What is a bass reflex tube for?
Bass reflexes are to be placed in a speaker enclosure to allow air to pass in and out to aid in regulating the pressure generated by the vibration of the diaphragm. This is referenced as a reflex enclosure.

Suitable whether you’re making your own speaker cabinet or modifying an existing cabinet. A larger bass reflex tube allows greater airflow in a reflex design cabinet, will be larger to be in proportion to the speaker used among other factors.
