The M90 is an 3” Mid-range driver offering an extraordinary performance and sound clarity.
New Glass-fibre cone, excellent internal damping together with perfectly matched moving parts gives a smooth, extended frequency response. The large, open weave fabric spider reflects very little acoustic energy to the cone, and offers excellent stiffness linearity. A stiff and stable CNC aluminum chassis keeps the critical components in perfect alignment. The pole piece is prolonged forwards and equipped with a deep drawn copper cap to ensure excellent linearity in the force factor and coil inductance. Small size combined with an excellent performance makes this driver the perfect election for any application where limited space is a critical parameter.
