Those of you who believe measurements aren't the whole story, do you have a hypothesis why that is?

what measurement will accurately tell me how well bass below 200 hz will integrate in my room.

You can buy a calibrated measurement mic (like umik-1) and run the simplest test possible to get an in-room response of your speakers. It will tell you exactly how well bass is below 200 Hz will integrate and more. (Although I believe you are talking about anechoic chamber measurements, I still wanted to write this)

Hifi tech jumped in - let's say in the last 10 years - so much that old chaps just couldn't keep up and still want to sell and use old tech for a hefty price.

Silly. You just have to have golden ears and listen to a speaker made by the same manufacturer at the store or someone else's house.
