ISU130 is the result of studies carried out on the constraints linked to assembly in original installations. Slim, powerful and “all-purpose”, this kit allows improvement of audio systems without causing major technical modifications within the passenger compartment. With products from the Universal line, enjoy the quality of Focal sound in the car!
ENVELOPING SOUND
Polyglass diaphragm for the loudspeakers, aluminum/magnesium tweeter: the sound delivered is natural, uncolored, clear and detailed. In addition, the tweeter's horn cone ensures better positioning of the soundstage, for even greater listening pleasure.
EASY ASSEMBLY
The kit's compact size, achieved by reducing the mounting depth (48.9 mm), and integrated crossovers make it easy to install and connect to your original car radio. Breakaway lugs, a removable tweeter and a tilted tweeter mounting make installation in a variety of locations even easier.
OPTIMIZED TREBLE
The tweeter is equipped with a two-position Flat/High level control to calibrate the treble as required, but also to optimize the rendering according to the tweeter's position in the passenger compartment.

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.
