Most “disappeared” speakers.

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.

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?

Ohm Sound Cylinders will embarrass all the touted, expensive box speakers! Expansive, room-filling 3-D sound. Beats Magneplanars! An astonishing speaker - I have a pair! Sadly not given any love from the snob-appeal crowd. Maybe if they came in a black-chrome finish and sold for $50K the high-rollers would covet them!

I agree with br3098 and Douglas Schroeder. Attention to details, such as proper room set up, and any speaker can do a disappearing act. 

+1 (again) to all those commenting on setup/placement.
