"I think the edge termination is less of an issue if the horn is operated above cutoff, but in the case of your midbass horns, with the floor coupling, things should be more interesting."

There would be no effect at all, of the arangement in the picture, at low frequencies around cut off,

The magnitude of the effect of objects on sound waves, depends strongly on to what extent the wave can couple to the objekt or if it can "see" the object. In this case of soundwaves in the half open you must look at how large the object is compared to the wavelenght.
As depicted here, my guess is that the effect would become stronger around 10kHz, that if there are any soundwaves at that frequency in the area where the tape is placed.
That does not mean that there will be no audible effect of the tweaking though, just less than posible, but maybe exactly what is asked for.
