Thanks for the thoughts,

I was just on the phone with a guy who sells prototyping materials; we discussed the idea I had this weekend... His opinion is that it should work. If so, it will really make the process much quicker.

I will keep this in mind; it would very much be to my benefit.

"...You shall not put a LF source between the MF channels – very bad for imaging..."

Yes I thought you might say that.

The lower-bass enclosures started off located on the outiside, just as in your illustration. The CAD image was done while conducting an experiment : I wanted to try putting the existing horns closer to the side walls for better coupling.

Result : Yes I got better coupling (of the bass horn particualrly), but the bass got muddy and worst of all, all intimacy was gone. Another thing I noticed : Anything even slightly dynamically compressed was just unlistenable.

It took me a couple days to realize what was going on... This was not the only change I made; on top of that, I was not getting enough sleep to trust my ears. In fact I had to pull the frames away from the side walls before understanding the extent of the damage. That's what I was doing last night. I still have to move the lower-bass enclosures back to the outside.

Btw, I have also moved the 180Hz horn back up, leaving more space for the tweeter.

Regarding the set up you illustrate above... This may be possible (I need to measure); it would require that I modify the house a bit.
