Tweeters for usage in home HIFI boxes have traditionally been part of the LPG production program. In this production line classical magnetic drives are employed. Mounting plates of synthetic, aluminum or diecast materials can be combined with variable moving parts of aluminum, fabric or magnesium.
LPG was one of the first OEM manufacturers that used neodymium drives. This technology allows especially in the automotive field a very small and light construction of the tweeters. Also here it is possible to use very flexible fabric-, aluminum-, titan- and supronyl-domes.
