I work at an Audison/Hertz dealer and my coworker's Tahoe has the Voce 3 ways in the front doors and 5.25" coax in the rear. They are powered by an LRx 5.1k which gets its signal from a Kenwood DNX9980HD. It is somewhat of a frankenstein in that because of the limitations of the current (temporary) set up (and as a previous person stated, the three way set has passive for only mid/tweet) we used some Morel MX33 from their Elate 3 way set (approaches the $2k price). They have the same recommended crossover points as the Voce speakers and we have sold a few sets this way.
They sound great!! Not exactly what I personally tend to lean more towards (which is the Morel stuff), but if you are looking for great sound quality and prefer a brighter tweeter, this is a great set for you. I would call them Focal-ish in their high frequency reproduction, meaning a bit on the bright side. I have found that this is what most consumers want, so it works out great from that standpoint. I personally am pretty sensitive to high frequency so again lean towards the less pronounced Morel line (some would say "dull", but just right for me). I'm sure I could attenuate the tweet down a bit and I'd love them, but they aren't mine and like I said before most people like the brighter tweet.
In conclusion, get them!! I'm sure you won't be disappointed as long as you know what you are doing with the crossover portion of it.
