        SB Acoustics SB20PFCS30-7 – 8-Inch Woofer Driver

         

        The SB20PFCS30-7 is a purpose-built 8-inch woofer from SB Acoustics, ideal for use in sealed enclosures with a high Q design approach. It features a proprietary cone made from natural fibers for improved tonal accuracy, supported by a compliant foam surround for high transparency and midrange precision. The driver integrates a large spider and a vented motor structure with a 30.5 mm diameter voice coil and a 16 mm coil height, offering 11 mm of linear travel peak-to-peak. With a free air resonance of 39 Hz and a sensitivity of 88 dB (2.83V/1m), it delivers balanced performance across low and mid frequencies. Additional highlights include a non-resonant vented plastic chassis and long-life lead wires, contributing to its durability and acoustic integrity. Ideal for sealed cabinet designs where tight bass and clean mids are essential, the SB20PFCS30-7 is rated at 40 watts nominal power handling.
