Axiom Home Page Forums General Discussion Technical Questions Axiom's view on speaker break-in?

. I'll sleep on it. I don't want to believe what I heard.

Agreed rrlev.

Mojo…..so? Spill the beans! Or nuts as it were….

Alright. I set up a test. I had not listened to my living room M5OW for 4 weeks. When I turned them on, they sounded like shite. Seven minutes later, they sounded absolutely wonderful.

Well that’s not that nuts really. That’s how my joints feel sometimes. Takes a few minutes to warm up before feeling good. Woofers could be the same way.

I’ve certainly experienced in my old living room, very tangibly, the sound improve significantly over a 45 minute period. I chalked it up to either the amp warming up or the room warming up over all, with the wood stove quickly warming the house in the winter. I’ve always wondered if humidity in room would make a difference that I could hear. I’m just speculating, haven’t done any real research or thinking on it.

Sometimes I feel like the room ambiance plays a big role tool. I recall a listening too some mellow jazz acoustic guitar, lights glowing and warm. And room very wood stove warm at night in winter, sounded lush and intimate. But that’s probably more about emotional ambiance than pure listening. But if it creates the effect that affects me, then I say that’s awesome!

You’re not crazy Mojo…

Like I've said in the past when I had v2, ambient temperature changes sure made a difference to how music sounded. In this case, ambient temperature was not a factor. It's all Andrew's problem now. As Chief Engineer of Axiom, he has to be able to explain these phenomena or he simply is not going to get into engineer's heaven.

Damn, I want a wood stove too. Love wood and love burning it.

Yeah i remember you saying that about ambient temperature and ferro fluids. It cant be that crazy to think that if the woofers sat for a while, 4 weeks in your case, that it would take some time for things to loosen up perhaps and become more pliable. That or your alchoholic libation kicked in...

Bottoms up!

Yeah, my M5s like it hot. Like basted lamb shanks.

My amps sound better after warmup too.

Amir actually had to remeasure a genelec setup and a few degrees farenheit changed measurements. He noted the woofer behavior changed and hit a few cycles lower and smoother.

Basted lamb shanks...lol. I don't follow Amir but cool he was able to show a difference. Magnitude response is one half of the behavior. Phase response may be another thing that matters in this break-in/warm-up quagmire.

Incidentally, the Mirage OM-5 developed by Andrew, states:

We strongly advise that you resist the temptation to play the OM series to their full capabilities or experiment with critical placement and listening until they have been properly broken in. This process should last approximately 50 to 100 hours of music playback.This can be done efficiently and effectively by putting your compact disc player onRepeat mode, while playing a CD with a wide dynamic range at normal listening levels.

The Thiele Small Parameters change during break in and over time. Measurable.
