Equipped with Tannoy’s unique and exclusive point source ICT™ 165 mm (6.50”) drive unit, the AMS 6ICT LS delivers an acoustic performance of outstanding clarity, definition and detail. The point source configuration of the Tannoy ICT™ driver’s mid-bass and tweeter sections ensures a wide and controlled dispersion for optimum coverage; this while avoiding the massive loss of energy in the vertical plane, at the crossover frequency, inherent in two-way discrete designs. The ICT (Inductive Coupling Technology) drive unit also addresses the two most common component failures experienced in background music and sound reinforcement systems, the tweeter and the crossover reliability. The use of a wireless electromagnetic tweeter means that no crossover is required in the design; this therefore ensures that an ICT unit is exceptionally reliable and therefore ideal for applications where constant heavy usage is the norm. This aluminium high frequency dome has a deep drawn skirt that sits on the inside of the low frequency voice coil in the same magnetic gap. The skirt is like a single shorted turn that is induced with high frequency information generated by the low frequency voice coil, which is fed a full bandwidth signal. The mineral loaded polypropylene cone material and nitrile rubber surround further enhance durability and long-term reliability. The AMS 6ICT LS is UL-1480, category UUMW when installed with a junction box (on-wall or in-wall). For use with non-DC supervised systems.
