Sub120_vHE is the top of the art loudspeaker for low frequency reproduction in compact high-end HiFi.

 

It integrates several innovation such as the dynamiK spider which keep constant Fs[Hz] over the full excursion, and the advanced motor structure, providing very linear force factor Bl(X) and inductance Le(X].

 

The motor structure is built with dual high grade Neodymium magnets, and dual Aluminum rings to avoid inductance modulation and offer very low distortion performances.

 

The membrane is made of Aluminum cone and proprietary CGF dust cap, which extend the frequency response over 3500Hz to built 2 ways systems.
