🔊【Value Combination】2 * speaker port tubes. (1.5’’ x 3.1’’)
🔊【Bass Effect】Because the sound pressure of the airflow vibrated by the speakers in the box pours out and overlaps with the radiated sound pressure in the front of the speakers, the speaker port tubes produce excellent bass effects.
🔊【Outstanding Feature】The speaker box bass port can amplify the volume of the bass and improve the speaker’s efficiency without increasing the power of the speaker itself.
🔊【Exquisite Workmanship】The inside of the speaker box parts are very smooth, and the one side is designed with flare for smoother airflow and better sound quality.
🔊【Multipurpose】The black port tube can be used to replace old speaker parts and make new speakers, suitable for inverted speakers, portable speakers, home speakers etc.
