What is the length of the horns in the picture, and the mouth diameter or radius? Is the Radian 750Pb a 2 inch driver? Some of the other posters also seemed confused about this too, and a web search did not provide any info from the Radian catalog that came up. Are you attempting to couple a 2 inch horn mouth to an existing 2 inch driver? Or are you attempting to couple a 2 inch horn mouth to a 2 inch driver with a smaller horn mouth adapter? There have been adaptors like this available to couple a smaller compression driver to a 2 inch horn mouth (I have some JBL examples) but it's to hard to generalize about whether this would be an improvement, it all depends on the driver and the horns in question. Do you have a way to measure this experiment? You can download Room Eq Wizard for free (REW for both PC and Mac) and with this and a decent test microphone you can evaluate the results.
