The 21SW152 is a subwoofer with a nominal diameter of 21" (530 mm), with a neodymium magnet and a powerful 6" (153 mm) voice coil. It represents one of the highest industrial standards available today. The construction structure of this subwoofer involves the use of an elegant and massive painted aluminum basket, combined with a powerful ventilated neodymium magnet. The driving force that pushes the voice coil is generated by a neodymium capsule set inside the magnetic complex, capable of generating a magnetic flux of 1.20 T. Furthermore, the characteristic force factor of this speaker reaches the impressive value of 39 Tm! Furthermore, the structure of the magnet incorporates an aluminum demodulating ring (ADR technology).
