I personally believe there is some break in and here is why. I replaced a woofer in my sons sub just before Christmas. After we installed it, it barely produced any bass, no setting had been changed. Within a few days the bass output was better than it had ever been. Same thing with my Yamaha powered sub that I replaced the driver in. When the speakers are designed they have many hours on them during design and crossover tweaking. Before they leave the factory they are fed a brief sine wave through each driver and monitored by a computer (axiom uses LMS ) program to test they are working correctly. So prior to you hooking them up they are fresh and stiff right out of the box. There is a reason why new surrounds are available. That's my thoughts take em or leave em smile

Yes, speaker "break-in", to the extent that it's sometimes claimed to exist is largely nonsense. Periods of use requiring weeks or even months are promoted occasionally and it's been said that "break-in was invented so that we couldn't return anything"! An initial permanent break-in which would take no more than a minute or so(and often would take place in factory testing before being shipped)would show a measurable "loosening" of the driver. Every time a speaker is turned off it partially reverts over a period toward its unused state, but this immediately returns to the "broken-in" state a second or so after being turned on again.

Dr. Toole and others point out the lack of any long term audible changes(in blind listening tests)which can be observed. This may be fortunate. I now have about 30,000 hours on my M22s and if some long-term changes were occurring they certainly would have reached the optimum point long ago and now would be well into a period of deteriorating performance. Instead they continue to sound identically excellent as they did when I fired them up with "The Planets" when first received.

Randy, it's about 7-8 hours a day of classical music over the past 12 years.

Edit: Rob, good to see you back again!

I noticed a definite difference around 20hrs with my M80 v3. It probably relates more to the fact I felt safe turning them up at that time.
I haven't received my shipping notice yet for the HP's.
Hopefully someone else will confirm.

I will take real world experience every time. Watch this Video made by Andrew Welker ,and a 3.54 you will hear Andrew explain the frequency sweep used, and the sweep does not move the drivers appreciably. Your response, no matter how eloquent,implies that people who hear a difference are idiots and that is not the case.

It seems I always leave something out of my posts.
To elaborate on my last post it was the tweeters that seemed to mellow out at approximately 20 hours and at that time I got a little more carefree because of how nice they sounded.

Thank you, John. Good to see your sage advice. Not to hijack this thread, (just mentioning this is probably a bad idea) I'll start a new one (thread) in a couple of weeks asking advice on the latest AV Receivers.

Now that was a series of responses! Thanks to all, the speakers are approximately 4 hours away from delivery (yes, the OCD kicked in and I tracked them). I will see if I notice any changes over the time from when I initially use them. Unless Axiom does another worthwhile upgrade, I will be listening to these, however they sound, pre and post "break-in".
