This compact driver design features patented symmetry suspension, which provides excellent centering of voice coil at high excursion. Integral “one-piece” Magaluma diaphragm and voice coil former design to aid cooling of the motor. The diaphragm comes equipped with special-designed rubber surround, which helps to dampen the diaphragm resonance. The basket, voice coil former and bottom plate are vented to reduce air compression and lower distortion. This product was designed with compact sound bars and portable speaker applications.
