SB Acoustics SB29NRX-00 10" Passive Radiator

The SB29NRX-00 10" Passive Radiator from SB Acoustics is a meticulously engineered component designed to enhance the low-frequency performance of loudspeaker systems. By replacing a traditional port, this passive radiator delivers deeper, more controlled bass extension without the turbulence and chuffing noises associated with vented enclosures. It is an ideal solution for compact speaker designs where port length would be impractical, or for sealed enclosures seeking to augment output below the system’s natural roll-off.

This unit excels in high-fidelity home audio, subwoofer, and multi-way speaker applications, particularly where space is at a premium. Its generous 17 mm maximum linear excursion allows for substantial air displacement, ensuring powerful, distortion-free low-end reproduction. The resonance frequency of just 10.2 Hz, combined with an equivalent volume of 65.98 litres and a mechanical compliance of 0.48 mm/N, enables seamless integration with a wide range of woofers and amplifiers. The mechanical Q factor of 10.8 contributes to a well-damped, accurate response.

Part of the acclaimed NRX Norex series, this passive radiator features a robust 254 mm nominal diameter and a high-quality suspension system. Its construction ensures long-term reliability and consistent performance, making it a superb choice for both DIY enthusiasts and professional designers seeking to elevate their audio projects.
