Speakers that disappear

In my experience the best speakers at disappearing tend to be planar - the original Quads were quite good and ones that I still own, primarily because of this particular attribute, are Martin Logan CLS.

This, Why I liked MQA so much, the hi rez mqa was so spacious sounding that the room, speakers and everything in it disappeared.....

  I find the further I can get speakers away from reflecting surfaces the easier they vanish audibly. 

RE:  the Quad ESL 57's, which are the best sounding speakers ever created (with the right set up) - both the Maggie LRS+ and Harbeth 30.1/2's and 40.2/3's (with the right set up) (which I also have) sound very, very close to the ESL 57's!  All of the Harbeths sound very similar to them.

@bassdude +1!

There was of course never any such moniker as “ESL-57,” except in retrospect, to distinguish it from its distinguished successor the ESL-63. Designed by the legendary Peter Walker and actually introduced in 1956, it was called simply the Quad ESL, but soon became known as “Walker’s little wonder.” Little wonder: For top-to-bottom clarity, coherence, transparency, resolution, openness, naturalness, and a disappearing act that still inspires awe, the ESL established and remains to this day (even though production ceased over a quarter century ago) a reference standard among countless designers and reviewers (including the undersigned) across the globe. Despite undeniable limitations—inability to play very loud, lack of deep bass, quite directional highs—it tops virtually every list of the best, the greatest, the most significant—supply your own category—audio products ever made. Why? Because at the dawn of the stereo era this “little” wonder demonstrated what was possible in most of the essential areas of speaker performance so validly that from a certain point of view the subsequent history of speaker design has been catch-up.

I had several speakers in the garage that disappeared completely. I suspect my wife put them out on electronic recycling day but she swore she did not. Still, where are they?
