Is break in quicker with Planars and Stats?

Norton - with Magnepans at least you can take a Radio Shack SPL meter and measure the falloff at a certain level of input in bass, and 3 months later the response curve is different. I don't know as much about cone speakers and personal experience with breakin but I can say scientifically that the Maggie 3.6s sound *very* different on 1st day and 3 months later. And, as I said, I can verify this with instruments and graphs.

and that is of use how Norton?

Speaker break in will be the same because what is being broken in is the listener not the speaker. Neither the transducers nor, in particular, the crossover components should change after the first 2 seconds of use, unless they have been just taken out of a freezing semi - and even then once they come up to room temperature there should not be any further changes. I suspect that the idea of break in arose from vendors who displayed speakers in an acoustically well designed room and driven by high end amplifiers, likely playing music selected by the sale staff. When the person gets them home into a different acoustic environment with a lower grad amp and music not optimized for display purposes, he or she is disapointed - hence - the break in theory proffered by the sellers. It works because after a while a lot of people will get used to the sound, associate it with leisure time etc and believe that their speakers have indeed broken in. What makes people willing to do this - most people don't like to think they got a bad deal or did not get what they thought they were getting. Fortunately, there are very good respectable companies making very good products - so you will probably be very happy right off the bat.

It's a shame that the information Musicnoise typed out gets run at Audiogon. Invariably there will be newbees that believe what he said and possibly sell a good pair of speakers before ever knowing what they really sound like.

Lightminer is correct:

Both scientifically and by common sense and old fashioned listening to music.

Albert...I must respectfully disagree that we should not be allowed to see the opinion of Musicnoise. I would tend to side with you in this debate, but let's not get carried away. I have found myself on several extended business trips "getting used to" the horrible sound of my laptop. There is something to be said for our ability to adjust, and cope with, less than ideal sound.
