Once tinny and underpowered, the latest speaker systems have many useful features such as subwoofers that add guts to everything you hear, convenient volume controls, plenty of power and compact designs that won't chew up your desk space. Good speakers make everything you hear more enjoyable. No more crawling behind the box to hook up your speakers. Loads of volume for even large groups.
