B&C Speakers 12HCX76 12" Neodymium Coaxial Speaker NEW! AUTHORIZED DISTRIBUTOR!



  • B&C 12HCX76 12" Neodymium Coaxial Speaker 60 x 40 Degree

A single, integrated neodymium magnetic assembly is shared by the B&C 12HCX76 12" coaxial speaker's low and high frequency driver sections. When deployed, a 12HCX76 is capable of accurate pattern control and excellent projection, thanks to its carefully engineered waveguide coupled to the large-format high frequency driver.

The 12HCX76's high efficiency and accuracy make it especially suitable for compact bass reflex enclosures, stage monitors, and long-throw ceiling applications like hotel ballroom installations. Crossover not included. Recommended 12 dB/octave crossover frequency: 1,200 Hz.

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.
