Graphene coating for improved micro-detail! Read Seas Graphene White Paper PDF
Magnesium cone with graphene coating for extra micro-detail + fabric dome tweeter. SEAS R&D lab recently decided to see what could be accomplished by applying their state of the art Excel Graphene technology to a coaxial drive unit. The answer can be found in their Excel C16NX001/F, and the results are amazing. Further FEA optimized motor system for higher dynamic precision, and T/S parameters more suitable for bass reflex than original C16N.
High damping magnesium is a superior material for woofer cones because of its damping properties and light weight, combined with the good sound speed which stems from the stiffness-to-weight ratio. For woofer cones, the damping is of highest priority, even if it compromises stiffness a bit, because the woofer cones have their early break-up modes inside the audible frequency range. The Graphene-coating technology used by SEAS was developed in cooperation with CIC nanoGUNE in Spain: www.nanogune.eu/ and Dr. Perez-Jimenez. 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.
As with other designs in the Excel Graphene range, the precision cast, machined, and Graphene treated magnesium cone acts as a piston through the working frequency band without showing any sign of midrange resonance. High purity Graphene, which is a nano-material with special properties, is added to the surface treatment. The SEAS Excel magnesium cone itself is known for its low moving mass and its high stiffness and damping, unrivaled in the industry, and therefore capable of transmitting even the finest details from mechanical motion into the air, resulting in the cleanest and purest sound.
The woofer has an FEA optimised magnet system with precisely fitted copper parts for excellent linearity, high powerhandling and low distortion. A titanium voice coil former with a long copper clad aluminium winding for excellent force transfer, transient sound reproduction and large linear excursion. This results in very low mechanical damping for better clarity and brings out the micro details in the music. The coaxially arranged tweeter with a precoated fabric dome is fitted with a Titanium former, has a low resonance frequency and integrates with the cone driver to form a point source for excellent sound stage imaging.
The extremely stiff and stable injection moulded metal basket designed for smooth air-flow, keeps the critical components in perfect alignment and reduce sound reflection, air flow noise and cavity resonance to a minimum.
SEAS designed and manufactured its first coaxial drivers more than 20 years ago. Early on, R&D engineer Bjørn Børja recognized the unique possibilities created by the new neodymium magnet technologies; allowing us to design a high performance tweeter in a very compact package. SEAS has continuously refined coaxial driver technology over the years, and today remains the only loudspeaker driver manufacturer to make this unique technology available to the OEM and hobbyist markets.
