Are there speakers that disappear regardless of the recording?

Sorry to say but the question you post is ridiculous. They will not be a speaker that disappears for every recording.  The question is like asking is there a speaker that will have bass for every recording.   There are some speakers that are excellent are disappearing but speaker placement is especially important at achieving this.  I’ve also seen and heard many speakers that are not particularly known as disappearing speakers but when setup correctly, they did disappear very well.  I feel room treatment and speaker positioning and placement goes a super long way in getting any speaker to disappear. 

If you want disappearance in locations other than the sweet spot, then you’ll have to look to Omni…. Ohm Walsh… Omni or as you mention MBL… Maggie’s aren’t in this category. I have never been a Ohm fan… but my partner had a pair when we met, she liked the indirectness of them.

As others have said, with some recordings your speakers will never disappear, ever.  

Now I'm speaking of listening from one position, not roaming the room. That said, the better the use and implementation of the acoustical space the more apt one is to realize the 'speaker disappearing act' on more and more recordings. 

Although (like in all cases) you can find some wonderful inexpensive speakers that do quite well at disappearing sonically, I have found that generally, GENERALLY speaking, more expensive world class speakers can do better at going away sonically more often than their more value-conscious and lower costing brethren. And that's fine. I have cheaper speakers I love quite a bit as well.

Very good electronics also help with openness.
