The Contour Cabinet is strengthened by cross braces in specific areas to achieve a solid, vibration-free construction. Internally, the MDF walls are damped with an extremely dense material that absorbs even the most microscopic resonance.
The crossover is mounted on a smaller block, between the plinth and the cabinet, away from unwanted vibrations and resonance, while using the shortest possible path-lengths to the gold plated WBT terminals. The sensitive components are thus isolated from any potential performance compromising factors. In the S 3.4, the new Esotec tweeter is used; it features a double magnet system that ensures extremely high power handling and precise control of movement of the dome.
