these should be pretty close if i haven't made any gross errors. we should double check in the morning...
the green, red, and blue sections correspond to the paths in hornresp.
i removed the flow directors and have not shown any bracing on the measurements in order to try to keep that as clear as possible.
lots of good bracing will be required.
the first couple measurements in the horn path in front of the driver are fairly important, try to get them exact. i have marked them with an = sign. the rest are marked with a tilde ~ which means get them close, but if they are off by a bit, it won't matter.
of course, performance will change a little bit if next to a wall, aimed into a corner, or other placement, so some experimentation will be required for optimal performance. i think aiming it into the corner will shift the whole response down a bit, but i'm not 100% on that.
the measurements are "inside panel to panel" so don't count the thickness of the wood. the measurements are the air space only.
attaching some small 1"x2" cleats next to where the panel go might help make assembly a little easier.
at least a second order high pass filter at 20hz as a starting point for protection would be advised.
