Actually, this second one sounds considerably better. In the first design, I didn't fasten the two reflectors of the horn to eachother because there was a slight misalignment. I was able to correct the problem in this second enclosure, so the two panels are securely fastened to eachother. It seems to have helped things. They are sounding a little better after a bit more listening.

And I actually *didn't* overcompensate with the additional enclosure, when I double checked it I made a major calculation error. After all displacement, a little polyfill and the internal volume should be right on target.

I'll keep ya updated!
