Ok, so the M80 are here and sound great. Is there a break in time

There shouldn't be, but technically the T/S parameters can shift if you push them hard enough to where you are heating the voice coil. But it is more of a temporary thing once the signal is not present anymore.

It's really no big deal. However long it takes you to enjoy a pint or two while listening to some tunes on your new speakers. That's "break-in".

Actually its about 6 months. After that you will find that the permagrin starts to wear off, but the speakers still sound amazing. Oh, wait, you are talking about the speakers. carry on...

Troy, drivers cycle hundreds or thousands of times per second. Any permanent break-in occurs in a matter of seconds and probably took place during testing at the factory. Enjoy.

Your speakers are already broke when you get them.

Has Axiom confirmed a test being run on each speaker before it leaves?
It would be cool to hear the testing method, wattage, lenght of time etc.

I am not aware of any article that Axiom has produced on speaker testing before it leaves the factory but many times on the forum Axiom staff has mentioned each speaker is checked for operation before leaving the factory.

I don't imagine it is an overly exhaustive test, most likely simply hooked up, checked for sound/clarity from each driver and then sent on its way to the consumer.

The extensive testing is done long before the speaker is sold to the consumer with each new version/design change.

I seem to remember something about it being Slayer, but I'm not sure.

I am not sure why some speaker companies insist there is a break-in time, I, personally, think it is all nonsense. I believe it has been said many times before, it is your EARS that are "breaking in", not the speakers.
