    SB Acoustics SB23NRXS45-8 8″ Woofer

    The SB23NRXS45-8 woofer has a proprietary composition paper cone made in-house and a rigid cast frame with ventilated spider and large vented pole piece. A low damping rubber surround assures decent midrange reproduction. A shorting ring is used in the motor to reduce intermodulation distortion and improve inductance symmetry.

    This 8 ohm woofer features a Norex paper cone with special coating (Egyptian papyrus and long fibers), rigid cast frame design for minimal reflections, rubber surround, shorting ring to reduce distortion, and shallow 3-1/8″ depth.
