B&C's 6NDL44 6-1/2" cast frame neodymium woofer is a lightweight, powerful choice for ultra-compact multi-way speaker systems. Its rubber half-roll edge and treated cone are engineered to handle high bass excursions without drama, while still allowing a clean, articulate sonic signature. The 6NDL44 is also suitable as the midrange element in medium efficiency 3-way applications.
