SB ACOUSTICS SB23NRXS45-4 8” 4ohm Ferrite NRX Woofer Loudspeaker

Product Description:

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.
Besides 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.

Key Features:

• Soft low-damping rubber surround for improved transient response
• Shorting ring in-motor system for reduced distortion
• Vented pole piece for reduced compression
• Vented cast-aluminum chassis for optimum strength and low compression
• Shallow design (3-1/8″ depth)
• Non-conducting fiberglass voice coil former for minimum damping
• CCAW voice coil for reduced moving mass
• Long-life silver lead-wire
