From the manufacturer

Harman Kardon FIT 4F – Compact 100 mm (4") coaxial speakers for luxurious premium sound

The Harman Kardon FIT 4F coaxial speakers bring High-Resolution sound directly to the original flush-mounted openings of your vehicle. Developed for invisible factory integration, this extremely compact model is deliberately delivered without a protective grille. In addition to excellent audio quality, Harman Kardon attaches great importance to sustainability: the speakers are made from recycled post-consumer materials (PCR) to perfectly combine premium sound and environmental awareness.

Plus One fiberglass membrane

The extremely light and rigid fiberglass membranes use the patented Plus One technology. It offers a larger overall surface area than conventional speakers of the same size, leading to higher sensitivity and a more powerful, dynamic bass response with excellent musical character.

Compact & invisible integrated

As a 4-inch coaxial system, the FIT 4F combines the woofer and tweeter into a single, extremely compact housing. Because the system comes without a surface grate, it fits seamlessly behind your car's original door or dashboard panels – for a perfect audio upgrade that you hear in all its glory but don't see.

Hi-res textile domes (40 kHz)

The edge-driven textile dome design ensures flawless and smooth reproduction of the treble up to 40 kHz. This allows you to enjoy detailed, High-Resolution sound that, thanks to an extra-large voice coil, even at high volumes, always remains distortion-free and absolutely free of unpleasant hardness.
