Treble Unit

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 preventing strange color distortions in a TV screen. |
Midrange Unit
MT 140 AS midrange used in FS 68.2
The midrange cone is designed in the ELAC proprietary aluminium-sandwich technique which avoids noticeable resonances in the diaphragm.The "Full-Roll" fabric surrounding expands the transmission range up to high frequencies to facilitate the crossover to the tweeter.
The spider is vented at both sides resulting in a symmetric membrane displacement which reduces distortions at low frequencies.
The magnetic system is shielded avoiding picture distortions in a CRT TV set.
Bass Unit
TT 175 AS midbass used in BS 63.2 and FS 68.2.
The design of the woofers of the 60 series are also based on the aluminium-sandwich technique. The wide rubber surrounding and the aerodynamic optimised - providing best air-flow - frame together with the spider being vented at both sides result in an extra large maximum membrane excursion.
The 31mm diameter voice coil and the powerful magnetic system increase the force factor - more efficiency - and by this the load limit is increased and consequently the deficiency rate decreased.
