Kube4 plays your favorite tunes the way they were intended — with deep bass and true highs. It plays balanced sound without distortion even when you crank it all the way up.

With a very high output, up to 101dB SPL, Kube4 pumps out sound like a live rock band. Whether you're at the beach, on a boat or in the backyard, Kube4 is made to fill wide open spaces with life-sized sound. Kube4 also has a high frequency range — from below 50Hz to 20kHz.

Connect a wireless microphone and you have an instant PA system right at your fingertips. Perfect for events and meetings, or any time you want to hold the audience's attention.

Turn your Kube4 on and press play — that's it. No wires. No cables. No outlets. Kube4 works with one simple connection using WiFi or Bluetooth on your smartphone, tablet, or laptop. Get access to our advanced features like multi-room and multi-stream experiences. You can also connect Kube4 with Spotify and AirPlay 2.0, no app needed!

Stay connected with up to 40 hours of battery life. You can start the party on the spot and keep it going all day and night.

When you receive your Kube4, download the KubeSync app from the mobile app store to use on iOS and Android. Use the KubeSync app to stream music, choose speakers, configure stereo channels, or adjust the volume and other settings.

With Airplay 2.0 or the KubeSync app, you can connect up to 32 Kube4 speakers to create a multi-room music experience. You can play music in sync across the whole house, or choose to use the KubeSync app for multi-channel functionality and stream different songs for different spaces.

With painted marine grade plywood, sealed enclosures, and passive radiators for the bass, Kube4 is weather resistant. The sophisticated materials and seamless construction makes Kube4 highly durable with a rating of IPX5.

This means the speaker can resist a sustained, low-pressure water jet spray, and you can take Kube4 on the water or in the snow. It stands up to humidity, rain, snow, dust, salt spray, UV rays, and extreme heat and cold.

Nathan George and his friends noticed that music has become small, convenient, and personal. Although music is intimate, it has become very isolated and constrained. They wanted to create a product that lets music be big, bold, and shared — a product that sets music free. The Kube Sound team shares a simple but meaningful idea that music should complement space, not compete with it. To bring this vision to life, they called upon the best in engineering, design, and manufacturing. Audio experts united not only by their drive for perfection but also by their love for music. The result is Kube4, a portable speaker designed for the outside world. The team likes the sound of it, and they think you will too.
