BEWITH C-50 IIIF Tweeter

Product Description:
The BEWITH C-50 IIIF is a high-end, 5 cm (approx. 2-inch) car audio tweeter that is part of the final, enhanced generation of the company’s flagship “Confidence” series of speakers. Its primary distinguishing feature is its use of BEWITH’s unique PPC (Polar Pattern Control) eccentric cone technology, which aims to achieve superior sound coherence and controlled directivity optimized for the challenging in-car environment.

Product Features:

• Eccentric Cone Design: Unlike conventional circular speakers, the C-50 IIIF uses an “eccentric cone” where the voice coil and drive points are offset from the central axis. This design helps disperse diaphragm vibrations (resonance) more effectively, resulting in a flat and smooth frequency response with fewer peaks and valleys.
• Wide Frequency Range and Low Crossover Point: The eccentric cone technology allows the tweeter to operate effectively over an expanded frequency range (specified as 390 Hz – 28 kHz for the C-50III model). This allows for an exceptionally low recommended crossover point of around 800 Hz (compared to a typical 3-5 kHz), which places phase-sensitive transitions below the most acute range of human hearing, ensuring a seamless and natural sound quality.
• Tonal Coherence: The Confidence IIIF series uses the same structure, materials (mica polymer diaphragm, high-rigidity aluminum die-cast frame), and magnetic circuits across all its speaker sizes (tweeter, mid-woofer, and sub-woofer). This ensures consistent tone quality and a cohesive sound signature throughout the entire frequency spectrum.
• Directionality Control: The unique directional properties of the eccentric cone can be fine-tuned by rotating the unit during installation. This allows installers to precisely control sound reflection off surfaces like windows, optimizing the acoustic field and imaging within the vehicle without relying heavily on digital sound processing.
• High-Quality Materials: It features a mica polymer diaphragm, neodymium magnet, and an aluminum die-cast frame, contributing to its high-fidelity sound reproduction and durability.
