High value, giant killer speakers?

What speakers have you heard at any price did you find are fairly priced or a great deal and competed with offerings much more expensive (2x, 3x, 4x etc)? 
@kenjit the dealers all get together and price fix??

To answer the OP question I was really impressed with VOXATIV, specifically the Hagen model.  For people in smaller spaces, or want a less pronounced visual system, - I was really impressed.  
At the less expensive (not inexpensive) Endeavor  E3 or E5, more expensive is Von Schweikert VR55 Aktives which are better than many at twice the price. Key with speakers and much other equipment is to agree with the designer's ear that you like what they like in terms of musical priorities. Also I tend to prefer designers with decades of experience to hone their craft
