The SM 9160 is a premium, large-diameter High-Tone Single Disc Horn designed for vehicles requiring a sharp, penetrating, and high-decibel warning signal. Featuring an oversized 98mm diaphragm, this single unit is engineered to provide maximum sound resonance and clarity. It is an ideal replacement for weak factory horns or can be used as a targeted "High-Tone" addition to an existing A/C or horn system.
