I don't think that Volti is taking a harsh or unreasonable position in that I don't really know, how on a practical basis, when you are making more or less one off custom made products you can have a return policy. I guess, in theory, he could have a "generic" tour model...but then again, how are people going to feel about eating two way shipping costs of $500+ if they don't like them....let alone all the finger pointing that could very well occur when a 110lb speaker gets dinged, even slightly, by the shipping company
I totally understand anyone not wanting to take the risk of buying an expensive 100lbs speaker with not hearing at home first...and just because it sounds good in someone else's house, guarantees nothing about how it will sound in your house.
