To minimize mechanical vibrations the baskets are made of casted aluminum for a maximum of rigidity.
The rigidity of the aluminium aluminum combined with the damping of a cellulose layer - thanks to aluminium aluminum sandwich technology, the audio reproduction achieved by ELAC bass drivers is very precise.
In a special glueing procedure, an aluminium foil of 0.2 mm is joint to a pulp fibre cone to form a sandwich membrane.
The result: reduced partial oscillations, no distortions and an optimized large signal behaviour.
In combination with the aluminum-coloured tweeters, the aluminum sandwich woofers also make innovative technology a visual experience.
Thanks to their coaxial design, not only do the bass drivers and tweeters never miss a beat, with their compact design they also complement each other perfectly. Sometimes the best things come in small packages.Early in the R&D process of the 301.2 coaxial driver the idea was to improve the sound performance of a bass driver based on a predefined enclosure size. The solution came quickly and led to the present oval shape. More difficult was the design and integration of the tweeter. The goal was being compact without compromising sound quality. After initial listening tests a fabric dome version was out of question. In search of the ideal position of the tweeter, multiple listening sessions proved that a concentric orientation of both drivers did not deliver acceptable results. This finally led to the asymmetric coaxial array. After further listening tests and multiple measurements it was obvious that a premium and well-balanced solution in this particular case could only be achieved far from what the textbooks would suggest.
Even at higher volumes, the fabric dome tweeter always provides a smooth audio experience.
Transparent sound is reproduced by this 25 mm tweeter consisting of a coated silk dome resulting in a smooth roll off at frequencies above 20,000 Hz without noticeable resonances. A special wave-guide together with the protection grille results its wide dispersion characteristics.
Its extraordinary power handling capacity is resulting from two design features: the compact high efficiency neodymium magnetic system with cooling fins and the aluminium voice coil cooled by ferro-fluid.
Additionally, the magnetic system is shielded.
Due to the new faceplate (back high gloss) only the tweeter grille and woofer diaphragm are visible, the kick of the new 60.2 Series.
Watch television without having distorted color - thanks to magnetic shielding these ELAC speakers can be installed right next to CRT screens or devices with hard drives sensitive to magnets.Thanks to the magnetic shielding, these speakers can also be set up in proximity to cathode ray tube TVs or devices with integrated hard disks or attached to them without creating interference.
