With Tympani ID, there is room for a ribbon tweeter next to the original pus-pull Magneplanar tweeter. The whole push-pull tweeter is a bit weird, its overall width is very wide, about 8 inches. The diaphragm itself is only 6 cm wide. It can be cut down to 10 cm and then the ribbon next to it. Of course, you need to rebuild the baffle., which is very flimsy. Still, it is a bit of a compromise as the original ID tweeter is crossed over to the bass drivers at 1 kHz. I think, a midrange driver operating down to 300-500 Hz would be better with the ribbon tweeter. The tweeter of the ID does have a bit of the cavity resonace often found in push-pull drivers. There is a peak at 7.5 kHz.
Below, the response without crossover, fundamental resonance seems to be at about 400 Hz.
Here the wide tweeter can be seen on the left. Having the drivers closer to each other help the imaging greatly!
