B&C 12CL76 12" Neodymium Woofer
The CL Series stamped metal frame woofers feature performance similar to B&C's lightweight HPL Series, but at a significantly lower price. They are aimed at the OEM builder, for a wide variety of applications including premium quality plastic speaker cabinets, bass guitar enclosures, or any cabinet that can benefit from a significant reduction in weight. The CL Series offers an excellent alternative to similar performance ceramic magnet drivers.

B&C cone loudspeaker models range from 6.5" to 21", each built on a sturdy die-cast aluminum or stamped steel chassis for maximum mechanical reliability. Voice coils are wound in two layers inside-outside around polyimide or fiberglass formers, giving them the ability to withstand very high thermal stress. Loudspeaker cones are treated with a special stiffening finish, resulting in excellent rigidity and avoiding break-up problems when driven to full power.
Many B&C speakers include carefully balanced copper or aluminum rings that minimize variations in the magnetic field during operation, reducing distortion and increasing accuracy in reproduced sound. Most models also feature a specially designed cooling path through the magnet assembly to further increase power handling and lower power compression. The NDL, NW, HPL, and NCX models use powerful neodymium magnets that offer a weight reduction of up to 60%, and special chassis designs for improved cooling.
The design and optimization are performed with up-to-date Finite Element Analysis (FEA) to obtain the best combination of efficiency, linearity, and thermal exchange. Ongoing research and refining of the theoretical models and a constant updating of the measurement methods and instruments allow B&C to further increase excursion capabilities, consistency, and overall sound quality.
