I love that pic! I've been considering to make 12 for ages too, but I consider:

Extending to pallet size 120x80 cm (u could use that too:-)
Changing throat not to blow drivers: (See page 16 in this thread)
Testing Porting to cool rearchamber & limit excursion + add a little lowend
+Add wheels to bottom 45 degrees plate & a handlebar at the top rear

Just too busy, so still being a dreamer on this one...
I tried other options though, so I did something :-)

I just bought 4 pcs, so I could be interested in 8 more:-)

Actually the plan is just to try them out, then if I like them I'd most likely do my own version like stated above, unless a pile drops down on me and saves my lungs from sawdust:-)

100% Ken

Dub specialist sound comes first if he sold them to u! I won't start no overbidding! :-)
But let me know if the deal doesn't come through for some reason...

You will need porting to reach 30, graph only says 40 without :-(
-Or build a larger horn, like the Amano, SBH etc.
