Created exclusively for MacBook, the Bassjump enhances your laptop audio experience. The Bassjump uses a specialized software to blend requency ranges between your laptop speakers and the Bassjump’s own subwoofer. The added mid to low frequencies provided by the Bassjump bring a fuller sound to the media files stored on your laptop. A single USB cable provides both power and audio connection while also limiting the clutter typically associated with external speakers. Available at TwelveSouth.
