I found that the higher quality gear you go with, the less difference and more subtle the cross-over change becomes. It's all really subjective but someone who does the cross-overs for money will be even more less objective about them. I had my RF-7's crossovers upgraded and what I did notice, is that it tampered with the dead-on center of the vocals that I so highly liked. It widened the vocals that wasn't as realistic as the dead-center vocals like Klipsch intended it for..... as if the singer was right there in front of you in that spot. I had to trade my crossovers with another RF-7 owner to get the well-made Klipsch crossover sound back that I so enjoy. The crossover change reminded me of the wide button on some amps, making the sound wider but taking away in other areas to do so. It wasn't my cup of tea.
