Default Invisible speakers: who has achieved, or experienced this?

Okay, I'm not talking about enclosures that have great WAF, rather systems that by whatever means create an acoustic "illusion" that is so convincing that it becomes, to all intents and purposes, impossible to "see", or become mentally aware, that the speaker drivers are the origin of the sound. Items like the MBL "watermelons" are known for pulling this off to a large degree, but there are other ways of doing it ...

Pano has been 'outed' on this, see Linkwitz Orions beaten by Behringer.... what!!? and following pages for some discussion on the phemonenon, and its "spookiness". So, I'm curious whether anyone else on this forum has come across it, and what the circumstances were, etc, etc ...

If you're not sure whether you've had it, then it means that you haven't: it's such a distinct sound experience that, as Pano says, forever more it remains a key audio memory.

Experienced many times. One of the objective for me.

The simpler the crossover (full-range is of course the best), the easier to achieve that. The driver must have low distortion. Very hard with exotic light-weight cone material, easier with paper based.

For me, it is just a matter of getting clean reproduction from each of the drivers, and the drivers being in phase.

spooky realism? Yes thats the whole point of this lark. Speakers that disappear? Not an accurate phrase, in my opinion. Try playing birdsong, Then claim that the speakers'disappear'.....image is just as important as localised HF. With CD devices (my experience) it is easy to locate that single birdsong coming directly from the R channel (and all those between). But the speakers dont vanish, and nor should they.

One of our consistent goals with the loudspeakers we make. Done often.

I have had this experience all the time for many years now.

Some other people too.

This thread is all about it: http://www.diyaudio.com/forums/multi...om-system.html

and also this one: Stereolith Loudspeakers Question

and this one:
Stereophonic Sound from a Single Loudspeaker

and this one:
Try Ambiophonics with your speakers

and this one too:

I thought my Mar-Kel70eN disappeared pretty well. Not like the MBL 101 Extreme but they cost slightly more too. Oh, and the JBL Everest D66000 was pretty good at disappearing as well despite its size.

guests at my home always ask "where are the speakers?", earlier (when I had a "stereolit"-like speaker) they asked "where is the other speaker?"

Just to toughen up the requirements a bit, we won't count Ambiophonics and the like, and require at least, say 75%, of the treble content to come from a driver which is nominally directly facing the conventional listening postion ...

Also, no special, "doctored" recordings - has to "work" with conventional tracks ...
