16.5 cm woofer with black fiberglass membrane, metal basket, and robust rubber surround. Thanks to a perfected selection of materials and adhesives, the speaker can be used even under extreme environmental conditions, such as intense heat or cold, providing the necessary bass foundation. The computer-optimized suspension geometry, focused on achieving a large excursion while maintaining a compact size, allows for enormous sound pressure levels without the fear of sudden limitation. This makes the W 165 A - 2 Ohm the perfect companion, especially when it comes to high durability.
