Yes, interesting read about Gene's experience. I found it noteworthy that even after Gene was unable to hear a difference between the two crossovers, he still uses terms such as "upgraded", "higher quality" and "higher end" in describing what should be termed simply a "modified" component if no actual audible superiority is to be implied.
It's common practice to incorporate expensive, high end parts and/or materials in order to justify the price and claim of a high end product. Skeptics will claim that limitations in the drivers, tweeters, cabinet, and/or speaker design are preventing the "better" crossover from flourishing.
It would be interesting if someone could take a "high end" speaker with "high end" crossover and replace its crossover with one using lesser materials/parts to see if it yielded any difference in sound quality.
