    Product details

    SB Acoustics SB12PAC25-4 4” Aluminium Mid-range Woofer

     

    The SB Acoustics SB12PAC25-4 is a 4 inch mid-range woofer with an aluminium cone. The SB12PAC25-4 uses a light-weight copper coated aluminium wire voice coil to create a responsive mid-range woofer. It also has a low Fs frequency which should allow for a low crossover point in a 3-way system.
