Indeed, this is absurd. Without getting the whole picture, I must say the room does not look that large for a speaker with such low frequency output. Second, pushing the speakers into the corner will only make matters worse. Third, these are transmission line speakers with, inevitably, quite a hump in the low bass. If all this comes together, there is a big problem. First thing would be to take out a measuring microphone and see what is going on. But really, forget about this nonsense.
