l'acoustics are also particular on who they sell to.
in general, the closed system types make it simpler to not fuck up processing settings.
nexo, d&b, l'acoustic, meyer, duran audio, etc - the speakers are by default active or require a proprietary processor/processor-amp to properly function, and the user cant then fuck up xover settings, etc.
of course, flying and aiing is a different story. line arrays require aiming software, and some, like duran and martin audio new series, require venue specific information to finish processing. The high price tag keeps many of the idiots at bay, but sophisticated looking products with lower entry costs keep the hacks at work.
