OK, assuming you're right there's still the woofer diaphragm assembly and its potential impact on performance WRT Fs, Vas, Qts that has to be considered. For all we know they may need a custom mix n' match assembly to perform like a mini-604 and if some were made, then what brand(s) and at what level of specs accuracy? Too many variables for me to not maintain a potentially 'harsh' judgment of realistic net worth.
