The W5-1685 5" midbass features a long throw, underhung 1-1/2" voice coil driven by a massive 33 oz. ferrite magnet. A shorting ring on the polepiece is responsible for the speaker's extremely low levels of second and third order harmonic distortion. This impressive motor is coupled to an optimized paper cone with rubber surround, supported by a cast aluminum frame. The driver's naturally high and smooth upper frequency rolloff facilitates simplified crossover designs.
