The Z6 is an unbelievable speaker. A month after putting the Pro series in my car I got a sneak peak of these at Boston's factory in Peabody, MA and kicked myself for not waiting. They're my next audio upgrade without a doubt. They use the same Tweeter as their top of the line VRM-90 home speaker (which I own
), and they play an octave deeper then the Pros. They're definately a good value at $1000. Now match them up to one of the new Boston amps coming out and you'll have one sweet sounding system (as long as a good sub is in the mix).
