The BassJump 2 from Twelve South is a subwoofer specifically designed for the MacBook Pro and Air. It’s a USB-powered portable subwoofer that converts your MacBook into a full-fledged sound system. The single USB cable delivers both sound and power to the subwoofer. The Bassjump 2 software combines the sound from the MacBook’s speakers with the low frequency bass from the subwoofer, giving you an enhanced experience such as one might expect in a surround sound system at a cinema hall. At the very least, it’ll clear the clutter of speakers and cables off your desk without in any way effecting the high-quality sound you are used to. A retro preferences window with two analog VU meters allows you to customize the sound to rock, pop or your very own personal brand of music.
