Driver breakin period, what’s the science?

Heavy, high excursion butyl rubber surrounds, and stiff spiders (springs), they take a while to loosen up. To sound clean and go DEEP, 50-100 hours (over night on a tone generator)

I have GR servos. LOL took a couple of hours to hear them and all night to loosen up enough to hear well.. Weirdest thing I ever seen.. Like magic. I though they were broke. They were moving but, no sound. I think it had to do with the correction side of the driver, and the servo amps.

Lighter foams and springs, less time. 20-50 hours..

I’ve seen teflons caps in XO take a 200-300 hours too. The drivers were broke in long before the caps were.. Sound wonkie as all get out.. for a while.. Ear bleeding stuff, mercy.

A guy named Mike Samra, red sock green sock guy. Told me that teflon caps break in because of the DC, yet the speaker's VC would fry with it.. 

If it takes DC to break in a teflon cap, I still haven't figured how they breakin, in an XO, but they do. They sound bad (TRT) expensive caps too. Very harsh, highs will blister your ears, mids are veiled. They didn't effect the bass because there is no caps in a 6db first order low pass. But a bit boated because everything else was all out of whack and very thin. Thank goodness for Lpads and tone control.. It took 200 hours before my tone controls were back to flat, and Lpads at 11-12:00.

4 pairs all the same...  Years on a center speaker, because I don't use surround.. That one really cracked me up.. Any one need a LCR VMPS neo 8 planar center speaker. Just broke in after 13 years NOW... LOL

Some stuff does take a LOT of time.. just sayin'

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..
