In Reply to: What makes a driver High Efficiency? posted by catbert242000@yahoo.com on May 27, 2023 at 18:14:46:
You specifically ask about drivers, so ignoring the enclosure design (very important in its own right), the main influence on sensitivity of a driver is its magnet. A small current passing through the voice coil will move further and faster if it's contained within a powerful magnet. The closer to the centre of magnetic influence the better.
The further and faster the coil moves, the greater its sensitivity as the resultant sound vibrations that reach your ears will be louder for a given coil current.
Someone will almost certainly shoot down this explanation, but there we go!
