Tang Band W4-1052SD 4" Driver 4 Ohm
A neodymium-powered 4" driver, this unit offers great bass extension and a smooth frequency response. The unique ultra-thin polypropylene cone maintains strength via special ridges in the cone, while having a very low moving mass. A long voice coil, rubber surround, and phase plug allow good use of this drivers 3.4 mm of Xmax. 4 ohm impedance is great for automotive use or high-sensitivity designs.
