        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.

        Very very good driver. It performes much better than its cost, very clear and detailed, huge bass for the size with the right crossover. Recommended to replace those old Seas from the 90's that were considered as legendary: 30 years have passed since then and this sounds much better and modern. Highly recommended
