There is a reason that enclosure has such a triangle shape in it is too keep the phase tracking solid when listening to them on stands. The tweeter setback and off axis (veritically) required this orientation of the front baffle.By putting them upside down, it may appear that they are "pointing at you", but the midrange suck out and tweeter over emphasis really defeats all the work done on that very unique mixed xover topology and its positive resulting phase tracking in the 200 to 8000 hz range.
Another thing, the 0.22 uf were not specifically for by pass, but you will find that value changes by matched (A and B) pairs. They were used to tune each speaker to meet the "standard". Mostly based upon the measured unfiltered raw performance of each set of the Audax HF17 driver used.
