[Harp-L] Speaker overtones or Ghost notes

["mike wesolowski" <mwesolowski@xxxxxxxxxxxx>]

Recently  I was in the "Tone Lounge" where we've got a Demo speaker cabinet with 33 different speakers.  14 12s--14 10s and 5 8s.  I was demoing some brand new Eminence 12' Governors and when I hit a certain note on the harp, I'd hear a "ghost note' or some sort of strange overtone.  Kinda sounded like it was 2 octaves up from the note I was playing.  Strange.   I've got one of these speakers in a cab that I use along with a reissue P10Q and have never heard that overtone with my speaker.We contacted the guys at Eminence and he told us that after the speaker was broken in that the overtone would most likely go away.  I personally have never experienced this before. And............it seemed like it was on 12" speakers that were doing it. None of the 10s did it. I tried the Governors with guitar and didn't seem to notice it happening.  Douple strange.
So........what we're going to do is building a seperate speaker cab specificly for breaking in speakers.  I think that we'll throw the new speakers in and keep a load on them for X amount of time.  I have since heard that if you break in the reissue Jensens, that they'll sound identicle to the old Jensens we all know and love in our old vintage Fenders and such.
Has anyone else here experienced what I'm talking about?   If so..........I'd love to hear your input.
