I understood you to mean that the crossover has an impact on 90% of the sound not the cost, i just question the validity of this claim. Furhermore what brand of high-end speakers use crossovers the size of amplifiers? Theil 3.7 is the same dimensions as the lowly Klipsch RF-7 and the the Wilson Sophia is not a huge speaker either. I don't doubt that Klipsch takes WAF into account with the Palladium line but so does every other high end manufacturer. The Klipschorn certainly does not attempt to be a cute speaker, does it employ the massive crossovers you speak of? What company does?
Klipsch Palladium P-39F?
Has any of you heard these yet? I believe they are available to select dealers now. I was a big fan of the Klipschorn back in the day and thought these looked interesting. I would also like to hear what others think about line.
