The speaker cabinet port tube used to improve the bass response of many types of speakers.
It is commonly used in the inverted phase speaker, mainly to overwhelm the air flow sound of the speaker in the box and overlap the sound pressure radiated in front of the speaker to produce a bass effect.
These port tubes guarantee a reliable, convenient installation, while at the same time providing a finished, "pro" look to your bass reflex speaker building project.
