Satori 7.5" MW19TX-4 TeXtreme Cone Woofer - 4 ohm
Overview
TeXtreme - Combining ultralight weight, high stiffness and controlled break up behavior
New in the premium SB Acoustic Satori line is the 4 ohm version of their premium woofer with Neodymium magnet, aerodynamic chassis and woven TeXtreme cone. TeXtreme is an advanced, super thin carbon fiber fabric that maximizes the strength-to-weight ratio.
Our new advanced carbon fiber cones are made from TeXtreme® spread tow fabric. The spread tow technology offers several advantages over regular 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).
The outstanding physical properties of this composite material has allowed us to design cone profiles that normally wouldn’t perform well with commonly used materials. When supported by a small TeXtreme ® coupler cone (attached at a critical diameter), the integrated concave cones produce a smooth frequency response throughout the midrange area with minimum excitation of break-up modes.
The high bending stiffness of the cones also ensures true piston operation at low frequencies, which guarantees a solid bass reproduction. The cones are perfectly matched with our new dedicated low damping rubber surrounds. This combination ensures excellent micro dynamics/resolution and transient reproduction without leaving any trace of the unwanted edge resonance – midrange distortion is at a minimum.
This unit features smooth frequency response and low inductance allowing for minimal effort in network design.
Designed and engineered in Denmark.
