That must be killer! I've been wondering myself about 2 woofs and a piezo tweet for a center channel; I've been using phantom center. Would a better dispersion for the dialogue perhaps involve 2 tweets or are the woofers handling enough of the range? I have a chart for musical instruments and singing voice Hz but not dialogue. Can 2 or 3 people sit in a row and not have voices coming from the wrong places? BTW, one of the worst movies but an amazing you-are-there soundtrack is XXX with that Diesel guy. My daughters dragged me to see it (oooh, he's so gorgeous)and then laughed all the way thru! There is however the best snowboard stunt scene in history.
