Easy Installation: By simply inserting a sponge of the correct diameter into the speaker's port tube, you can instantly improve sound quality and easily upgrade your sound setup. Wide compatibility: Highly versatile and suitable for a wide range of devices, including modified speakers, home speakers, car speakers, portable speakers, PA DJ subwoofers, and more. Reducing standing waves: This plays a crucial role in minimizing standing waves generated by speaker vibrations. By effectively damping these waves, the sponge reduces unwanted wind noise and jarring sounds, contributing to a more enjoyable listening experience. Select the appropriate size. Choose the required sponge plug diameter according to the inner diameter of the speaker port tube. The sponge diameter should be slightly larger than 5mm than the inner diameter of the speaker port tube. A larger sponge will allow it to fit securely into the speaker port tube. Enhanced bass reflection: The sponge provides speakers with enhanced bass reflection capabilities, improving the low-frequency response across various speaker types.
