DYNAUDIO Evidence Master

Unusual is the speaker´s modular construction: the Evidence Master comprises of three individual sections. The two - technically identical - upper and lower sections house the bass drive units, while the middle section contains the midrange and treble drive units and the crossover, the latter which is further isolated within its own individual compartment. This construction offers a tremendous performance advantage, as each
section can be optimized for the differing requirements of precise bass, midrange and high frequency reproduction.

The middle section features a massive CNC-machined solid aluminum baffle which houses two special Dynaudio MSP (Magnesium Silicate Polymer) cone midrange drivers and two perfectly matched and meticulously selected Dynaudio coated soft-dome tweeters. The elegant design of the aluminum baffle is a direct result of geometric optimization for absolutely perfect sound dispersion. At the heart of the Evidence Master is the crossover. Contained within the aluminum middle section in its own sub-compartment, it is completely shielded from acoustic vibrations.

The upper and lower cabinet sections are both crafted from HDF to provide the ideal foundation for the four high performance bass drive units. These two compact cabinets house the woofers and provide a much more stable and resonance-free environment as compared to what a single, large cabinet would yield. At the same time the cabinet wall’s multi-layer sandwich construction ensures perfect energy absorption and resonance damping. Each woofer’s die-cast aluminum basket is secured to the HDF cabinet by no less than twelve screws.

The cones of the bass- and mid-range drive units are manufactured from MSP (Magnesium Silicate Polymer), a composite material developed by Dynaudio that is characterized by low mass, high rigidity and ideal internal damping properties. Ultra light-weight aluminum voice-coils with powerful magnet structures drive the speaker cones. The integration of four relatively compact woofers provides the higher dynamic range and faster transient response so typical of lighter and smaller cones – this in contrast to the ubiquitous single, large but therefore also slow woofer. The required total cone surface area necessary for deep and powerful bass response is achieved via all four Evidence woofers performing in tandem. The Evidence bass response is further enhanced by the bass-reflex ports located at the back of the speakers’ cabinets. These large diameter ports have been specifically shaped to eliminate harmful resonance.

The Dynaudio drive units are mounted from behind inside the solid aluminum baffle which itself has been CNC-machined from a single block, yielding no mountings or screw heads visible from the outside. The magnet assembly of tweeters is aerodynamically shaped and damped to fully absorb the energy dissipated from the rear of the tweeter dome. With specially coated fabric soft domes, the frequency response easily exceeds 28,000 Hz, with no distortion and without the problematic resonance and uncontrolled transient response so typical of, for instance, metal dome tweeter designs. Dynaudio tweeters are capable of handling over several thousand watts in transients without suffering any compression.
