Premium 5" woofer with Neodymium magnet, aerodynamic chassis and woven TeXtreme cone. TeXtreme is an advanced, super-thin carbon fibre fabric that maximizes the strength-to-weight ratio. The spread tow technology offers several advantages over regular Spread tow fabrics, such as very low crimp, lower weight and improved cosmetics (cones are very flat and smooth). The laminated thin-ply TeXtreme® material has an excellent stiffness-to-weight ratio (though surpassed by beryllium, it is also significantly less expensive). Available in 4-ohms and 8-ohms models.
