The Ventus-18 is a powerful, compact and easy to transport single 18" subwoofer.

The long excursion 18" 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.

For optimum packing density in mobile applications, the dimensions of the subwoofer take the truck loading gauge into account.

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

In order to save working time during assembly and dismantling, there is also a quad roll dolly with cover for 4 stacked subwoofers for touring use. The dolly also keeps the truck loading gauge.

4 large handles ensure comfortable handling. The side handles at the rear end of the subwoofer make it easy to lay down and stand upright with minimal effort by lever action. When loading with only one person, the rear handles are very helpful.

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