Respectand conceptul sunetului clar, FS 68 castiga imediat un loc in inima ascultatorului. Iubitorul de muzica este liber sa decida daca acest sunet echilibrat si neutru, cu note puternice si precise, cu reproducere convingatoare a detaliilor, se datoreaza noului difuzor de medii sau "doar" acordarii exceptionale a componentelor.

FS 68 poate deasemenea sa zguduie casa si este potrivita sa umple camerele mai mari.

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 midrange used in FS 68 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 midbass used in BS 63 and FS 68. 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.
