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

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

    "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.

    I never said that.

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.

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

    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.

    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.

    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

    The data backs up the break in period for the driver at first but after that, I think it is just the person getting use to the sound of the speaker.  When I have demo speakers before, it takes a couple hours or coming back a day later to allow my ears to adjust before I can give an honest opinion about a speaker.  Again after mechanical break in and motor warming up, I think it is all in your head.
