The SB Acoustics SB20PFCR30-8 Full-range Woofer represents a masterful blend of engineering precision and natural sound reproduction, designed to elevate any audio system with its remarkable broadband capabilities. This compact yet powerful driver is ideally suited for high-fidelity two-way configurations or dedicated subwoofer systems, where its ability to cover a wide frequency range with exceptional clarity truly shines. Whether you are building a custom home theatre setup, a refined stereo pair, or a professional monitoring solution, this woofer delivers a cohesive and immersive listening experience that brings music and film to life.

At the heart of the SB20PFCR30-8 lies a carefully engineered paper cone, chosen for its lightweight yet rigid properties that ensure natural, uncoloured sound across the spectrum. The 30.5mm voice coil, combined with an impedance of 8 ohms and a DC resistance of 5.6 ohms, provides efficient power handling and controlled thermal performance. With a sensitivity of 90.5 dB (SPL 1m/2.83V) and a resonance frequency of 34 Hz, this woofer offers impressive low-end extension. The total Q factor of 0.37, alongside a mechanical Q of 2.66 and an electromagnetic Q of 0.43, indicates excellent damping and transient response. A maximum linear excursion of 5.75 mm ensures dynamic, distortion-free output, while the 0.84 mH voice coil inductance contributes to smooth high-frequency roll-off. Built with eight mounting holes and a nominal diameter of 203.2 mm, this driver integrates seamlessly into a variety of enclosures, making it a versatile and reliable choice for discerning audio enthusiasts.
