The Revelator woofers and subwoofers are characterised by very stiff cones made of paper or aluminium that operate over a wide frequency range. Combined with the Scan-Speaks linear suspension and the patented Symmetrical Drive (SD-1), the result is very low distortion and a smooth and well-tuned frequency response as well as perfect transient reproduction.


Features:
  • 9" (23cm) Subwoofer with Aluminium Diaphragm (Black)
  • Patented symmetrical drive motor design
  • Rubber surround
  • Ferrite magnet system with rubber coating
  • Black anodized rigid aluminium basket
  • Die-cast aluminum basket vented under center spider
  • Gold terminals

Data:
  • Power handling (nominal/music) = 225 W
  • frequency range = 20-800 Hz
  • Resonant frequency fs = 21 Hz
  • Impedance R = 4 Ohm
  • Sound pressure level SPL = 82 dB (2.83V; 1m)
  • DC resistance Re = 3.45 Ohm
  • Force factor BL = 9.3 N/A
  • Voice coil inductance L = 0.45 mH
  • Effective diaphragm area Sd = 232 cm2
  • Moving mass incl. air load mms = 101 g
  • Equivalent volume Vas = 45 l
  • Total free air quality Qts = 0.47 (Qms=4.8, Qes=0.52)
  • Voice coil diameter = 50 mm
  • Linear deflection xlin = +/- 13 mm
  • Mounting diameter d = 225 mm
  • Outer diameter d = 255 mm
  • Mounting depth (not milled in) t = 141 mm

Enclosure recommendation:

  • closed cabinet with 22 litres
  • from 35/22 Hz (-3dB/-8dB)

cabinet recommendation:

  • 89 litre BR-box
  • with HP70 port of length 32 cm
  • from 16/14 Hz (-3dB/-8dB)
