The Invoke features best-in-class audio with an incredible 360-degree audio experience. The product has superior specifications, coming with 40W of power, 3 tweeters, 2 woofers and 2 passive radiators. This creates superior sound performance, without distortion, everywhere in your room. Now, with the introduction of the Cortana voice assistant, Invoke customers can experience premiere sound with an unprecedented voice interaction experience. The UI reduces button complexity with a beautiful, semi-transparent touch-panel that reveals a diffusive lighting effect. The curved profile draws the eye up to celebrate this lighting effect.
