Classical singers often prefer a much more lowered larynx than popular singers. The twanged epiglottic funnel combined with a lowered larynx is an essential part of the ideal sound colour in classical singing partly because classical singers often sing acoustically (i.e. without electronic amplification).
Without this twang it would be difficult to reach the back row of a concert hall or a theatre.
Popular singers can also benefit from using their twang if they sing without a microphone. However, they have to be aware that a very twanged and loud tone without metal and with a much lowered larynx does not sound good through a microphone held close to the mouth.
