Hi There,
I seem to show more ignorance with each response I give, haha. I just wanted to clarify what this squeal sound is that I'm hearing on certain speakers. The high pitched squeal (almost like a dog whistle) is only noticeable on the Swell 8' and 4' flutes and in the middle C octave and the octave above mostly. When I switch that channel to other speakers it goes away. The speakers I have hooked up to that at the moment are one set of Rodgers bi-speakers and I also had a set of Allen full range speakers that I got used (perhaps they had been blown?) Anyway, this squeal I isolated to coming out of the Allen tweeters, (on both speakers) so I have just disconnected them and am wanting to replace them with other speakers that don't have the high squeal. Hopefully, my description here makes the problem more clear. Any suggestions?
John
