Speakers that disappear

You have started a popularity contest for sure but the truth is my Tyler Linbrook Signature System which are large floor standers and invisible with sound. The only thing you see hear are musical notes in suspended air all across my room. Super 3d imaging, wide deep stage, and dynamics that you feel when cranked up. Real satisfying musical listening time.

To achieve this kind of sound you need to put in the time for proper placement. The iron chef method is what i use and hands down it works.

You might want to check out this thread that Tvad started awhile back, as it is similar to your own question:

Speakers with imaging "Free of the box" Thread

As far as the best dynamic speakers I know of that disappear, first would be the Rockport Antares (one of the very best speakers ever made, IMHO - A friend owns these). The Eggleston Works Andra II also does a pretty good job of disappearing themselves, (and I own these).

I will also opine that planer type speakers, such as Quads, Apogees, etc., "generally" disappear slightly better than dynamic speakers, but only if you're in the sweet spot, which said sweet spot "generally" tends to be much smaller than dynamic speakers, IMHO. (This is one reason why I prefer dynamic speakers over planer speakers - I like to be social and listen with friends!).

My two cents worth.

"What affordable (Under 15K) speakers fit this description"

A lot, or none, depending on your competence in proper set up and choice of electronics and sources.

All it requires is a bit of knowledge, some money, and a lot of patience and flexibility (spacially and mentally).

Buying speakers which can 'disappear' is easy, but getting them to 'disappear' and produce holographic images is the real trick. See the thread re Holographic Imaging posted by Dazzdax.

Tvad is absolutely right - set them up on your front lawn for a couple of days - they are sure to disappear.
