Couldn't load pickup availability
The Universal ICU570 2-way coaxial speaker kit 5 x 7" advantageously replaces the original equipment of your vehicle. Its high compactness, obtained by reducing the installation depth, and its breakable fixings facilitate the assembly of this kit It promises a quality audio solution meeting all installation needs and offering Focal in-car listening.
PERFORMANCE AND DESIGN
The tweeter delivers clear, detailed sound, while the woofer's Polyglass cone reveals perfectly defined midrange. The loudspeakers have been designed with a single objective in mind: to offer you products that perform well in all circumstances.
BETTER SOUNDSTAGE
The horn starter on the kit guarantees efficient soundstage and coupling to the ambient air.

TECHNOLOGIES
TWEETER IN AL/MG
Treble finesse
Membrane shape and materials are essential. For the finest treble, our engineers have patented the inverted dome tweeter, a Focal signature. The inverted dome shape offers the advantage of low directionality and a small-diameter, lightweight coil for better acceleration. As for the materials used, they combine the key points of a good loudspeaker: aluminum increases dome rigidity and reduces distortion, while the addition of magnesium provides excellent damping. The surround that connects the dome to its support uses Poron, a shape-memory material. This surround is derived from the famous Utopia Beryllium tweeter, and reduces distortion by a factor of three between 2000 Hz and 3000 Hz, where the ear is most sensitive.
POLYGLASS MEMBRANE
Well-defined mids
The diaphragm, the key component of a loudspeaker, is at the heart of our acoustic engineers' research. Polyglass technology, exclusive to Focal, consists of applying fine glass microbeads to a cellulose pulp cone. This process reconciles the excellent damping of paper with the rigidity of glass. The stiffness index is almost 10 times that of polypropylene. Adjusting the mass-rigidity-damping ratio results in a remarkably linear frequency response curve, right from the membrane design stage. This innovation also significantly increases definition in the midrange register.
