1. Polypropylene membrane stiffened with mineral powder.
2. High excursion butyl rubber surround.
3. Deep ribbing on the surface of the cone increase rigidity.
4. Very high efficiency, with superior power handling.
5. Designed to be used in small sealed or reflex (vented) enclosures.
6. Pure copper voice coil, wound on aluminum former, for very good thermal
and mechanical capacity.
7. Venting system provides better thermal dissipation and consistent
performance.
