Reading a lot on the net about DCM Time Windows and various restorations / clones. I remember seeing them years ago in speaker buying guides and thought the looked neat but I have never heard them.
Now seeing as I have procrastinated on building my microtowers with top mount EL70, would mounting the drivers on adjacent sides create a Time Window experience? My listening room is small and is shared for other domestic considerations (read WAF). The speakers must be close to the wall.
Thoughts?

Keep the cross-section the same (and not too radical) and you will be fine with changing the shape of the cross-section. You could even make it time window shape, with an appropriate piece of curved material.

Here is a 1st approximation. One could likely get a close result with 10 or 12" SonoTube (or similar) by pulling apart or pushing together cut edges as necessary. You probably can't get 11".
A pieve of 10" or 12" PVC would be ideal, increasing or decreasing the front splay or moving the intersection of the baffle with the tube. Target is about 54 in^2, one would need to accomodate some internal structure and bracing to make the build easier (in which a piece of 12" ID PVC would be ideal.
Here is a 4' chunk. If you are careful with your length wise cut this would be close to perfect.
PVC 12" Pipe, 4' section

did not the Time Windows ( and Spica SC50) use "Sonotube" type compressed paper concrete forms for the curved sections?
