Compact (only 5 cm frame depth), ISU165 is a high-power slim equipment (140 W max / 70 W RMS). This kit, as discreet as it is robust, promises an improvement in audio systems without causing major modifications to the passenger compartment. Let yourself be carried away by this essential place dedicated to Focal sound and performance.
SOUND POWER
Polyglass diaphragm, aluminum/magnesium tweeter... ISU165 delivers a natural, uncolored, clear and detailed sound, magnified by the ogive of the loudspeaker which guarantees optimal dispersion of the soundstage.
SLIM PROFILE
ISU165 is the result of studies carried out on the constraints associated with installation in original systems. Its extreme compactness makes it an all-purpose piece of equipment, replacing your original audio system with ease.
VARIOUS INSTALLATIONS
The removable tweeter can be installed in several ways: flush-mounted, on an inclined or flat support, or directly behind the original grille. These options allow for a variety of installation possibilities to facilitate mounting without compromising the sound experience.

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.
