Bass reflex tube – HP50

The Intertechnik HP50 bass reflex tube is a precision-engineered component designed to enhance the performance of your loudspeaker projects. This straight port, with a 50 mm inner diameter, is crafted to reduce unwanted port noise and improve low-frequency output, ensuring your speaker build delivers clean, powerful bass. Ideal for DIY audio enthusiasts and professional cabinet designers alike, the HP50 is perfect for use in vented enclosures where accurate bass reproduction is critical, whether you are constructing a high-fidelity home audio system or a robust PA speaker. Technically, the tube features a smooth internal surface that minimises air turbulence and chuffing, while its rigid construction prevents resonance that could colour the sound. The 50 mm diameter is optimised for a wide range of driver sizes and enclosure volumes, and the tube can be cut to your exact length requirement for precise tuning. Finished with a durable, matte black exterior, it integrates seamlessly into any cabinet design. With the HP50, you achieve reliable, low-distortion bass extension that elevates your loudspeaker project to professional standards.
