Lom135_vPA-S is a high quality low-midrange for demanding compact professional application.
 

It provides very dynamic and accurate sounding from 150Hz to 2500Hz.
The motor structure is based on large ferrite magnet (Ø110mm).

 

It uses advanced pole pieces geometry and cooper ring to keep very low THD on useful bandwidth.
The membrane is made of pressed paper and carbon fiber dust cap to provide more linear frequency response.
