Axiom's view on speaker break-in?

I read lots of opposing opinions on the amount of use a speaker needs to be considered 'broken in'. Opinions range from no break-in required at all (ie good right out of the box) to hundreds of hours required.

I'd like to hear from the Axiom folks who engineered these speakers. What's the Axiom position on the break-in period? After how much initial use should we expect to hear the permanent Axiom's sound?
Thanks,
Peter C

For the purpose of all of our testing we break in the components for 2 hours. This is lots of time to get consistent measurements from then forward from the components. I have heard of people going to hundreds of hours of break-in, which would seam to be a bit overkill.

Yes it is (interesting)! I've never seen an opinion from someone with credentials; most of the time they hem and haw. I will now pay keen attention around the 2 hour mark. (If I ever get another good speaker.)

I've reported that some of mine arrived broken in and others did not. Some required a few hours and others tens of hours. I've also reported that I was noticing significant "voicing" changes with temperature changes in my v2. I don't hear that in any v4.

Interestingly enough, I pointed out to Ian that when Soundstage measured the M5, they found the impedance curve to be quite different up top from what Axiom published. He surmised that could be the viscosity of the ferrofluid. They may have tested it when the speaker came in from the cold. That could explain why I was hearing differences in the v2. The v2 and v4 tweeter designs are of course different.

More interesting stuff on break-in. Andrew broke them in at the Mirage factory and the reviewer had to break them in again.

As at November 14, 2017, Klipsch never tested any of its speaker components or speaker systems prior to shipping. The proof is in the first sentence of the second paragraph.

Mojo, I do not take that statement as fact … it’s written by marketing not engineering …
I’m sure the components went though some sort of testing before assembly and after. Break-in on the other hand …. I’m not as sure about …

Yeah, I know. smile

I'd tell you my latest experience with break-in but you'd all think I'm nuttier than an Oh Henry! bar.
