SB Acoustics SB13PFCR-00 Passive Radiator

The SB13PFCR-00 Passive Radiator from SB Acoustics is a meticulously engineered component designed to elevate the low-frequency performance of your loudspeaker system. By replacing a conventional port, this passive radiator delivers deeper, more controlled bass without the turbulence and chuffing noises often associated with ported enclosures. It is an ideal solution for compact speaker designs where space is at a premium, allowing you to achieve extended low-end response in a smaller cabinet.

This passive radiator is perfectly suited for use in high-fidelity home audio speakers, subwoofer systems, and automotive audio installations. It works in seamless conjunction with an active driver, effectively tuning the enclosure to produce rich, articulate bass that enhances the overall listening experience. Whether you are building a custom pair of bookshelf speakers or upgrading an existing design, the SB13PFCR-00 offers a versatile and reliable upgrade path.

Technically, the radiator boasts a resonance frequency (Fs) of just 23 Hz, enabling impressive low-frequency extension. Its mechanical Q (Qms) of 5.9 ensures controlled damping, while a maximum linear excursion (Xmax) of 10 mm allows for substantial air displacement. The cone area (Sd) of 87 cm² and a suspension compliance (Cms) of 1.33 mm/N contribute to its precise, responsive behaviour. These specifications combine to deliver a passive radiator that is both powerful and accurate.

In summary, the SB Acoustics SB13PFCR-00 is a high-quality passive radiator that offers a refined solution for enhancing bass performance. Its thoughtful design and robust technical parameters make it a valuable addition to any serious audio project.
