But i am getting 2.5m instead horn length of 2.9m as claimed by the adrian mack. Driver used : Eighteen Sound 18LW1400 The original & redrawn drawing are posted as under. !)

The mouth is too small for 2Pi use.
This horn was probably designed to fire into a corner and the extra length is including the external air path too. ------------- djk |

Ok! But how he has calculated the extra length? I know this is designed with .5 pi. I just want to learn how he has designed. |

I would say he added the length from half-way into the corner to the front edge of the cabinet. ------------- djk |
