Product Overview
The Focal Utopia 6WM is a high-performance 6.5-inch woofer designed for demanding car audio enthusiasts. As part of the prestigious Utopia line, this speaker driver embodies Focal's commitment to innovation, precision engineering, and pure sound reproduction. Built with sophisticated materials and advanced manufacturing processes, the 6WM is engineered to deliver exceptional harmonic richness and faithful audio performance in automotive environments.
Technical Specifications
The 6WM woofer is built to handle significant power while maintaining clarity. It features a nominal power handling of 100W and a maximum power handling of 200W. The driver utilizes a high-quality W-cone and a durable Butyl surround, ensuring longevity and consistent performance. With a nominal impedance of 4 Ohms and a sensitivity of 91.5dB (2.83V/1m), it is designed for integration into high-end audio systems.
Mechanical Design and Performance
The mechanical construction of the 6WM includes an 80mm voice coil diameter wound on a glass fiber former, utilizing CCAW wire for optimal efficiency. The magnet assembly measures 75x4mm, contributing to a net weight of 1,050g. The design is optimized for precise control, as evidenced by the detailed mechanical drawings provided in the documentation, which specify mounting dimensions in millimeters to assist with professional installation.
Performance Parameters
The 6WM exhibits a frequency response tailored for high-fidelity sound, with a resonant frequency (Fs) of 70Hz. Key Thiele/Small parameters include an Rdc of 2.7 Ohms, an Mms of 14.5g, and a Qts of 0.79. These parameters indicate a driver capable of controlled, accurate bass and mid-bass reproduction. The excursion capability (Xmax) of 5.5mm allows for significant output without compromising sound quality. Users should refer to the provided frequency response charts to understand the driver's behavior across the spectrum, noting the performance at both 0 and 30-degree off-axis angles.
Quality and Heritage
Focal products are designed and manufactured in France, adhering to strict quality standards. The Utopia series represents the pinnacle of the brand's expertise, combining aesthetic elegance with technical excellence. By mastering every stage of the manufacturing process, Focal ensures that each 6WM woofer meets the rigorous demands of audiophiles seeking the ultimate listening experience in their vehicles.
