Tvad is absolutely right - set them up on your front lawn for a couple of days - they are sure to disappear.
Speakers that disappear
Here is a description of a speaker found in TAS, the recommended components issue:
"... simply don't sound like other speakers. The Xes are tonally neutral and nearly sonically invisible; voices and instruments don't seem to be coming from drivers in frames or boxes. Instead they hang in space, free-standing objects that are so three-dimensionally "there" that listening to *them* is like going to a play, where listening to other speakers is like going to the movies."
What affordable(under $15k) speakers fit this description?
