Scan-Speak - Ellipticor Dome Tweeter - D3404/552000

Description

New innovative engineering concept of an elliptical voice coil distributes any resonant node patterns and breakup energies evenly across the whole frequency spectrum thus producing less distortion. In combination with the powerful SD AirCirc magnet system with high sensitivity, very low distortion, and has an extremely fast response to transients. Above all a TRUE TO LIVE sound which makes this one of the very best tweeters on the market today. One of the design goals for a new driver concept at Scan-Speak was to minimize cone modes, so it was suggested to use an elliptical voice coil ! This radical idea has some interesting engineering science behind it. Driving a diaphragm symmetrically, with a circular voice coil, you get a finite number of Eigen frequencies with an energy contribution combining at certain points producing measurable colouration modes and resonances contributing to distortion and a driver introducing its own unique signature tone. The elliptical voice coil idea is to drive the diaphragm asymmetrically, so what you get is an “infinite” number of Eigen frequencies. These multiple “natural resonances” are more widely distributed producing random modes and as a result, less resonant energy contribution totally overall. This achieves lower distortion with less colouration node energy and thus improving desired audible results by reducing the drivers 2nd order harmonics and excellent 3rd order harmonics improvement. In combination with the powerful SD AirCirc magnet system the Ellipticor Series has high sensitivity, very low distortion, and has an extremely fast response to transients. Above all a True-To-Life sound which makes Ellipticor one of the very best drivers ever available.
