Description

SB Acoustics SB23NRXS45-4
8" Coated Norex Paper Cone Woofer

SB Acoustics 8" coated paper cone woofer. 4 ohms impedance. The 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. The woofer has a large 1.75" diameter voice coil with 6.5mm x-max on a non-inductive fiberglass former. 234mm frame, 205mm cutout.
