TWEETER
D3404/552000
With the Ellipticor family a long tradition of circular motor structures and their inherent breakup behavior 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 LIVE sound which makes D3404/552000 one of the very best tweeters on the market!
KEY FEATURES:
- Elliptic voice coil
- Low mechanical losses
- High sensitivity (SPL)
- Aircirc optimized magnetsystem
- Unusually low distortion
- Flexible optics with replaceble decor ring
