SW312TU02 impedance response


	Important! Please observe that the text files for download are actual measurements of the drivers measured in an “infinite” baffle, without any enclosure. Measuring the drivers in a finite baffle (like the baffle of most speaker cabinets) or in any size of enclosure will lead to different response curves.
