FEA optimized magnet assembly delivers highly symmetrical cone - movement, leading to exceptionally low harmonic distortion

Balanced Airflow Venting (BAV) on the front-plate increases airflow to provide enhanced cooling
Dual Magnet Motor (DMM) incorporates a secondary magnet used to increase overal motor force (Bl) without the need for any additional increase in magnet size

"Multi-roll" surround provides exceptional linearity at extremes of cone excursion
