Here is how I look at it.
Doubling the number of drivers (in and of itself) increases the driver sensitivity by 3db.
Now take into account that when the drivers are wired in parallel then the impedance is halved.
With a transistor amplifier (at least in theory) the output power will double when the load impedance is halved.
So with twice an many drivers (wired in parallel) the total increase in system sensitivity is 6db.
To say all of that a different way,
When you double the number of drivers (from one to two) it increases the sensitivity by 6db.
BUT if you only provide one watt the net increase is only 3db because each driver is only getting 1/2 watt.
