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.
