[QUOTE="Peter Morris, post: 213418, member: 652"] Hi Grant, The roll off you see can also be a function the cut off frequency of the horn they used for the test. In this case RCF don't say but I suspect they used the same horn for both driver tests. Here is the ND 950 on the HF 950 and the B&C DE1090 [URL]https://audioxpress.com/article/Test-Bench-RCF-ND950-Neodymium-Compression-Driver-and-HF950-Horn[/URL] [URL]https://audioxpress.com/article/test-bench-b-c-speakers-de1090tn-compression-driver[/URL] [/QUOTE]
