GT Audio GT-SW15/4 15'' 38cm 2x4Ohm DVC Subwoofer 300w RMS (Sealed/Ported Enclosures)

World RRP: £61.95


Product code: GT-SW15/4

High quality dual voice coil subwoofer offering performance without excessive cost. Lightweight construction for efficient performance even when powered from modest amplifiers. Extremely musical bass, by virtue of the complete lack of mass. As a subwoofer is made more and more powerful the heavier and heavier resultant cone and motor weight blunts the musicality, creating the familiar one note bass that we seem to be used to today. The GT-SW range is a breath of fresh air and delivers back that exciting, hard, driving sound. Unbeatable bass performance at the price point.
