Architectural specifications:
The Ci Series Ci400 and Ci400T comprise
a 19mm aluminium dome tweeter and
100mm white polypropylene bass/mid unit
with double neo compound magnet
system. Performance should meet or
exceed the following criteria: frequency
response 1 metre on-axis with swept sinewave shall be 80Hz to 27 kHz,
sensitivity shall be at least 88dB for
2.83V@1m. The impedance and maximum
power shall be 50W at 4 ohms. The Ci
Series Ci400 and Ci400T is best suited
where high quality music and speech
reinforcement applications require hi-fi
performance such as: · Multi Room systems.
· Home Theatre systems.
· Lounges, Bars, Boutiques.
· Boardrooms & Offices.
· Airports, Convention Centres, Hotels.
· Live Theatre/Concert Hall fill-in.
· Houses of Worship.
· Sports Arenas.
