Adjustable bass reflex tube – BR50V/SW

The Intertechnik BR50V/SW adjustable bass reflex tube offers a sophisticated solution for achieving precise low-frequency tuning within your speaker cabinet. Designed for audio enthusiasts and DIY loudspeaker builders, this component allows you to fine-tune the bass response to match your specific enclosure and driver characteristics, ensuring a balanced and immersive soundstage. Whether you are constructing a high-fidelity home audio system, a custom subwoofer, or a professional studio monitor, this port provides the flexibility to optimise performance without the need for multiple fixed-length tubes.

Technically, the BR50V/SW features a variable effective tube length, enabling you to adjust the tuning frequency by simply rotating the inner section. This eliminates the guesswork often associated with fixed ports and allows for real-time experimentation during the design phase. Constructed from durable, high-quality materials, it ensures minimal resonance and distortion, preserving the integrity of your audio signal. The port is designed for easy integration into standard cabinet cutouts, making it a practical choice for both new builds and retrofits. With the ability to dial in the perfect bass extension, this adjustable port is an invaluable tool for any serious loudspeaker project, delivering controlled, accurate low frequencies that enhance your listening experience.
