SOunds good! Now you've got us all excited, and have to share with us how it sounds/measures, and if it works well, do post the dimensions for others to build! ![](http://www.audioroundtable.com/emoticons/smiley.gif)
These are nice drivers. What I like about them is the 100 hz to 5 khz flat curve, and the decent freq extension.
They are sensitive to placement, though.
