Post Subject: The coupling from chamber to hornPosted by be on: 7/16/2008
Very nice project you have, an inspiring effort!
Loking at the pictures it seems to me that you are using felt in front of the chamber front plate to seal the coupling between the horn and the chamber?
This could cause some problems if the felt sheat is open towards the horn throat.
Here the sound presure is at the highest and and the sheat could function as a strongly dampened porous chamber, depending on how much the felt is compressed.
Since the area of the front of the felt sheat is quite large it might be difficult to compress it enough, dispite the large bolts to get rid of the porousity.
My experience with placing felt in the throat area is that it is very effective in making the sound go flacid.
Maybe, to avoid possible problems, you could use a rubber o ring or some corck?
