Stewart Audio USB-SP

The fully-integrated USB-SP was designed by Stewart Audio to provide big sound even when you're on-the-go. The full-range speaker boasts an integrated high-efficiency Stewart Audio amplifier capable of running off of a standard USB outlet. With its small size and built-in universal mounting clips, the entire unit will easily fit on the lid of most notebook computers. However, don't let the size fool you, the USB-SP can fill a boardroom or classroom with ease. Tough enough to throw in your bag, the USB-SP is a portable workhorse that stands up to Stewart Audio's reputation of providing clear, crisp audio in places other products fall short.
