[QUOTE="JimGore, post: 56720, member: 3"] ...continued... 1. Response in the large horn 2. Response in the small horn Sorry, the scale on the two graphs are not the same for some reason ??? Please note that the SPL is not calibrated in either, so don't compare the actual output. The tweeter I am using in the small horn is not broken in yet - fresh from the packaging while the measurements in the large horn were using a broken in tweeter. I expect some of the bumpiness to go away after broken in. It looks like the small horn is actually more workable than the big one! The bump in response is about the same as that in the large horn - about 12dB, but the bump is narrower. I am still getting good response even low down on the scale which is something I was not expecting! The smaller horn will most probably give me a smoother response after I have the XO parts in place to tame the bump. Things are looking better and better from where I am sitting ;D More later. Cheers, Ian. [/QUOTE]
