Instead of driving a speaker with active crossover I am thinking to drive it passive.
Say your tweeter sensitivity is 93db and your mid is around 88db
Would applying a passive audio transformer at the end of the mid boost the sensitivity of mid to match tweeter without affecting the total system response
Is this the same methods as sony ta d900 but a passive version ?

A transformer could increase Voltage sensitivity by in the end drawing more current from the amp.
I'd go for the opposite option - decrease the sensitivity of the tweeter with a step-down trafo. The transformer needed will be smaller, lighter, cheaper when only tasked with passing tweeter frequencies - a ferrite cored one will work fine.
BIG problem is that "boosted" driver impednce will sink into crazy impossible to drive low value.
*Only* speaker where it´s worth doing (and is actually done) is when boosting Piezo tweeters , becuse you *start* with a very high impedance, 25 ohm to 1k depending on frequency.
