[. . . ] The K2 S9800SE is designed to satisfy even the most demanding audiophiles and music lovers, and conveys all the power and subtlety of music and movie soundtracks with astonishing realism and emotional impact. [. . . ] Aquaplas applied to the rear periphery of the cone helps to eliminate distortion at high power levels. A Symmetrical Field Geometry (SFG) circuit creates vertical symmetry and generates a constant magnetic-flux density across the width and length of the voice-coil gap. TM The 75mm (3") beryllium (435Be) high-frequency compression driver features an Aquaplas-coated diaphragm and 25mm-throat Bi-Radial horn. ® The 25mm (1") beryllium (045Be) super-tweeter compression driver is mounted in a 12. 8mm- (0. 5"-) throat Bi-Radial horn. The K2 S9800SE crossover can be bypassed for active bi-amplification via an external crossover. The network is carefully tuned for changes in the use of high-quality capacitors. The newly adopted high-quality "fast capacitor" reduces distortion further and results in even more transparency and a richer soundstage. TM Three-step bass adjustment, theree-step treble adjustment and normal/bi-amp switching are possible with control switches on the network panel. Large, extruded stainless steel-feet with selectable round and spike tips.
