Radiator-made subwoofer has the following advantages compared to traditional inverted subwoofers.
The diving depth is equal to the depth of the reverse direction, but the feeling of speed is obviously faster than the rear sense.
It has the advantage of a certain closed box, while at the same time completely eliminating the disadvantage of inverted structures, the noise of the inverted nozzle.
