The WR-4 can be used as either a midrange or midbass driver. It can be crossed as low as 80 Hz or as high as 5,5500 Hz. This unusual driver uses a 2.1" diameter voice coil on a 4" cone. The powerful neodymium magnet system is vented for and open sound and the hexagonal shaped aluminum voice coil wire allows for high power handling.
