5/14 2 way speakers.... does a guy really need to leave his car
playing music for 24 hours before you can crank it up??? (thats what a
car audio salesman told me)

whats the worst that could happen if you cranked it up after 1 hour of
playing music at medium volume level??

A salesmen actually told you to leave your car running for 24 hours? How
****ing ridiculous.

Crank up your tunes all you want. You will be fine.

The concept of "breaking in" speakers is pretty big with the home
audio crowd as well. There's a poster over at rec.audio.high-end that
used to swear that brand-new speakers sounded different after he had
been playing them at home for about a month. He noticed this with
several sets of new speakers. Then one day, he bought a pair of
speakers that had been demo units in the showroom and already had
several hundred hours of playing time on them when he bought them.
Sure enough, after he had them in his home for about a month, they
sounded "different" as well. So he figured out that they didn't
really sound different after being "broken in", his ears were just
used to the way they sounded after a month or so.

The long and short of it is that you should be able to play new
speakers right out of the box without having to worry about any kind
of "break-in" procedure.

No. Not just no, but hell no. Break-in is usually only even recommended
for large drivers, and even then people with experience in the biz will
tell you it is wholly unnecessary.

Lemme guess... bought 'em at Circuit City or Best Buy...

Let me ask you this, what will you break-in on a speaker? The mechanical
part that's moving doesn't even touch the other parts. Which is to say,
the
coil doesn't touch the magnet so there's nothing to break in. The rest is
electrical. Tune up your system correctly, and blast it all you want.

The break-in crowd claims it's the suspension that needs breaking-in. Like
stretching, or some such nonsense. Others claim that it's a matter of
heating up the voice coil to bake away crap, or something.

It's different on a car engine where all that parts are touching each other
and they need some time to "fit" together well. That's not the case with
speakers, since there's nothing to break-in there.

Break-in of speakers is bull****. A transducer designer at a known company once
told me that speaker spiders (made of cloth and goop) "do" break-in but that
whole process occurs at the QC station when they come off the line or the first
time you stroke the speaker.

I've conducted 3 experiments with speaker break-in using identical woofers and
24, 48 and 150 hours of break-in (per manufacturers recommendation) and found
that if you measure the T/S parameters of a woofer immediately after break-in
when the voice coil is still hot you'll find that the Fs will have fallen by
4-10% but the Vas (compliance) will have increased by a like amount.

Not only do they sound alike but you'll come to the same recommended enclosure
volume with either set of T/S parameters. Measure the same driver a few hours
later and you'll find that it will have returned to its original T/S
parameters.

So the best that can be said is that speakers may "warm up" but that doesn't
affect sound quality or SPL.

I would have thought "breaking in" was nonsense as well, but I overheard a
conversation this weekend that leaves me considerning the possiblity.

I was at a car stereo distributor's show and one of the guys at the M A booth
was mentioning to the other about how much more likely their woofers are to
blow when hit with maximum power during the first 20 hours or so of play. The
indication was that the moving materials of the speaker are somewhat stiff
after manufacture, and pushing them to their limit might cause the materials to
separate rather than flex.

I thought about this in terms of shoes. They're meant to flex as you walk, but
are usually quite stiff for the first few wears.

If this is true - you may not need to break a speaker in for SQ purposes, but
it might be beneficial if you don't want to blow your speaker apart the first
time you power it up.

Well, evidently Alumapro doesn't break in their drivers, at least according
to Matthew Honnert from Alumapro. However, I've yet to be presented with
any evidence that there's a difference.

According to Richard Pierce, who's examined this very thing, the "stiffness"
of the driver takes on the order of seconds to loosen up, and will actually
return to some degree to its original stiffness after all.

Besides, I would think that temperature would make more of a difference in
therms of stiffness.

well...


i got 1 pair of JL 6" speakers here....and 1 pair of Alpine Type S
5-1/4....


they gonna get 5 min of medium volume....then max volume.... Ill let
you know how it turns out tommarrow

Just put a ball in it and shove it under your mattress.

If such a condition actually existed, which I doubt, the most likely cause
would be adhesive that wasn't fully cured.

By temperature, I meant ambient temperature. My point was that 100 degree
differences in temperature would provide greater differences in suspension
stiffness than how new a speaker is. And even that is almost certainly
inaudible.

Don't forget to put some oil on it and bake it first.
