What speaker you're using?
I used R2500 so far no problem with boomy at certain frequency and the port was front firing too. Rear firing port need to be careful on corner too, I saw Dynaudio manual suggest that should place not less than 0.5m to avoid back and sidewall influence. Room size also will introduce the boomy sound.
You can try to position your ear level to the middle of tweeter and woofer of your speaker, and also position it in isosceles triangle.
Mine is the R1900T3.
I've tried all the basic positioning like the isosceles triangle, speaker height, tilting towards the ears etc, but no major positive outcome. Mine is actually rear ported not front ported.
I'm just worried that it might be because of my space's effect causing room modes and the bass response is interfering with each other and amplifying that certain frequency.
Mine is not in the corner but actually in the middle of the room. I'm in the living room so the space is quite big. My friend confirmed that the midbass is overpowering the treble.
The picture for my setup is in the post above us, on top of the page.
