Has anyone ever heard Danny Ritchie mention there is a fee associated with him evaluating a speaker sent to him? I have yet to hear of an evaluation fee. A speaker is measured and upgrade kit developed. From there it appears totally up to the speaker owner to buy the upgrade or not. Danny is likely not working for free, amortizing his evaluation time across X number of upgrade kits sold. Completely legit business model.
The before and after measurements are certainly in line with achieving as flat as possible FR with good horizontal and vertical FR. The after version would certainly fall in line with what Amir considers good measurements. Dennis Murphy has done the same thing, developing and selling upgrade kits for popular low priced speakers.
Seems like this whole discussion can be boiled down to Chevy vs Ford personal preference. Some prefer a Chevy and would never own a Ford, and vice versa. If you don't like products offered in the free marketplace, develop and sell your own better product.
I don't know what point you're making, or how it relates to previous comments in this thread.
Some of the things that people point out, that bother some people, is that most of the crossover "upgrades" to more expensive component parts, like upgrading the cheap resistors to more costly resistors, is a waste of money that people spend because Ritchie has them convinced that it will improve the sound quality of their speakers. Some of the component upgrades may actually be helpful, and wholesale replacement or true modifications to the crossover may be helpful in some cases, but on the whole, too much of it is just hooey. He also takes people's money in exchange for hyped power cables that don't actually do a single damned thing, and this also bothers some people. Defend him if you wish, but it is difficult to trust someone who does these things.
