Default TinyHorn

Have a 12PS100 laying around and decided to do something with it. I worked in Hornresp and akabak today and came up with this Akabak script. Let me know what you think. I did draw it out in Sketchup as well

External dimms? Response looks good for a low midbass / subwoofer for portable rig that won't be playing much dub!

In light of recent talk with cone correction plates, I like the fact that the pressure on the cone is more evenly spread instead of having half the cone open past the s2 point...

Several friends that make their living in the industry had issue with it. I used to work design/install and still work on special projects for them when needed. We didn't make it a big discussion and I don't want to burn my friends and contacts I have. If you would like a copy of the plans and have no intention of using it for profit I'm still willing to share it by request. Hope that is a simple enough explanation
