Speaker break in - is it real?

[Sydney]

It has been claimed that 90% can't discern difference beyond mp3. Perhaps the remaining minority are the ones asked for opinion on Audio matters - including how something sounds to them.

Oh boy, bracing for another bunch of "LMAO" posts...

Damn I didn't realize my LMAO effects certain people so much. rolls eyes. LMAO

Maybe I should warn people fist before I post so they can brace themselves for the impact. LMAO

Now if it offends you that much let me know because IDGAF. LMAO

‘What measurements do not tell is the very sound of the speaker unless displaying serious linear distortion. The level of transparency, the ability to resolve micro-details, the "speed" of the bass, etc., cannot be derived from these data. Distortion measurements rarely tell much unless seriously bad, and most modern drivers display low distortion within their specified operating range.Â* Many people put way too much into these graphs and my comments here are only meant as warning against over-interpretation. There are more to good sound than what can be extracted from a few graphs. Every graph needs interpretation in terms of what it means sonically and how it impacts our choice of mating drivers, cabinet and crossover design. What measurements certainly do not tell is the sonic signature of the drivers, because cones made from polyprop, alu, kevlar, paper, glass fiber, carbon fiber, magnesium, ceramics or even diamonds all have their way of colouring the sound.”- Troels Gravesen

The first intelligent post in this thread.Â*

Just wait until he graduates high school. Then he'll not just know everything, he'll have a diploma to prove it.

I lost my diploma, so I never graduated from high school which means I do not know everything.....On the other hand Gurus know everything without ever experience it first hand because there magical diplomas convinces themselves that they are demi-god like. LMAO

No way, ACCORDING to GURUS they know everything without even hearing said gear first hand as its all about the Data. LMAO

Good post by the way.

Claimed by who and how accurate is that study?.....If that is accurate then it just proves that some people can discern the difference which means its totally possible and they are the ones that should be hired for there opinions on audio matter but even at that it would still be there OPINION SMDH.....Of course I doubt that 90% number unless it was done on 8 billion people world wide.

Easy - It was a joke ( sorta like nine out of ten British housewives can't tell the difference, yada, yada etc )

I run a lower than Fs sine wave at a high enough level to just approach xmax. Some use pink noise, but the point is to loosen the suspension and spider. A sine wave lower than Fs does that more effectively than pink noise with minimal power, and with the driver not mounted does so almost silently.

So you take the time to "Loosen the suspension and spider" before measuring yet claim speakers DON'T break in?

The nice thing about this hobby is you get to hear what you hear and I get to hear what I hear. I believe I've heard woofers sound better after playing them for quite some time.

YMMV, Mark

I never said that.

So what are you saying in post # 24 ?

"This measurement can also be performed as an accelerated life test for separating fatigue from break‐in and assessing the long term stability of the suspension. "

from:
https://www.klippel.de/fileadmin/kli...on_Klippel.pdf
"The time varying properties of the suspension are caused by reversible processes such as the viscoelastic behavior of the suspension. The temporary decrease of the stiffness after large peak displacement recovers slowly after removing the stimulus. The stiffness also varies with the ambient temperature, humidity of the air and the absorbed moisture in the suspension material." ( emp. mine ).

Yes, break in occurs as the suspension and spider warm up and get softer, the driver's Fs drops a few Hertz. Mr. Bill notwithstanding.

You have to remember that Mr. Bill is the expert on all things loudspeaker related.

Very pathetic how PE moderators pick and choose who's posts to delete and other's not.

That would be whose. Who's is a contraction for who is.

Figured it meant more coming from Klippel, rather than a non-guru such as myself.
