Good evening,
I believe that we are loosing a little bit of sense in here. I donnot believe that there is any universal true quality test on acoustics since human behavior is THE main input. Of couse I am talking about coparing relatively equal products. I spend sometime sometime ago building the ALK-Cornwall crossovers. I sold them 15 days afterwards. That donnot means that they are bad. Some people like them some not. The same is with the Klipsch crossover, some they like them some not. The issue is your ear your amplifier and the music you hear. It reminds me this discussion also the eternal debate oil caps or hi-tech polypropylene. I got all species original oil from the Klipsch new from Jensen, Hovland and Auricaps. I tried them all. I donnot care their ECR if it s 200 2000 or 200000(I send once to AL on Hovland and one Jensen to measure them). I donnot liked the hovlands so I stick with the Jensens. Does that means that Hovlands are bad. No only there are not for my ears, same for some others.
So trying to prove that Hi-Tech approaches can achive the best recults it is not always true. One thing is measure in the bench something. Another is to put it in an apparattus. It is not the same thing.
I am of the Japanese approach; tuning the crossover and other components by ear not simulations. i did a lot of simulations in my life to believe them.
cheers
