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.In conjunction with the advanced metal baffle construction, an extremely stiff and rigid unit is created, further ennobled by the finely polished surface of a beautifully finished real wood veneer. The innovative base plinth, derived from the Dynaudio Confidence range, serves as a stylish yet solid stand for the speakers.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.With the Original Box and Manual.Send me your zip code and I will quote you the shipping charges.
