rev 2_0Revision:
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 aluminum, 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.
