No I haven't. I'd say so
Thing is, IIRC there's no reason that crossover can't be in the power amp, it's so long as it's before the power stage, not after. I think
Honestly, it's not something you should be worrying about, just keep it cheaper and go passive
Hertz mlk 165's aren't cheap. Then again, they're not that expensive either, especially from what i've seen if you go with an active configuration.
I was considering the audison voce's as they're also apparently warm and very similar/the replacement for the mlks. Try them!!!

Also bear in mind, if you're not installing this yourself, it makes no sense to buy the parts. Get them to install and supply parts and you'll get discounts which makes it cheaper.
