Speakers that disappear

check out the monitor audio platinum 100s if it's in your budget or the gold 100s.

@willy-t  has it right.  Ignore all the specific speaker recommendations.

Quality of Recording is really important, placement of listening chair.  And volume.

Unfortunately, speakers are always at the mercy of recording quality.

While I agree that all speakers “can” disappear to some extent or another and that things like the room and recording quality also matter significantly, some speakers still just inherently and more easily and completely disappear as a sound source better than others regardless of other factors.  Joseph Audio does this and I’ll add ProAc in there too as standouts although there are certainly some others that pull this off well.  So to say individual speaker recommendations are not helpful in this regard is simply not accurate in my experience because certain brands do excel at disappearing as a sound source better than others, and that’s what the OP was asking for here. 

Most comments in this thread are correct and setup is key. I will add low defraction designs will help too. I am not too much into stand mount speakers and I can’t not recommend anything but speakers with round smooth surfaces and narrow faces will help (think Vivid Audio, Kef blade, etc).
