Locate the port material which you are going to use. Trace the pattern
of the appropriate hole needed for the port, then cut the hole out. When
installing the port, make sure you have a distance of at least the diameter
of the port from the end of the port to the wall inside the box. To best
seal off any air leaks use silicone around the inside edge. Also, bevel
the inside edge of both ends of the port to cut down on port noise.
找到您要使用的端口资料。 追踪模式
端口所需的适当的孔，然后把孔切掉。 什么时候
安装端口，确保至少有一个直径的距离
的港口从港口端到箱内的墙壁。 为了最好
