Adjustable bass reflex port – BR70V/SW

The Intertechnik BR70V/SW adjustable bass reflex port offers a refined 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 acoustic environment and driver characteristics. Whether you are constructing a high-fidelity home audio system, a studio monitor, or a custom subwoofer enclosure, this port provides the flexibility needed to optimise performance without compromising on build quality.

This port is particularly well-suited for projects where space constraints or variable room acoustics demand an adaptable tuning approach. By simply adjusting the port length, you can shift the resonant frequency of the enclosure, enabling you to dial in a tighter, more controlled bass or extend low-end reach as required. The BR70V/SW is ideal for both new builds and retrofitting existing cabinets where fine-tuning is essential.

Technically, the port features a robust, precision-moulded construction that ensures minimal turbulence and port noise, even at higher output levels. Its adjustable mechanism is smooth and secure, allowing for repeatable settings. The 70mm diameter is optimised for a wide range of driver sizes, while the sliding tube design provides a generous adjustment range. This ensures consistent airflow and reliable performance across various enclosure volumes.

In summary, the Intertechnik BR70V/SW is a versatile and well-engineered component that empowers you to achieve the perfect bass alignment for your loudspeaker project, delivering both flexibility and sonic accuracy.
