Most “disappeared” speakers.

Hello nasaman,

     I agree with shkong78 that the new Magnepan LRS planar-dynamic panel speakers are an excellent choice.  These can definitely do the disappearing act but have a few requirements to do so; they need to be pulled out a minimum of about 3' from the wall behind them, need about 100 watts or more for optimum vanishing and are limited in bass response.
      Here's a youtube review:

     You have a healthy budget which results in many good options.  One excellent option would be to combine these $650/pr Magnepan panels with a $2,800 4-sub Audio Kinesis Swarm distributed bass array (dba) system for a total cost of $3,450 that I know would provide a very high quality, full-range and very unique version of a disappearing speaker system.  Here's a link to an Absolute Sound review of the Audio Kinesis Swarm dba system:

     However, your room would also need to have adequate space to accommodate 4  1'Wx1'Dx 2'H subs positioned around its perimeter.

     Another good option for disappearing speakers that's a bit simpler, and may better meet your needs,  would be a new or used pair of one of the current or former Magnepan speakers that are a bit larger and have more bass extension.  Good candidates would be the 1.6, 1.7i, 3.6, 3.7i, 20.1.  Remember,  all Magnepan speakers are dipoles, however, meaning sound is emitted from the front and back of the planar-magnetic panels and they all require at least a 3' space between the back of the panel and the wall behind.
     Could you state the size of your room and the amp you plan on using?

Costco sells this thing you plug into the outlet. Then you plug your lamp into the thing. When you press the remote the light goes out. Speakers, everything, whole system disappears.

Vandersteen 2Ce Sig disappears about as well as any $peaker, even with the lights on and the signal in one channel.

I haven't heard these in a while, but I have a soft spot for wide-baffle speakers. 

The Sonus Faber Stradivari are excellent examples. While small 2-ways often disappear if properly designed and out in the room, the wide baffle speakers have their own benefits and ease of integration, and are much more location friendly. Plus, I think they're gorgeous.

+1 to @douglas_schroeder  's posts.

Whichever one I want.

....the effect of sensing the speakers have "disappeared" happens when they are setup properly

Almost any speaker can be made to 'disappear' ... this is also about your system (not solely the speaker).

i had a pair of crappy advent legacys get stolen from the garage rig.. those are so diasappeared i cannot hear them anymore

Coherency between drivers matters to avoid image shift of notes that span the crossover region.  Most speakers that get this right will disappear if placed properly with respect to the listening position.  The most impressive demonstration of this for me was with a pair of Harbeth M 40.2.  You could not detect a single note, artifact or sound localized to the speaker.  Every sound came from behind them as if on a 3-D virtual sound stage.  The key is to have lots of room behind the speakers, e.g. 5-6 feet if possible. 

BTW, that is not to say the soundstage characteristics of each will be the same. But, the effect of sensing the speakers have "disappeared" happens when they are setup properly. If you don't get that sense, then you likely have not set them up properly. YMMV 

Whichever one I want.

That is not a flippant answer. If you know what you are doing any type of speaker can do this.

I do not recommend buying a set of speakers based on the perception that one will magically do this "disappearing" act better than another. If anyone is trying to sell you a speaker that way, run the opposite direction, because they are B.S.ing you or ignorant. :)

Buy the speaker based on your loving the overall characteristics of the sound. Setup and selection of components and cables will take care of the rest. 

Charney Audio Companion Horns disappear with SS and tube gear. Soundstage is wide, high, and deep with superior tonal balance.

You can try out Magnepan LRS with generous 60 days return policy.

Planar speakers are known for disappearing act.

I also pulled the trigger for LRS although I have nice dynamic speakers.

It's as much about the room and speaker placement than the speakers - maybe more.

Easy. MBL speakers.
I got my 121s for a steal years ago, but that was because they were damaged in shipping to someone else so they were sold cheap.
Nothing disappears/soundstages like the MBLs that I've heard.
Then again, it's rare to find them that cheap. 

Otherwise, I agree with george, Audio Physic speakers are reliable for a disappearing act (one of my other favorite brands). 

The most "full range" dynamic speaker that do the disappearing act would have to be Audio Physics, and then also most ESL’s and Planers.

Cheers George
