100mm (4-inch) Speaker Box Port - Black

Designed specifically for compact to medium-sized speaker cabinets, this 100mm speaker box port optimises low-frequency performance by tuning internal air pressure. The flared outer rim helps to reduce audible air turbulence, ensuring a cleaner bass response even at higher volumes. It features a built-in protective grille that prevents foreign objects from entering the cabinet and damaging sensitive internal components.

Product Features:

• Improved Bass Response: Efficiently tunes the speaker enclosure to deliver deeper and more controlled low-end frequencies.
• Integrated Grille: Provides a durable mesh barrier to keep out dust and debris without restricting air movement.
• Acoustically Flared Design: Minimises port noise and "chuffing" by smoothing the transition of air exiting the tube.
• Robust Construction: Manufactured from high-grade black plastic for durability in home or professional audio setups.
• Standard 100mm Fit: Sized to suit a wide variety of subwoofer and PA cabinet builds.
