Hi Sandy - The MX-T70 Sound Tower provides you with 1500W of bi-directional sound as well as bass from the built in 10" subwoofer; you can further enhance the bass by pressing the Bass Boost button as well. With the Sound Tower App, you can control the LED lighting, sound effects, and your EQ settings from your Android or iOS device. You can connect up to 10 Samsung Sound Tower devices wirelessly, and Bluetooth Multi-Connection allows you and your friend to connect and pair two mobile devices simultaneously without disconnecting. ^Gina
