For today’s edition of Deal of the Day, Amazon has the JBL Duet Speaker System for Portable Music and PC for just $29.99. That’s 50% off the speakers’ usual retail price of $59.99.

The JBL Duet multimedia speaker system provides smooth and accurate sound for any portable music player or computer. With its incredibly easy setup and use, Duet is a sophisticated approach to achieving great two-channel sound.

Duet uses patent-pending Tangential Strain Relief (TSR) technology that was designed specifically to deliver extra bass and lower distortion in small enclosures as a result of controlled linear excursion of the speaker. It also provides superior midrange- and high-frequency reproduction.

The neodymium magnet creates more power and sensitivity. Duet also uses a proprietary Adverse Pressure Gradient (APG) port design, which greatly enhances the bass performance.
