Bass Reflex speakers are designed so that sound waves emitted from the back of the diaphragm are routed through ports or vents (collectively, ports) in the cabinet to enhance bass quality.

These ports, depending on the needs of use, can design one or more ports , mounted on the front or back of the speaker cabinet, the cross-section and length of the ports can also greatly improve the efficiency of use. compared to similarly sized closed-cabinet loudspeakers.
