Time coherence - how important and what speakers?

If there were a such thing as the best way to design a speaker, they would all be the same.To each his own,end of story!

Roy, my post wasn't towards you!I try not to generalize the design of speakers.I see some that do instead of allowing their ears to lead the way.If it sounds right than that's what I look at.Not whether it has ports or not.My hats off to all of you designers for bringing that magic to my ears and others.This is one of the few hobbies that is truly personal.Each man has his favorite and the one he prefers.Talking about a man's gear is just about like talking about his wife.Ha Ha HA Best regards
