Best 2-way as in.. Biggest-Baddest-Loudest?
How about a definite contender for "Best 2-way that can compete with a big bad three way for farfield use?" (seeing as a three ways main advantage over a two way is broad even dispersion and generally a higher acoustical ouput - granted it comes with the disadvantage of an additional x-over)
This type design lives on without the Dolly Parton look. And yes - something like this is very big and very bad - with a transient response like a panel and ability to play at a max peak of 136 db SPL - there is very little out there that will play percussion as realistically as this will.
Anyway I'd like to stay away from "best" - for sure a 2 way is better in most nearfield applications and a bigger three way is generally better in most farfield applications (with noted certain exceptions in either direction)
