Scan-Speak D3004/6640-00, 1" Beryllium Dome Tweeter 

  • AirCirc Magnet System
  • Black rubber painted aluminium faceplate
  • Beryllium Diaphragm 


This tweeter features a 99% pure Beryllium dome diaphragm. The large roll surround and Beryllium dome diaphragm provide a flat frequency response to above 40KHz with outstanding off-axis dispersion and a silky-smooth sound.

ScanSpeak’s unique AirCirc Magnet System -- named for the way it optimizes air flow within the chamber –- rearranges the traditional magnet structure from a single magnet to an open magnetic circuit comprised of six separate neodymium slugs. This, in combination with the chamber, results in the elimination of the reflections and resonances that compromise the performance of traditional motors. 

The D3004 gives engineers improved control over critical midrange performance, for superb vocal rendition and excellent imaging at all listening locations.

Driver Highlights:

  • 1" Beryllium Diaphragm (99% pure Beryllium)
