Ci130.2QR/QS Architectural Specifications

The Ci Series Ci130.2QS and Ci130.2QR comprise a Uni-Q® coincident mounted 19mm aluminium dome tweeter with a 130mm white polypropylene bass/mid unit.

Performance should meet or exceed the following criteria: frequency response 1 metre on-axis with swept sinewave shall be 50Hz to 40kHz QS, 100Hz to 40kHz QR, sensitivity shall be at least 86dB for 2.83V@1m. The impedance and maximum power shall be 50W at 8 ohms.

Applications

The Ci Series Ci130.2QS and Ci130.2QR 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.
