Post Subject: Singer's formantPosted by Antonio J. on: 12/2/2005
I believe that those "allien sounds" are an enhancement of the frequencies comprised in what is called the singer's formant, which is the area of the third formant when opera singers sing vowels. That area is in the range of 3.5 to 5.5 KHz and is a special resonant characteristic that opera singers learn to develope to be able to overcome the orchestra sound. Since you seem to notice those "allien sounds" when they sing high pitch notes, that would place that ringing more in the 4.5 to 5.5 KHz area, which more or less matches the troublesome response zone of the Lowther and Fostex speakers. Were I right, then you'd have to look for other drivers for the midrange horn, or maybe looking for another solution which allowed you to control better those cones response in that area.
