Hi Freddy,
The 1/2 horns are all tuned to around 40-45Hz, It is the mouth area, vent throat opening of the port that provides the "hit".
I am no longer designing 1/2 horns, and am working on a 8 c.ft. bass horn good to 55Hz.
I also have found the plans for the Hypex 70 horn ( on my website)
- if anyone is interested, I will post them here. It uses a D120 12"
