The Dayton Audio PC83-4 full-range driver features a woven fiberglass composite diaphragm, rubber surround and a powerful motor. The design allows for very good diaphragm control, low inductance and a significant reduction in distortion, improving the high frequency response. The performance of this model is very good over the entire frequency range, with a controlled off-axis response and high efficiency. It is especially ideal for the design of small format loudspeakers.
