NSD4015Ti2 is a 1.5 inch exit neodymium compression driver designed for extremely high quality, high output sound system applications. Featuring a four inch copper-clad aluminum voice-coil and dome, the pure titanium membrane with integral surround has been optimized for high sensitivity and efficiency and an extended high frequency region. While maintaining a broad piston band and low distortion the results are maximum sound output with natural sound character and exceptional clarity up to the highest end of the frequency spectrum.
