The bar even comes pre-programmed to work with remotes for most major brands of TVs.

    Product Research


    Active Soundbar + Powered Sub System: The Onkyo LS-B50 Active Soundbar + Powered Sub System offers a simpler alternative to your typical 5.1ch home theater speaker system. Not every room can accommodate five speakers and a subwoofer; and not everyone wants to deal with hooking up rear surround speakers. The Onkyo LS-B50 is a two-piece home theater system with an amplified soundbar speaker that connects directly to your TV, Blu-ray/DVD player, or Satellite/Cable box; plus a wireless powered subwoofer that can be placed anywhere in your room. The Onkyo LS-B50 Active Soundbar + Powered Sub System adds virtual surround sound to your music or movies thanks to AuraSphere DSP (Digital Signal Processing) technology.

    • Active Soundbar Speaker: The LS-B50's active soundbar speaker features an eight driver array with two 1.1875" ring tweeters, four 2.75" full-range cone drivers on the front, and two 2.75" full-range cone drivers on each side; all powered by an internal digital amplifier. The soundbar speaker provides clear dialog and a wide soundstage. The two front-firing ports add efficiency and better midbass response to the speaker. All of the system's analog & digital inputs are found on the active soundbar speaker.
    • Wireless Powered Sub: With a down-firing 6.5" cone woofer, dedicated amplifier, and bass reflex enclosure (down-firing port), the included wireless powered 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 speaker, creating a deep, seamless audio image no matter where you choose to place the sub. You can adjust the volume level (-/+10) of the subwoofer independently from the main volume (0-30). Because its wireless, the powered subwoofer offers simplicity in terms of hookup & flexibility in terms of placement.

    Dolby Digital Decoding: Dolby Digital is a high quality audio format commonly encoded on DVDs, Blu-ray Discs, and in TV broadcasts. Select TVs can pass Dolby Digital audio from there built-in ATSC/QAM tuner and network apps through to the LS-B50 for dynamic playback, enhanced even further with AuraSphere DSP technology. You must connect the audio signal of your Blu-ray/DVD player or Satellite/Cable box directly to the soundbar speaker system to receive a Dolby Digital signal. If you route the audio signal of your Blu-ray/DVD player or Satellite/Cable box through the TV first, it will come out as PCM (2ch) at the TV's digital output; the AuraSphere DSP technology will create a virtual surround sound effect either way.

    Panoramic 3D Sound w/ AuraSphere DSP: 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. The LS-B50 offers three pre-programmed AuraSphere sound modes.

    • Movie: 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: 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: 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.

    Analog + Digital Inputs: The Onkyo LS-B50 is fitted with both analog and digital inputs to connect your external AV components. There is one optical (toslink) and one coaxial (RCA) digital input to connect up to two digital audio sources, such as your flat-panel HDTV and Blu-ray player. The digital inputs will accept PCM (2ch) or Dolby Digital (5.1ch) audio signals. There is also one analog audio minijack (3.5mm) input for connecting a portable MP3 player with a headphone jack output or a TV without a digital output.

    USB Port: The Onkyo LS-B50 features a USB (type-A) port which allows you to connect a compatible USB mass storage class device; such as select Android smartphones (Gingerbread/Froyo OS only), digital audio players, or USB thumbdrives. The unit will support music playback and basic control (play/pause & previous/next track) of MP3 music files (8-320kbps; 8-48kHz) stored on a compatible USB msc device formatted in FAT 12/16/32. The speaker's USB port will also charge your USB-enabled device while connected.

    Note: The USB port is not compatible with the Apple iPod, iPhone, or iPad.

    Bluetooth Audio Streaming: Pair your smartphone, tablet, laptop, or desktop computer to the LS-B50 and stream music wirelessly via built-in Bluetooth (ver.2.1+EDR) technology. You'll be able to wirelessly stream stored music and music apps on your Bluetooth-enabled devices to the LS-B50. You'll still use your Bluetooth-enabled mobile device for music navigation and song/artist information. Pairing is done with the press of a single button.

    Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Onkyo system.

    Remote Control: The LS-B50 features top-panel controls on the soundbar speaker and includes a wireless IR remote for operation of the system's power, volume, input source, sound mode, and USB playback controls. It also comes preprogrammed with IR codes for a variety of 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. The included IR flasher makes controlling the LS-B50 simple no matter where it's placed.

    Note: The LS-B50 is preprogrammed with IR codes for nine major TV brands; including Funai, LG, Panasonic, Philips, Samsung, Sharp, Sony, Toshiba, and Vizio, with learning capability for other TV brands.

    Mounting Options: The LS-B50's low-profile design makes it ideal for displaying on an entertainment unit or TV stand. Four self-adhesive rubber feet protect your furniture and keeps the speaker from moving. The unit's flat back-panel and shallow depth allow for easy wall mounting as well. There are two keyhole slots on the back of the speaker that are spaced 20.25" apart (mounting hardware not included). Because the system's powered subwoofer is wireless, you can position it any where in the room (within 25').

    Auto Standby: The system automatically turns on when an audio signal is output from your TV. The system automatically enters standby mode if there is no operation and no sound for approximately five minutes.
