Harman/Kardon FIT4SF

The Harman/Kardon FIT4SF mid-range car speakers are designed for component installations in car audio systems. The patented Plus One fibreglass cone uses a larger surface area and lower weight, which contributes to higher sensitivity and better performance. The speakers handle a continuous power of 45W RMS and are made from post-consumer recycled materials, reducing their environmental impact.

Patented Plus One cone

The speakers use the patented Plus One cone technology. Compared to conventional speakers of the same size, the fibreglass cone has a lower weight and a larger overall surface area. This achieves higher input sensitivity and provides better performance in the transmitted frequency band. The result is a more accurate and detailed reproduction of the mid-tones, which are crucial for the clarity of vocals and instruments.

Reliable performance and compatibility

The speakers are designed to operate even at higher volumes. This is evidenced by the continuous power of 45W RMS and a peak power of up to 360W. The nominal impedance of 4 Ohms ensures compatibility with standard car amplifiers and head units. A sensitivity of 90dB at 2.83V means the speakers efficiently convert amplifier power into sound pressure, so they play loudly and clearly even with less powerful systems.
