I am working on a tall, skinny TMWW speaker.
I have seen the comments that a tall, skinny speaker is a MLTL due to its nature, whether I call it a basic bass-reflex or not, so I thought I would take that seriously and model it as a MLTL in Hornresp.
To make things work, I would seal off the top portion with the midwoofer and have a simple rectangular volume for the two woofers. I model the woofer placement as the center of the two actual woofers. In Hornresp, I can actually get a very good model for this. BUT, while the overall size is acceptable, the pink shaded area is wasted space (see image to the left).
Would it work, and is there a way to model it in Hornresp, to open up that area and have an irregularly shaped "line", as in the image to the right?

It will work, there are many commercial loudspeaker with exactly the same enclosure build. A resonance will emerge across the enclosure height, but It is easy to damp it with a piece of foam behind the mid enclosure (at lower part). Experiment with tube location (height) for minimal resonance.
Volume for the mid should be optimal (read: small), but it depends on the crossover frequency.

Not exactly.
