The Vifa NE product line has leading-edge transducer technology packaged in a
cutting edge, stylistic design. The tweeters in this product line finite element
analysis designed Neodymium-Iron-Boron magnet (NdFeB) motors, with copper caps
for extended frequency response and reduced distortion. The aluminium rear
chambers offer extended low frequency performance, while doubling as heat
sinking. The butterfly supporting the tweeter diaphragm is made of a high
temperature plastic, consistent with the product's high temperature performance
rating, and features supporting terminals. The dome material in this design is
titanium, and the design has been optimized for sound quality and clarity.
Rounding out the design is an aluminium face plate and plastic grille, which
offers protection for the tweeter diaphragm.
