Lom165_vPA-H is a professional Mid-woofer designed to reproduce 60 - 2000Hz (-3dB) with high dynamic range and very low distortion.

Suspensions use dynamiK spider and low lost Kompliance surround to reduce significantly the non-linearity.

The motor structure, engineered with FEA, is built with Neodymium and ferrite magnets to produce intense and focus magnetic field.
