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

Before 1970? That would be 1969.  The year of Woodstock (that I didn't visit until 2019).  And, the Texas International Music Festival that I DID visit in 1969 (skinny dipping was highlight).

I remember how important Linear Air Spring tweeters were in my life.  As well as (classic) rock delivered via Assymetrical Charged Coupled Detector Tuner.  And, the precision and tactile feel of the Sonic Holography Autocorrelation Preamplier.

Everything else is a bit fuzzy.

Vitntage speakers with disintegrated foam surrounds are a bit "compromised" in the low end.

asvjerry, you poor thing. My mother taught deaf children to dance...by feeling the beat through their feet as she pounded on the floor. There is music and fun in the world, and all you have to do is listen however you can.

I guess there is such a thing as a stupid question after all.

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
