SB Acoustics SB12PFCR-00 Passive Radiator

The SB12PFCR-00 Passive Radiator from SB Acoustics is a meticulously engineered component designed to elevate the low-frequency performance of your audio system. As a passive emitter, it works in tandem with an active driver to reinforce bass output, making it an ideal solution for compact loudspeaker designs where traditional porting is impractical. This unit is particularly well-suited for use in small sealed enclosures, such as bookshelf speakers or subwoofer systems, where it can deliver deep, articulate bass without the turbulence or chuffing often associated with reflex ports.

Technically, the SB12PFCR-00 boasts a nominal diameter of 122 mm and a cone area (Sd) of 50 cm², providing ample surface area for efficient air displacement. Its resonance frequency (Fs) is a low 34 Hz, enabling extended low-end response, while the maximum linear excursion (Xmax) of 9 mm ensures controlled, distortion-free movement at high output levels. The suspension’s mechanical compliance (Cms) of 1.2 mm/N and mechanical losses (Rms) of 0.32 kg/s are carefully calibrated for optimal damping and transient response. Part of the acclaimed PFC Paper series, this passive radiator features a paper cone for natural sound reproduction. By integrating this component, you can achieve a more immersive listening experience with enhanced bass extension and clarity.
