Bassjump is a subwoofer designed to enhance your built in Macbook speakers by providing mid and low frequencies. It is designed to be small and portable. It is also decidedly designed to combat the clutter one finds in other solutions (whereby, they mean the wires and cables of a traditional computer speaker set). As one who loved the simplicity and sound of my original design iMac and iSub solution, this looks like a the next logical progression for a current day setup.
