Specification: Item Type: Speaker Parts Material: Rubber Edge + Metal Plate Length: Approx. 65mm / 2.56in Width: Approx. 45mm / 1.77in Features: 1It has a great effect on the bass and can increase the potential of the bass. 2It is suitable for use in a closed cabinet to enhance the bass performance of the speaker. 3It can be used directly on the box to open a hole and put it on (provided the phase hole must be canceled) 4The low-frequency dive depth is equivalent to the reverse type, but the speed is obviously faster than the backward type, which has the advantage of a certain closed box. At the same time, it completely eliminates the disadvantage of the inverted structure, that is, the wind brought by the inverted nozzle noise. 5For those who like to dive deep, but have higher requirements for bass speed, it is better to use a radiation basin to make a subwoofer.
