Description

SB Acoustics SB23NRXS45-8, 8" Woofer

SB Acoustics 8" coated paper cone woofer. 8 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.

This 8 ohms woofer featers 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. Qts of 0.38 allows for either sealed or vented boxes.

Box Recommendations

  • Sealed box of 0.75 cubic feet with 50% filling has an F3 of 55Hz.
  • Vented box of 1.0 cubic feet with 2" diameter vent by 7" long has F3 of 45Hz
  • Vented box of 1.25 cubic feet with 2" diameter vent by 5" long has F3 of 40Hz
  • Vented box of 1.75 cubic feet with 3" diameter vent by 8" long has F3 of 35Hz, power handling in this bigger box would be reduced

  • 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 aluminium chassis for optimum strength and low compression
  • Shallow design
  • Non-conducting fiberglass voice coil former for minimum damping
  • CCAW voice coil for reduced moving mass
