Made some progress with this after being put on the sidelines for a while.
The ports on the first horn have been moved to the sides, it was not as hard as I thought it would be and it looks better too.
Also added some more dampening material to all three chambers which helped flatten the low end out alot.
I got the DNA-350 CD from Erich and mounted it up also, it was almost a drop in replacement as far as the crossover goes needing only two resistors changed for this:
I might fix the bump at 250hz if it bothers me, impeadance drops close to 3 ohms at 1000hz but that does not bother me.
The second one is almost done, I still need to apply gasket to all the removable panels and mids. Need to seal up the mids mount all the drivers, run wires for the drivers into all the chambers and build the crossover.
