Information

The GTi250S downfire subbox is built with a 10-inch passive radiator and delivers rich bass without taking up much space in the trunk. Thanks to the resonating passive radiator, long bass reflex channels and large internal volumes can be dispensed with without having to forego powerful bass. The GTi downfire subboxes are therefore very flat and can be installed almost lying flat in the trunk. They act as a double bottom and even purchases can be placed on them.
