Sub180_vMS is a long linear excursion transducer, to be used in active compact subwoofer or 3 ways system.

We recommend to use this driver to cover the bandwidth 30 – 700Hz (-3dB).

It has been engineered to provide very accurate cone movements, with +/-11mm linear excursion.

The powerful motor structure is based on advanced pole piece geometry which focus 1.3T in the gap, keeping smooth inductance.

The suspensions use dynamiK and pumaX spiders, mounted with specific vented spacer and low lost rubber surround to avoid any mechanical damping, which could slow down the cone movements.
