Maybe i'll start a new thread about my "feelgood" speaker project
Click the image to open in full size.
note the tweeter is HDS but with a frontplate for my main speakers.
Have original frontplate now.

Do I see step back top also? Maybe some felt on the ledge to control diffraction. Those drivers are a good choice in combination. I see you like white color too.

I had that idea too, using the tweeter on top of the woofers cabinet but I did not want to alter it since I was not sure what would happen. Looking promising, nice to see it!

It would be an unpredictable outcome. Would need crossover redesign. Cabinet diffraction and centers of wavefront emission are integral to the development of any speaker. At least they should be.

Yeah Salas, I suspected it would mean a different speaker. Maybe if I make a cheap 2-way learning project that idea is worth trying. I was thinking that if you can place tweeter on top but keep the same volume for woofer it would be possible to skip the stands since the tweeter is higher.

The two drivers need keep centers close together. Else, severe lobes are going to form around the transition band.

Yes, but if you make the centers like you said, with the woofer high up in its cabinet, that should be ok, right? Like Smutzigers solution.

Depends in what region this brings the floor reflection destructive interference in combination with listening distance. Center of gravity and mass of construction, impact to box resonance, diffraction pattern due to woofer's emanation point and if it is best point up high, litres you need and if allowing to get enough base area to be stable if building it high, many things. What you will need, is a calibrated mic, handy soundcard, handy software like HOLM Impulse, reading many other projects, time, ideas to test, and passion.
