Product information "SB Acoustics SB34SWPL75-3-DV"

The SB Acoustics SB34SWPL75-3-DV 12" woofer uses a large 3" voice coil on a cast aluminium chassis. Hard Paper proprietary cone materials made in-house for consistency. Low damping SBR rubber surround with high exertion and resilience. Open structure cast frame for reduced reflections and compression. Aluminium alloy for light weight, non-magnetic and extra rigidity.



  • Hard paper cone for improved piston operation (made in-house)
  • Vented pole piece for minimum compression
  • Vented cast aluminum chassis for optimum strength and low compression
  • 3 copper voice coil (4-layer) for improved power handling
  • Long life silver lead wires
  • Low damping medium hardness rubber surround for improved linearity and power handling
  • Non-conducting fiber glass voice coil former for minimum damping


  • power handling (continuous/programme) = 300 W
  • resonance frequency fs = 27,5 Hz
  • impedance R = 2x3 Ohm
  • sound pressure level SPL = 90/85 dB (2,83V; 1m)
  • DC resistance Re = 2x2,5 Ohm
  • force factor BL = 9,7/19,5 N/A
  • voice coil inductance L = 1,4/6,1 mH
  • effective piston radiating area Sd = 458 cm2
  • effective mechanical mass incl. air load mms = 231 g
  • equivalent volume of compliance Vas = 43 l
  • total Q factor Qts = 0,48 (Qms=5,62, Qes=0,52)
  • voice coil diameter = 75,6 mm
  • mounting diameter d = 302,5 mm
  • overall diameter d = 346,2 mm
  • mounting depth (not countersunk) t = 146,5 mm
