Yeah, everything I listened to came off as a little bit obnoxious with the top lifted.

I also used The Edge to determine f3 and that resulted in a much lower f3, 240Hz from The Edge vs. 442Hz using Rod Elliott's formula. I built that 240Hz f3 circuit, but after a few minutes of listening it was obvious that the higher 442Hz f3 resulted in an overall sound that I liked better. When I have time I'll hook up the laptop and do measurements of the drivers in the enclosures to see if what I'm hearing matches up with empirical data. What I'm hearing now sounds pretty good for the $ I've spent.
