I am attempting to compile a table of mouth size, throat size, length and Fc for various horns. The throat size for a K-400 (K401 is of interest. Can some good person out there measure the diameter of the port on a K55 with an inside measuring micrometer for me. Please! I think that all screw -on drivers of the type have the same dimensions. Thanks 10E6, Wm Gil McD
