As always... It depends!
Placing a speaker against a boundary wall at the front of the room (or better still, soffit-mounted within it) moves it into what's known as 'half space' because the sound can only radiate into a hemisphere. This significantly improves the efficiency of the bass reproduction, so the (uncorrected) speaker appears to have a bass boost. Some monitors have built-in EQ options to correct the frequency response for this condition, and when corrected there is a useful benefit in that the speaker gains some extra LF headroom for the bass amp/driver.
Moving the speaker away from the wall reduces and then removes that boundary effect, and most speakers are equalised to sound flat away from all walls... But, if the wall is acoustically reflective at low frequencies (and almost all are!) that reflected LF will add in some way to the direct sound from the speaker. Since there will be a short delay between the direct and reflected bass, there'll be a frequency-dependent phase shift and so at some frequencies there will be partial cancellations. The overall result is an inevitable dip in the frequency response at low-mid frequencies -- the centre frequency of the dip being related to the distance between speaker and wall.
The effect can be minimised by reducing the reflected energy, which means either a cardioid-response speaker (possible, but relatively rare), effective bass trapping absorbers on the front wall, or a very flimsy wall construction! :-) Alternatively, there's a school of thought that favours one or more carefully aligned subwoofers in the room to fill in the 'missing' energy.
There's an article on this low-mid response dip problem here:https://www.soundonsound.com/techniques/elephant-control-room
