Driver breakin period, what’s the science?

Like I said, and a LOT of folks using fancy caps, they make noises that are hard to explain. Measure? Who would want to.. I’ve heard teflons break in a couple of times. After that, I put mine face to face, covered them with heavy moving blankets in the shop and let them run 4-5 days at 60 70 DB. They use to run tone generators on speakers for a week before shows.. It’s usually the last days of the shows the systems sound the best.. It has more to do with settling and breaking in.

Danny at GR is a master of taking advantage of all that.. Big curtain guy too..

I loved the VMPS CES show stoppers.. Danny never had good word for VMPS, other than. I like to help Brians customers.. Nothing has changed.. Still fixing 100 year old companies XO, saying "I fixed them"
Hell I could fix anybody STUFF after the fact.. "BURNED IN" guy.. I quit listening right after that.. They break in, good Lord. I bet he works on his motor, and changes the oil. ENGINE. Words count... 

He was quit the SA in his early years with other folks speakers.. Still is taking on JBL and a few others.. LOL Yea... I own his servos, pretty good stuff. BUT I sold his redesigned 123s, What a pile of crap, they were.. OB piles of junk...Could never get them right.. Looks, They were nice looking... Good for parts...

My RM40, 30, RM2 and Elixirs, whip the pants off of them. Actually a lot of his earlier stuff.. His newer designs Danny is hard to beat for the money.. BUT it can be... Nothing I’ve HEARD on these forums though..

But I’ve never hear a Magico, probably never will..Wilson same way, no interest. Watt Puppies I’ve heard. Give it to me, maybe. Pay for them NEVER... Danny he insulted my friend Brian C to many times... AFTER he was dead.
Yea, about that guy.. LOL He may live in Texas, but he ain't no Texan..

In some speakers and electronics the difference in break in can be dramatic but in others there is only a slight change my hope is that the drivers are real good and the former will occur for you but what i can say is that letting your system warm up with background music for an hour or two will really help before you seriously listen every time you play your system.

I doubt there is very much to it. It is mostly your ears getting used to the new speaker. Yes, there may be some break in happening like anything else, but no where near as long as some suggest.

Are you using ported speakers? Is that how the spiders enter the enclosure? My cabinets are sealed enclosure.  HVAC

Relative output of your driver's did not change more than a fraction of a db after the first few hours. The crossover points may have changed a very small amount.

Back in the day, we broke in studio woofers with a Crown DC-300 input pad plugged into the wall. Played 60Hz for at least 24 hours before swapping. Never measured for any level difference, but sonically, un-buzzed woofers sounded flat and lifeless. Old woofers were sent back for reconing. Mid/Tweet drivers could be reconed on site. Techs used to hang shredded diaphragms on the wall marked with the band / musician who blew them.

Note that the above speakers were abused and suffered mechanical failure. 

To the long break-in crowd:
Do you log listening room parameters Temperature, Pressure, Humidity, Line Voltage? see  ieLogical WinterBlues
How accurate is your level control? [Have you ever verified it?]
Have you verified the amp is operating at EXACTLY the same BIAS point?

My 35 year old speakers break-in CONTINOUSLY due to the above. The CBLF is infallible and contributes not...
