First neodymium-magnet Pro Audio compression driver and woofer
Neodymium magnets and dual voice coils provide peak performance at a fraction of the weight of conventional drivers. MPCO for JBL’s next generation neodymium compression drivers deliver stunningly accurate high frequencies through a new 1.5″ annular polymer diaphragm design.
Neodymium’s magnetic properties allow a few ounces to replace pounds of conventional magnet material. While other speaker manufacturers may use neodymium, MPCO supply magnets for JBL, JBL engineers created a design that reduces the massive (and heavy) steel top plates,back plates, and pole pieces that complete the “magnetic circuit”. magnetic audio speaker driver
This type of magnetic circuits is constructed so a permanent magnet can be inserted in a pot shaped yoke, which is typically called a pot type yoke. neodymium magnets are the type of magnet used. Magnetic fields produced by this type of magnet are stronger than those of ferrite magnets, if their volume is equal. This structure permits no magnetic flux to leak out, making drivers acceptable for use with audio/visual systems. Despite many advantages provided by neodymium magnets, the lack of economy due to the fact that neodymium magnets is one of the rare metals, may be the only discouraging factor.
First use of Alnico magnets.
Composed of Aluminum, Nickel and Cobalt, MPCO’s buyer JBL was the industry leader in introducing this strong permanent high power alloy in professional speaker systems.
Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss (0.15 tesla), or about 3000 times the strength of Earth’s magnetic field.
First introduced in the D130, 15-inch transducer.
