Hello Romy, thank you for the answers. Your horns have a round mouth, but their profile is not spherical. That is the profile of the Avantgarde Horns you formely had - apparentyl you have anayzed them intensively, could you elaborate what problems you found ? Kugelwelle = Spherical Wave profile invented by Klangfilm-Siemens. Not Tractrix, on Wikipedia it is also wrong. My setup is : double tapped horns up to 150 Hz. Midbass-Horn from 150 - 500 Hz, then a 2" CD and a 1" CD.If you use the excel sheet by volvotreter, for a tractrix horn of 80 Hz cutoff the usable frequency starts at 170 Hz, lenght is 93 cm. looking at a horn by JLH it seems that he has added a long tube at the throat - is this to increase bass-loading ? have a nice day !
