SB Acoustics SB20PFC30-8 8" Paper Cone Woofer

The SB20PFC30-8 from SB Acoustics is an 8-inch paper cone woofer that delivers a compelling blend of natural warmth and controlled performance, making it an excellent choice for high-fidelity audio projects. Designed as a bass/mid-bass driver, it excels in both two-way and three-way speaker systems, offering articulate low-end reproduction and a clear, detailed midrange that brings music to life.

This driver is ideally suited for use in bookshelf speakers, standmount monitors, or as a dedicated mid-bass unit in multi-way designs. Its well-damped paper cone provides a smooth frequency response, while the robust motor system ensures low distortion even at higher output levels. With a total Q factor (Qts) of 0.37, it is optimised for vented enclosures, allowing for extended bass response and efficient power handling. The maximum linear excursion (Xmax) of 5.75mm further enhances its ability to produce deep, controlled bass without strain.

Technical highlights include a sensitivity of 90.5dB (1m/2.83V) for efficient operation, a resonance frequency (Fs) of 34Hz, and a 30.48mm voice coil for improved power handling and thermal stability. The equivalent volume (Vas) of 65.98 litres and low DC resistance (Re) of 5.6 ohms complement its 8-ohm impedance, making integration straightforward. Whether for a custom build or a replacement driver, the SB20PFC30-8 offers authentic, room-filling sound with the trusted engineering of SB Acoustics.
