I will begin testing drivers for a major car audio manufacture shortly. I am looking for a local individual or business that can measure the Thiele-Small parameters of loudspeakers. I will mostly be testing subwoofers. I am looking for somebody to serve as a technical reviewer and verify my measurements independently. This individual will also need to perform measurements on random samples generated from production runs of the driver (Quality Control testing). If there are some one in the East Tennessee(Tri Cities, Knoxville) / Western North Carolina (Asheville) area that has this capability please contact me. jasonhwatts@earthlink.net
