Powerful sound for your next party

Samsung’s MX-ST50B Sound Tower was designed specifically for music in party environments, indoors or out. When plugged into AC power, its built-in amplifier delivers 240 watts for hearty volume. When operating on battery power, it adjusts its output to 90 watts for longer playback time. Two sets of built-in drivers fire at an angle from one another, generating a wide area of sound coverage. Plus, this speaker is IPX5-rated, meaning it can withstand splashes coming at it from all sides. So go ahead: charge up the built-in 18-hour battery, place it out on the deck or by the pool, and crank away!

Flexible pairing lets you share the DJ duties

You can pair up to two mobile devices at a time to the Sound Tower via Bluetooth, so you and a friend can take turns queuing up tracks and playlists. This speaker also pairs with Bluetooth-enabled TVs in case you want to give your soundtracks a boost, too. You can add a second MX-ST50B and pair the two in stereo mode, or group several Sound Towers together in Group Play mode, for even more coverage. Download the free Samsung Sound Tower mobile app to make sound adjustments and change up the light show on the fly.
