The first speakers I built in 1968 used the Wharfedale 8" RS/DD "full range driver. I was super impressed but that was because the best I had heard before that were the door speakers in my parents' radiogram which were certainly smaller "full range " drivers themselves. I wasn't into hifi then, just listening to music and recording.
A couple of years later, with a lot of avid reading of hifi news and wireless world etc. under my belt, I built KEFkit 3s. There were basically the baffle panel of their current Concerto sold with no cabinet.The units were the T27 tweerer, B110 mid (the drivers still being made btw) and B139 bass. I built the biggest volume cabinet they recommended. At 20 years old anything with more bass was more better.
They were obviously more even, wider band and less coloured but lacked a bit of the punch of the old ones, which later I realised was probably created by their resonances.
There are measurements on the net of the too-expensive-for-me super version

I know nowt about any of the others, but these are quite interesting reads for anybody into the history of speakers.
Not pretty plots by modern standards
