B&C 15HCX76 15" Neodymium Coaxial Speaker 60 x 40 DegreeThe B&C 15HCX76 15" coaxial speaker features a tighter high frequency coverage characteristic that focuses output and improves throw. It is also useful for stage monitor applications that demand concentrated output and minimum "spillage". The 15HCX76's exceptionally precise pattern control is attributable to a carefully engineered waveguide coupled to the large-format high frequency driver.
A single, integrated neodymium magnetic assembly provides motor force to both the low and high frequency driver sections. The 15HCX76 is especially recommended for compact bass reflex enclosures 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.
