The Revelator woofers and subwoofers feature very rigid paper or aluminum cones 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 and perfect transient response.

  • 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)
