this thread was on fremont's or I am wrong?
LOL - quite right.
JK,
I will check that Clapton unplugged song tonight first on my speakers ( which tend to be polite or rolled off in the highs - because they are silk dome tweets ) and then on my trusty AKG 240's (much more linear). Most ot the important cymbals stuff is around 12 Khz but there may be some "air" higher up. Bear in mind I can't hear above 15.5 Khz anyway - those days are long gone with age - so if I report that it sounds muted then I am not sure if that means much!
As for what might cause it to sound muted - I have no idea - in general I would think that a silk dome should almost always sound muted or "polite" relative to a metal one. Generally a more "etched" or exciting sound is the way I describe how light weight cones tend to sound but this is a generalization.
