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.

FEATURES

  • Cast aluminum frame promotes motor cooling
  • Sculpted design improves airflow and reduces reflections
  • High-strength compact neodymium magnet system
  • Proprietary coated natural wood fiber cone with half-roll rubber surround
  • Long-throw 1-1/4" voice coil on titanium former
  • Copper pole piece cap for extended HF response
  • 4 Ohm nominal impedance
