Description

For the two-way system of the TCD 410 R we have developed a 17 cm bass / mid-range driver which offers superb dynamic qualities in the bass range as well as operating effectively in the mid-range, with a completely unfettered, uncoloured and open character. This unit also features our GREYCONE® cone. This consists of airdried wood fibres and graphite particles, producing an extremely stable, highly damped, amorphous material which eliminates any systematic propagation of structure borne sound in the cone.  To prevent any form of resonance and break-up in the extremely critical mid-range area, the cone incorporates carefully defined slots which are sealed with a special adhesive; this not only stiffens the cone, but also prevents all partial vibration. An optimised phase plug made of machined aluminium ensures homogeneous radiation characteristics up to 4000 Hz and above. The low-profile surround provides good damping, guarantees accurate excursion characteristics and also perfect roll-off and transition qualities in the mid-range / treble-range. The huge magnet forms a perfect unit with the rigid die-cast basket. This unique driver endows the entire vocal range with an incredibly musical and pleasant character.  Naturally the Waveguide dome tweeter is employed for the high frequency range. These two drivers harmonise together perfectly, creating tremendous detail fidelity and imaging accuracy. Massive bi-amping terminals, an extremely low-loss cross-over unit with a new form of low-saturation, low-distortion coils, and an accurately tuned bass reflex system are important constituents of this surprisingly powerful small loudspeaker.
