Description
~38 mm Dome Tweeter, 4 ohm, Neo, AirCirc
With the Ellipticor family a long tradition of circular motor structures and their inherent breakup behaviour has been broken since one of its key features is an elliptical voice coil and magnet gap. In combination with the powerful SD AirCirc magnet system the D3404 has high sensitivity, very low distortion, and has an extremely fast response to transients. Above all a TRUE TO LIFE sound which makes D3404/552000 one of the very best tweeters on the market!
Features
- Elliptic voice coil
- AirCirc optimised magnet system
- Low mechanical losses
- Exceptionally low distortion
- High sensitivity (SPL)
- Flexible optics with replaceable decor ring
