Is it me, or do the ck61's just sound better than the 63's?! I was so excited to get the ck63's, but for most every application I have used them both for (inside and out) the 61's offer much broader sound quality without over emphasizing the crowd. The 63's sound a bit flat to me. I have yet to find an application that I prefer the 63's for. Although, I never taper farther than 65ft away from stage.
I'll try them tonight in a Mid-sized venue that has typically boomy features. Hopefully they will justify their price tag...
Just venting
