Harman Kardon FIT4F coaxial speaker system 100mm 30–240W 70Hz–40kHz 90dB 4ohm

Harman Kardon FIT4F — Coaxial Speaker System

In the automotive environment, where sound quality is often limited by space constraints and acoustic conditions, the Harman Kardon FIT4F delivers a clear and dynamic listening experience. This 4" (100 mm) coaxial speaker system offers 30 W RMS power handling with a peak output of up to 240 W, ensuring ample power to fully realize the music's potential. With a frequency response of 70 Hz-40 kHz and a sensitivity of 90 dB at 2.83 V, it delivers precise reproduction ranging from deep bass to delicate high notes. Thanks to unique technologies such as the patented Plus One cone and Uni-Pivot design, the FIT4F delivers an exceptional audio experience.

Superior acoustic technologies for every detail

The Harman Kardon FIT4F speaker utilizes a patented fiberglass Plus One cone, which offers a larger cone surface area at a lower weight. This results in higher sensitivity and ensures more precise, impactful bass compared to other speakers of the same size. The edge-driven textile dome tweeter enables high-frequency reproduction up to 40 kHz, ideal for capturing subtle details without harshness or distortion.

Flexible installation and sound optimization

Thanks to the Uni-Pivot design, the tweeter can be rotated up to 270° after installation, allowing for precise sound aiming based on listener preference. Additionally, the tweeter output level can be adjusted to 0 dB or -3 dB, ensuring optimal sound linearity across various mounting conditions. A slim inline crossover simplifies installation and sound customization.

Expandability and eco-friendly manufacturing

The FIT4F is made from recycled materials, supporting sustainable manufacturing. For audio enthusiasts, it offers the option to upgrade to a three-way system by adding an optional 3.5" midrange driver via a switch on the crossover. This delivers even broader frequency coverage and improved separation of individual sound ranges.
