For all the engineering efforts, JBL/Crown could go a little farther on the connector side. In a perfect world you set it and done but... even in the pro world that's the dream, not the reality. They could learn something from some of the audio connector companies that have made hand tightening into wrench tight quality. That or just use Speakons... I guess on the flip side you end up with some nice looking cables!
That setup is heaven for the nerd that loves to fiddle with endless little tweaks of settings.
