Finished the 7 Pi midhorn over the winter break. Gained some new woodworking skills, that's for sure! For example, take cursed thing to old mate down at the woodyard... put it through the tree-ripping bandsaw. Problem solved.

Had the crossovers built by Wayne on hand, mounted them in boxes. Removed the HF gear from this project http://audioroundtable.com/forum/index.php?t=msg&th=11661&start=0&
(4 Pi derivative), made a cover plate for the hole.
Mounted the HF unit in box and... SHA-ZAAM!

Have a couple of queries, if I may.
My three-year-old son has already made gestures towards reaching up and poking the dust caps. It's embarrasing to hear a grown man scream like a girl. Would acoustically-transparent cloth glued to the inside of the horn throat square be a problem?
What is the theory behind the 'backward' facing woofer? Is this to utilise the corner principle, negate floor bounce? In theory or practise, would a forward facing woofer as I currently have sound any different?
As pictured, the walls (to the left, curtains covering ancillaries, to the right window curtains) would diffract sonic reflections from the midhorn (and tweeter)- yes? Currently in the process of constructing doors to cover both of these curtained areas (due to a desire to secure the hi-fi gear and dust is a big problem on these components from the curtains). Which surface would be optimal- a diffractive, reflective, absorbative (i.e. rigid fibreglass acoustic panel) or combination from the above?
