Hi Wayne:
I was browsing your measurements folder and was a little surprised by the way the slope of the Pi Seven declines as frequency increases, and by the rapid rolloff of the tweeter at about 15KHz.

Can you explain the reasons? I'm just trying to understand the likely sound prior to making the commitment to build, and I have been under the impression that generally speaking one aims for a frequency response that is roughly flat to 20KHz, and that some people are even aiming for much higher frequencies with supertweeters.

Thanks,
tim
