Default Class D high frequency output transformer

Hello ,
I am interested in using a D class amp with a high frequency output transformer to drive ESL loadspeakers.
Is it possible ?
I have tried this with TD7480 , but it didn't work well, thought some sound was coming out.I used 1:1 turns ratio with a regular loadspeaker for testing , ~ 50 turns wound on a feritte toroid.

Regards ,
Lukas

Default Class D with O/P transformer

Not possible as the filtering on the secondary would be very difficult. Remember the voltage on the secondary is high.
