The SB Acoustics SB12NRXF25-8 is a 4 inch 8 ohm midwoofer featuring a Norex cone with a foam surround and a rigid aluminium chassis. Norex is a proprietary paper based material comprised of wood pulp and selected natural fibres blended for an optimally strong but lightweight cone that, combined with the foam surround, gives excellent midrange extension with resolution and detail. This unit can be used as a fine midrange drive unit.
Also available in 4 ohms: SB12NRXF25-4.
