What is a Speaker Box for?
Everyone understands that the box is an indispensable part for the proper operation of the low-frequency speaker, which is designed to work in a certain volume, without it, the subwoofer speaker will simply chase the air, while the efficiency will decrease several tens of times.
Without a box, due to the lack of the necessary damper, the speaker is very easy to pull out of the stroke, this is when the coil starts to come out of the magnetic gap, it is at this point that any slight distortion of the diffuser can lead to a coil's impact on the core (cylindrical magnetic core in the center of the coil), which leads to the detachment of the winding from the coil frame.
Of course there are exceptions, for example, as Free Air subwoofers, which are designed to work in an open volume, but the efficiency of these subwoofers is very small, it is recommended to install them only as a last resort.
