True to its name, the TDK V513 Wireless Sound Cube is a compact Bluetooth wireless speaker in the shape of a cube, measuring 9 x 9 x 9 inches. The speaker features a 2.1 channel configuration that incorporates four full range drivers, two passive radiators and a subwoofer. With an omni-directional and directional mode, you can select sound direction for the best audio possible. You can also adjust bass and treble to further customize your sound.

For devices like a tablet or smartphone that don't have Bluetooth capability, you can connect them to the V513 using its 3.5mm auxiliary input. There is also a USB port for charging your devices as you listen to music. The charging port outputs a generous 2.1 amps of power for compatibility with power-hungry devices like an iPad. Additionally, the speaker comes with a remote control so you can change tracks and adjust volume from across the room. A top carrying handle allows for portability.
