Yes, I know the feeling. The EC8010 theory of moving house is that the Hi-Fi is the last item to be packed/loaded (because playing music reduces stress). Therefore, it is the first item to be unloaded. It should be set up immediately (so that it can resume its function of reducing stress). Thus, it is positioned ideally, and frivolous items like furniture enter the room afterwards, if there is room, and they don't upset the sound.
Seriously, you can't do much about the bass boost, but you can ensure that the cancellations from each boundary don't coincide in frequency. 1m is the length of one wavelength at 344Hz, so your bass drivers (operating below 300Hz) are never going to suffer from cancellation because you can't move them far enough away. For your loudspeakers, the boost caused by the boundaries is helpful, and allows you to reduce drive to their amplifiers. (It looks as though it was deliberately designed to allow for room effects.) Conversely, your midrange driver is always going to have some cancellation due to boundaries, so it is important to make its distance to each boundary different, and not multiples of one another. Probably, the best results will be obtained with the loudspeakers back up against one wall, and spacing of the midrange driver to the adjacent wall 2/3 or 3/2 the distance to the floor.
I would say, "Experiment," but moving heavy loudspeakers is a trial. I move mine by tipping them and inserting hardback books underneath, removing the spikes, then sliding them into position. On a shiny floor like yours, inserting a (clean) doormat underneath the loudspeakers will allow you to slide them around without damaging your floor.
The loudspeaker: The only commercial Hi-Fi item where a disproportionate part of the budget isn't spent on the box. And the one where it would make a difference...
