PRV Audio's impressive 4MR60-4 4 ohm 4" full range driver is excellent for
use in portable speaker systems, line arrays, or even car audio applications.
With 91 dB efficiency and 30 watt power handling this driver is capable of
remarkable output for its size.
Highlights
Inherently damped, woven fiberglass cone
Large spider improves linearity at high excursion
Rubber surround for use in less than optimum conditions
High efficiency and power handling allows surprising output for its
size
The 4MR60-4 from PRV Audio can deliver amazingly flat response from 150 Hz
up to 7,000 Hz. With a woven cone and rubber surround, this driver is inherently
damped minimizing resonant peaks to produce a more natural sound. Capable of
high output for its size, this full range is perfect for use in small portable
speakers, larger line arrays, or even car audio systems.
