 Speaker Driver Subwoofer 15W 4 Ohm 76dB 55Hz-2kHz Ø7.6cm

The Tang Band W3-1876S is a small subwoofer with a diameter of only 7.6cm, ideal for integration into compact speakers. In spite of its compactness, the W3-1876S provides a solid reproduction of low frequencies. It uses a neodymium magnet motor, a santoprene suspension and a polypropylene diaphragm, capable of a large travel of ±5mm.
