SB Acoustics Woofers NAC

SB Acoustics woofer (aluminum cone woofer, 8 ohm impedance) cone was formed with geometric features to reduce resonance and improve rigidity. The woofer has 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.
