I have a copy of an article New Loudspeaker with Extended Bass written by William H. Watkins published in Audio magazine in December, 1974.
This is a technical five-page paper discussing enclosure and crossover design for the Watkins woofer, and includes pertinent graphs and formulas.
I don't know if this article is the "white paper" referred to in this thread, but I have made a PDF scan of the article.
I could post the PDF file here, but I don't know if doing so would violate any copyright laws. Does anyone know?
I can email a copy of the article on request.
