Speaker Driver Full Range 15W 4 Ohm 85dB 100Hz-20kHz Ø6.3cm
The Dayton Audio ND64-4 is a full-range loudspeaker, capable of a large linear excursion of 6mm peak-to-peak. It features a dual neodymium magnet structure, a 19mm diameter CCAW voice coil and a copper tube to minimize distortion. The neodymium motor is combined with a rigid yet lightweight aluminum-magnesium diaphragm for a dynamic and punchy sound. The ND64-4 is perfect for use in single driver speaker designs as well as in multi-way speakers.
