Focal ICU 100

4" Coaxial Speaker System

Easy To Fit, Perfect Integration
The ICU Universal 2-way coaxial speaker kit improves on your original-fit speaker installation. Its compact size, achieved by reducing the housing depth, and its snap-off fixings make this kit easy to fit. The new generation Universal comes with innovations and new features, including a new inverted aluminium/magnesium tweeter for even more detailed treble reproduction. A new chassis has also been designed for optimal integration and a more elegant design. All this is with just one objective: to offer easy-fit products that maintain excellent sound. On this coaxial model, the aluminium/magnesium tweeter has a 2-position +3 dB adjuster (Flat/High) for treble boost. This adjustment comes into its own when the speaker is placed low in the door. Shallow fitting: 49 mm.

Natural, Uncolored Sound
The Integration range is synonymous not only with ease of installation but also and most especially, with sound quality. At Focal we pride ourselves in supplying equipment of impeccable quality: for example, a polyglass membrane for natural, uncoloured sound and an inverted dome aluminium/magnesium tweeter for clear, detailed reproduction.

Reliability A Top Priority
The Focal spirit also encompasses the reliability of our ever evolving technological equipment. Butyl suspension ensures that your speakers will stand the test of time. You will be able to enjoy the Focal sound for a long time, thanks to our high quality design: manufacturing processes and the choice of materials are always high priorities for our engineers, guaranteeing a result that exceeds your expectations.
