The Ventus-12 is a powerful, compact and easy to transport single 12" subwoofer.

The long excursion 12" chassis has a high power handling 4" voice coil. A low moving mass ensures an extremely precise and at the same time deep, dry bass reproduction. The large reflex port and high mechanical excursion give the bass excellent dynamics and effectiveness. The Ventus-12 provides a performance that one would not expect from a subwoofer of this compact size.

A removable wheel board can be attached to the front for easy transport. A protective cover protects the surface and ensures value retention.

The two large handles can be grasped from all sides, are in the centre of gravity and ensure comfortable handling.

Rubber feet and stacking troughs guarantee a secure stand without slipping. An M20 flange for distance rods is integrated.
