I would add a few of myne but looking at urs compared to myne im not so sure ive quite got this all worked out properly yet, horn length is my main problem here, does it start from the throat or the driver?

this is the main trouble!
I start measuring horn lenght from the end of the driver, the front of the driver is the compression chamber. But, if there's a letter box throat I start measuring from the middle of the areas of the letter box. I use datainf measure software and inkscape for the measurement. |

im pretty sure the h15 simulation is wrong, if you put it into hornresp and have a look at the schematic youll see that the expansion and the spl plot is a bit querky? any thoughts? myne looks fine and the spl plot seems more like what id imagine it to be
