Neo loudspeakers
are the future for many audio applications. Neodymium magnets are more powerful and lighter weight than conventional
materials. Often Neo speakers are more efficient and have wider bandwidth than speakers made from other magnetic
materials. (Alnico, Ferrite, Samarium Colbalt) Neo often gives the engineer more options when designing a transducer.
It's easier to make speakers sound better when you start with the highest technology magnetic material available. In the
majority of cases speakers made with Neo are "video shielded". This essentially means, no stray flux to interfere
with CRTs, computers and magnetically sensitive storage media.
Nd2Fe14B is the strongest permanent magnet available today. It's more than 10 times more powerful than typical
loudspeaker magnets. All though it is a rare earth element development into the form we use today began in 1982 with
the car industry leading the way.(alternators, starters) In the sound business Neodymium is primarily used in Guitar
Pickups, Headphones Loudspeakers and Microphones. In the past neodymium could demagnetize inside a woofer when
a lot of power input generated enough heat. That problem is now in the past. High temperature Neo is now common
and readily available. Some grades of Neo can tolerate temperatures as high as 750 degree F (400 C) without any ill
effects.
