B&C's 21SW152 features a massive 260 square inches of diaphragm surface area, nearly 40% more than an 18" driver and equal to double the Sd of a typical 15". A 6" diameter voice coil with a 1" copper winding length provides great Xmax (15 mm) and impressive power handling (2,000 watts RMS). Despite the driver's size, a high-strength neodymium ring magnet keeps overall weight as low as possible. The 21SW152 will deliver nearly unmatchable low frequency output when loaded into vented or horn loaded enclosures. Perfect for high output concert and nightclub applications.

B&C Speakers

B&C cone loudspeaker models range from 6.5" to 21", each built on a sturdy die-cast aluminum 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 which 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.
