Curved Speaker Cabinet Port Tubes 66 mm Inner Dia. x 280 mm Outer Length

These curved speaker cabinet port tubes offer a refined solution for achieving deeper, more controlled bass response in your custom loudspeaker builds. Designed specifically for bass reflex enclosures, they are engineered to minimise air turbulence and reduce the unwanted chuffing noise that can plague straight port designs, ensuring cleaner, more articulate low-frequency output.

Ideal for both DIY audio enthusiasts and professional cabinet makers, these ports are particularly well-suited to high-performance subwoofer and full-range speaker projects where precise bass tuning is essential. Their curved geometry allows for smoother airflow, which not only enhances sonic clarity but also enables more flexible placement within the cabinet, helping to optimise internal volume usage without compromising acoustic integrity.

Each tube features a 76mm internal diameter, providing ample cross-sectional area for substantial air movement. The curved profile is carefully moulded to maintain consistent port length and tuning frequency, while the smooth interior surface further reduces friction and distortion. Constructed from durable, rigid material, these ports resist resonance and vibration, contributing to a solid, uncoloured bass foundation.

Whether you are upgrading an existing design or starting a new build, these curved port tubes deliver reliable performance and a professional finish, helping you achieve the tight, authoritative low end your project deserves.
