[QUOTE="JimGore, post: 56368, member: 3"] Don't have too much to report this weekend except that I am busy making a smaller tweeter horn. If successful it will be used in the surrounds and centre channel. The horn's in the big floorstanders mouth is about 16cm internal diameter. I am using the same mold I did with the big ones, but cut the fibreglass cone down to a mouth of 10cm in diameter. Theoretically the "bump" in response should move up in frequency, but I will be able to move the tweeter closer to the midrange, thereby allowing for a higher XO point if needed. More than anything I am really interested to see what happens seeing as the throat and horn angle, etc will remain constant with the bigger ones. Also using the big round-over for the lip. I have a gut feel that the horn's efficiency will go down a bit too, but I will have to wait and check that with the microphone. Will post pics as soon as I have the sample done. Cheers, Ian.
