You know, that's right. Completely missed that on first read. If what you're hearing sounds like somewhere around "F" above middle "C", you're talking about midrange frequencies. This is well within the realm of the midwoofer in the four π loudspeaker. The crossover band is about two octaves above that.
It is possible that what you're hearing is a problem in the overtones from voices and instruments hitting notes in that range. That makes sense, and so it could still be something in the compression driver. I think probably if you brought it up, you already noticed something funny about the tweeter. But the DE250 is a pretty good driver when working properly. I'd like to test it or swap it with a known good unit and see.
At any rate, I think we should re-examine this and troubleshoot the problem. Might be a damaged part, and we can easily recone drivers or replace components after we find out which one is to blame.
