I realize this is an old post. Short story, same challenge, blown tweeter in R-28F. Contacted Klipsch, they were extremely helpful. The R-15M horn with tweeter has the same tweeter, they recommended that I order and remove the tweeter from the horn and install. Have ordered the R-15M, and Klipsch doesn't charge shipping, same prices as what I saw on line. Hope this helps!
