The SB16PFC25-4 from SB Acoustics is a 6-inch paper cone woofer that delivers a remarkable balance of accurate bass and articulate midrange performance. As part of the acclaimed PFC Paper series, this driver is engineered to bring natural, uncoloured sound to any audio system, making it an excellent choice for both music enthusiasts and professional builders.

This versatile woofer excels in a variety of applications, from two-way bookshelf speakers to dedicated subwoofer systems. With a total Q factor of 0.34 and a resonance frequency of 35 Hz, it is ideally suited for sealed or ported enclosures, where it can produce tight, controlled low frequencies. Its 89.5 dB sensitivity ensures efficient power handling, while the 4-ohm impedance allows for flexible amplifier matching.

Technically, the SB16PFC25-4 features a lightweight paper cone that minimises breakup modes for cleaner sound, paired with a 25.4 mm voice coil that provides excellent thermal stability and power handling. The 4.5 mm linear excursion (Xmax) enables dynamic bass response without distortion, and the low voice coil inductance of 0.56 mH contributes to extended high-frequency performance. With a DC resistance of 3.2 ohms and an equivalent volume (Vas) of 32.56 litres, this driver is meticulously engineered for precision.

Whether you are designing a high-fidelity home audio system or a custom subwoofer, the SB16PFC25-4 offers the build quality and sonic accuracy that SB Acoustics is renowned for, delivering a natural, engaging listening experience.
