Genelec 5040 room modes

Genelec 5040 room modes

I've recently paired 5040 sub with 6010 speakers, my room is ok sized and nothing unusual (about 4 meters by 7) there's reasonable space for the speakers to breathe and furniture/carpets to break up some reflections etc.

I'm having a very hard time placing the 5040 sub without causing a massive 40hz bump, even with the -6db dip switches enabled... I've noticed it seems that it's impossible to place the 5040 sub next to a wall as this always excites 40hz and anything above that is too low - I've tried almost everywhere in the room  - in the middle between the speakers, in the corner, on the side all less than 60cm from the wall, adjusting the phase switches correctly,- the crossover point is 85hz unfrotunately and not adjustable.. I'm at a loss why the 5040 sub is so difficult to integrate -that 40hz bump is huge no matter what I do. I've even trying stuffing socks in the port.

Can someone recommend what else I can try? Unfortunately I can't place the sub and speakers (need to be equidistant) in the middle of the room, that's no an option, or for it to float in a zero gravity anechoic chamber. Is the 5040 subwoofer simply not compatible with being used next to a wall? Will the 7040 give better results - have a less excitable 40hz?
