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)?

Perhaps search for a high quality USED speaker for 1/2 price when new.

Spatial Audio's speakers can compete with many at 2X the price, not so sure about 3X the price. 

There are plenty of vintage and near-vintage speakers that compete with current offerings of 3 and 4X the price, Spendor SP100s for example. 
@mapman , Map you heard the Carrera’s at CAF, correct? I bought those very ones you listened to.
