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)?

Vandersteens - all of them. I honestly prefer the 2s to the 3s, even though the 3s are more accurate, and the 2s with a pair of the subs over the 5s, for the same reason.

2s are a bargain classic, but I like the later larger models which have better tweeters as well as what is basically a subwoofer built in. My 4As have stood up very well and the 5s are just a refinement of them, in a sense, and should be available used now for a decent price (c. $7K)
Check out Seaton Sound and JTR Speakers.  Both offer extremely high performance speakers and subs at prices that are a tremendous value compared to many of the main-stream and boutique companies. 
Absolutely thrilled with the performance of my Tekton Double impact monitors, giant killers for sure
