Wom135_vPA-S has been engineered to reach low crossover point with subwoofer (around 60Hz) in very dynamic and accurate sounding systems.

It is built with large high grade Ferrite magnet (Ø110mm), advanced pole pieces geometry and cooper ring to get high force factor and minimum inductance.

The membrane ally pressed and treated paper with carbon fiber dust cap to provide more linear frequency response until 3KHz, and minimum off-axe deviation.
