Does speaker proximity to wall affect sound transmission?

I'm currently working in a downstairs room in my house, which shares one wall with the neighbours. They swear they can barely hear me, and I've never heard anything through the wall either, but my speakers are large and there's a fireplace on the wall in question so I'm concerned that they're just being polite. I'm currently set up against the wall opposite (2.2m away), but looking at my layout, I think I could treat the room better and get some space back if I moved my setup across so that the speakers would be against the shared wall. My stands are solid and there's very little vibration reaching the floor directly as far as I can tell, so I figure if they can hear anything it's predominantly speaker>airborne>my wall>their wall, and I'm hoping that if that's true, the location of the speakers in my room wouldn't be a big factor? I'm not well versed in acoustics though and wonder if there's something important I don't know about (some sort of airborne coupling between the speaker and wall, or something comparable to the proximity bass boost in microphones for example) that would make a big difference?

I'm sure even a ballpark guess at the actual level of transmission would require a lot more info than I have, I'm just curious to know if there's any acoustic principles at play that make this a bad idea by default? The neighbours have been very gracious during lockdown so I want to return the favour as much as humanly possible.

Thanks!
