horn or line array?

You dont need to insist on speaker with plasma tweeter.

My Vaughn Cabernett II with ribbon tweeter and accuton ceramic midrange driver give also decent female voice although it falls  short of Lansche little bit.

cheapest speaker with ribbon tweeter ?

Go for plasma tweeter if you can afford.

But Altec A7 wihout passive network give nice female vocal.

Likewise, Scaena without passive network give very good female voice too.

Midrange driver of Lansche is connected without passive network like full range driver.

I hate passive network which reduces details.

but the sound of mini cymbal will be gone if without tweeter  ?  yes?

just make sure  get the information as many as posible before decide horn or line array
