Wib120_vHE
Wib120_vHE is a modern wide band, allying low frequency extension and linear frequency response up to 22kHz.
The cone (exponential profile) is made of mixed cellulose and glass fiber, with specific damping applied on the back of the membrane to minimize sound coloration.
The motor structure is built with very low carbon steel, high grade magnets (Ferrite and Neodymium).
Thanks to the stepped voice coil, the Wib120_vHE has low moving mass and wider force factor [Bl(X)] than most of its competitors.
