SonicGear Quatro 2 Laptop/Desktop Speaker 2.0  (Yellow, Black)

Besides smooth trebles and crystal clear highs, its innovative design – which uses not one or two, but four cleverly positioned bass reflex panels – quadruples the bass. This produces a phenomenal replication of the aural experience of a 2.1 sound system, with the fullest bass lines and punchiest beats the industry has ever heard from just two micro speakers.
