The greed of manufacturers who feel sorry for at least some semblance of legs to make, instead of indistinct squares, 2 mm thick.
Before that, there was a Heko Aurora center and the Germans were not too lazy in it, they made normal rubber legs with bolts.
Klipsch's body is 35 cm deep, which already pushes it decently away from the TV, and the phase inverter pipe requires it to be pushed at least another 20 centimeters forward. I think developers don't care about consumer convenience. Well, or it is meant to put a column in the center of the hall.
Such a volume requires much more rigidity. Make the walls thicker or put more spacers or paste over with a sound absorber. But there is none of that. Greed again.
The case, especially in the middle, responds to tapping with a low sound, and when played back, it resonates well, adding a rumble to male voices, making them louder, but less legible. Baritones are hard to listen to. And in general, the rumble of the case is wildly unpleasant.
Therefore, I had to play around with the equalizer in order to compensate for the rumble and increase the intelligibility of voices and the overall detail of the sounds.
