Product details
The SB Acoustics SB23NRXS45-4 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 woofer has a large 1.75″ diameter voice coil with 6.5mm x-max on a non-inductive fiberglass former.
