From the manufacturer

Harman Kardon FIT 4SF – 100 mm (4") 1-way midrange for ultimate sound precision

The Harman Kardon FIT 4SF mid-range range (100 mm / 4") are designed to provide your car audio system with ultimate luxury sound. As a dedicated 1-way midrange speaker, it delivers exceptional clarity in mid-frequencies. In addition to uncompromising audio quality, Harman Kardon focuses on sustainability: the speakers are produced using recycled post-consumer materials (PCR). These mid-range range units combine superior sound properties with a minimal ecological footprint.

Plus One fiberglass membrane
