Scanspeak 30W/0-00-00 Passive Radiator - Discovery Range

Scanspeak 30W/0-00-00 Discovery 12 inch Passive Bass Radiator.

Discovery logo

Passive Sub-Bass Radiator (sometimes called ABR or auxiliary bass radiator) with an adjustable weight for optimising the resonant frequency. The rigid anodised alloy cone has an exceptional maximum excursion of 56mm and the resonant frequency (Fs) is very low at just 9.5 Hz.

Designed to be driven by the Scanspeak Discovery  30W/4558T00  Sub Woofer - together they make a formidable pairing.

Ideal for high power domestic and in-car sub bass systems.

Key Features:

  • Rigid Black Aluminium Cone
  • Die cast Aluminium Chassis
  • Adjustable Weight for optimal tuning
  • Coated Sandwich Fibre Glass Dust Cap
  • Huge maximum excursion ± 28 mm

Basic parameters:

Resonant frequency (fs) 9.5 Hz Nominal impedance (Zn) - Ω
Mechanical  Q factor (Qms) 14 DC resistance (Re) - Ω
Electrical Q factor (Qes) - RMS power handling - W
Total Q factor (Qts) - Sensitivity (2.83V/1m) - dB
Equivalent volume (Vas) 200L Chassis diameter 308 mm
