uStream Cube
Meet the uStream Cube, a compact bookshelf/desktop speaker system designed to bring full hi-fi stereo into your home without the mess of wires. Each Cube is an identical active speaker. Switch them on and they automatically pair — no app, no Wi-Fi, no cable between left and right. Just seamless stereo.
Why Choose the Cube
Real stereo sound
Wide, immersive soundstage with sturdy bass, smooth mids, and crisp highs.
Soundbar killer
Place Cubes either side of your TV via HDMI ARC or aux and hear a true cinema effect instead of the flat sound of a bar.
Smart home ready
Works as a default playback device for Amazon Alexa or Google Home. Control by voice for hands-free stereo.
No subwoofer needed
Proprietary 4″ magnesium-alloy driver with 20oz neodymium magnet delivers bass far beyond its size.

Protective dust cap over mid/bass driver. No dents, no worries.
