The ISU 165 delivers natural, uncoloured sound with excellent clarity and detail, thanks to its Polyglass membrane and aluminium/magnesium tweeter. This 2-way component kit produces well-defined mids and high-finesse treble, while the ogive design ensures optimal soundstage dispersion. Its slim 49mm mounting depth makes it a perfect upgrade for factory audio systems without major modifications. The removable tweeter can be flush-mounted, angled, or placed behind the original grille for flexible installation. With 140W max power handling and 93dB sensitivity, it brings high-fidelity car audio performance to your daily drive.
