Cosmetically attractive driver with high-tech graphene coating, titanium VC former and phase plug. Great for bookshelf or MTM, smooth midrange up to 1Khz or so. Can tune very deep for small driver.

The new W12CY004 (E0070-08) is a state-of-the-art mini woofer and midrange speaker in our Excel-Graphene series, upgraded with a magnet system with a new combination of copper rings and caps, optimised for lower distortion through better linearity and symmetry, and a new voice coil with titanium former. It is a successor to E0021-08S from SEAS.High purity Graphene, which is a nano-material with special properties, is added to the surface treatment. Please see our white paper for details. (Chinese version: CN). Low mechanical and electromagnetic damping ensure high quality reproduction of even the finest micro details in music. At the same time, the high-performance titanium voice coil former and its connection to the cone has very high power handling, suitable for modern amplifiers (e.g. Class-D). The driver has exceptionally high dynamic capability, which the light and stiff and well-damped magnesium cone converts into clean and undistorted sound. Therefore, the driver is designed with dynamic precision in mind for truthful reproduction of high-resolution sound.

The precision cast, machined and Graphene treated magnesium cone acts as a piston through the working frequency band without showing any sign of midrange resonances. The FEA optimized motor-design boasting both a copper ring and cap represents the state-of-the-art regarding linearity and low distortion. Low mechanical and electromagnetic damping ensure high quality reproduction of even the finest micro details in music. At the same time, the high-performance titanium voice coil former and its connection to the cone has very high power-handling.

The smooth frequency response and ample linearity make it very suitable both as a dedicated midrange and as a woofer in a small compact speaker. The extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
