ICU 165 Universal Integration 6-1/2" 2-Way Coaxial Speakers 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 aluminum/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 aluminum/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.
