The SB Acoustics SB15CAC30-4 is a 5 inch 4 ohm midwoofer featuring a geometrically reinforced ceramic cone. The ceramic layer is bonded to an aluminium substrate, this combination of materials results in an excellent stiffness to damping ratio; consequently, the midrange distortion figures are class leading. Like other drive units in the CAC range, the SB15CAC30-4 has a fine detailed sound and is largely impervious to the effects of daylight and domestic humidity making it an ideal alternative to paper / pulp types.
Also available in 8 ohms: SB15CAC30-8
