That’s a very tough room. I agree with @Poleepkwa’s suggestions. One of the reasons your nearfield setup sounds so much better is because you are getting mostly direct sound from the speakers. In your other room however most of what you’re hearing is reflected sounds mixed with the direct sound, which will become a mess. You must try to get as much direct sound as possible and minimize reflections. So get the speakers even closer to you, and if you can, yes try to move the speakers past that post if you can (I would try to move slightly ahead of it to reduce baffle reflections). And point them toward you as he suggested. And you really, really need some absorption in there - a thick rug would be a good start. Take the subs out of the chain for now until you get things working with the mains. Once the mains are good, then try to blend in the subs, if you even need them. Never put subs into an already shitty sounding setup. If you get the mains working well enough, then you have a shot at blending the subs in, but no guarantee (you’re definitely going to have to mess with placement). Honestly, those speakers could simply be too much for that space, and since you’re likely going to need to be so close to them, the highs/mids/lows may not integrate well because of the height of them (this is another issue with tall speakers in very small rooms). Ironically, a horn or waveguide based tweeter (like your previous speakers) would probably be best for that room, again because it will limit the horizontal (and vertical) dispersion and reduce the amount of reflections you’ll get and give you more direct sound.
