cheapest speaker made in the last 10 year that can beat any speaker made before 1970?

I wouldn’t own any speaker that is over 10 years old. I had some of the top of the line speakers for their day (50 years ago and newer) and wouldn’t even think about owning any of them now.

There have been many advancements in speakers in the last decade or so, and some of those are: 

Beryllium tweeters 

Diamond tweeters

AMT midrange/tweeter enhancements (I did own some speakers in the 70’s and 80’s with the amt speaker and todays versions are better)

time aligned speakers

cabinet construction and materials

even the newer concentric/coaxial speakers of today are much better than the older versions, if you like those kind of speakers 

crossover designs are much better today than the older designs, the parts themselves are better today

It's gonna take a lot to beat a set of Quad ESLs or many other high end speakers of yesterday, if you even can.

@bruce19 he  show up just only to answer my question ,, and i  am glad he did

@p05129  it seem only you said that today technology can beat speaker before 1970
