    "The floating cone driver"

    I noted that speakers using conventional drivers always altered over time, depending upon what source material and volumes were used - of course, not so easy to distinguish the precise cause in a system context. A simple expression to describe this is "that one can hear deeper into the mix" -...

    "The floating cone driver"

    "The floating cone driver"

    Remember a suspension also means the spider, and if you examine the latter they do not have a homogeneous structure, sometimes having a woven characteristic. Any non-uniformity could easily mean non-linearity effects, etc.

    "The floating cone driver"

    Unfortunately, I can't point to specific papers - it's generally thrown in to refer to the fact that suspensions do not behave in a linear manner, for a variety of reasons. Just Googling, found these two efforts: https://www.klippel.de/fileadmin/klippel/Files/Know_How/Literature/Papers/Aging of...

    Some information/comparisons/clarification wrt vinyl and Redbook CD

    Have done experiments encoding just using 8 bits, with optimal dithering - and this works. Just a pleasant hissing sound in the background, and subjectively I don't feel anything is lost in the presentation. The "dynamics" of the music, as something with gusto and drive, is still all there - and...

    "The floating cone driver"

    Yes. Normal dynamic drivers are "sticky" - stiction is the term I believe is used for this, has been discussed on a number of occasions. I learned that very heavy conditioning, by driving the suspension vigorously with the right music, overcomes this to a large degree - how this manifests is...

    Some information/comparisons/clarification wrt vinyl and Redbook CD

    Quite easy to emulate by creating tracks which use a paucity of bits to encode. There are test CDs, I have a Denon one, which has the same musical passage at 0, -20, -40, -60 dB down, with no dithering. The noise is an "electronic" chattering effect, very distinctive - and is almost impossible...

    "The floating cone driver"

    The fact that the suspension is no longer the crude mechanical mechanism that drivers have had since they were invented is an extremely encouraging sign - a clear marker that they have done their homework is that these speakers will have excellent rendition of low level detail, from a cold...

    Some information/comparisons/clarification wrt vinyl and Redbook CD

    Subjectively, many CD replay systems, and recordings, come across as lacking dynamic range - this is actually an ear/brain interpretation of the distortion artifacts that our hearing systems have to deal with, listening to a type of subtle degradation. The most 'banal' recordings can come to...

    Consideration about Timbre

    And behaviour is identical for a playback system, when it reaches a standard that I call, "competent". A cello, or cornet on a recording also sounds right - if they don't, then weaknesses in the rig need to be addressed.

    Consideration about Timbre

    Yes. "Real content", the musical event captured on the recording, can become completely dominant, subjectively; overriding all other "distortion layers" present, especially that of the playback system. The most remarkable byproduct of that is that the speakers disappear - it becomes impossible...

    How to become a serious audiophile

    CD sounded good to me too, when it initially appeared. I was excited as much as anyone else, because I hadn't realised what was possible in sound reproduction - I was then fortunate enough to make some right decisions in terms of what I purchased, which provided an excellent base for tweaking -...

    How to become a serious audiophile

    Well, I'm still curious to hear what you believe that reason to be ... IME, both media operating correctly deliver the full monty; when working below par the nature of their failings are typically very different - then one can have favourites, depending upon what irritates more ...

    Which audio companies have solid engineering chops?

    No ... important aspects of construction have been addressed in the making of these - if I was forced to use a pricey "audiophile" cable I would probably pick these. Custom manufacture will always cost, irrespective of anything else.

    PHILIPS RED BOOK

    The complication is that the ear/brain adjusts the dynamic range, depending upon the "quality" of what it's hearing - unfortunately, :p, the experience of such is always subjective ... always. Obnoxious qualities in the sound, whether reproduction or something live, make it seem louder, but it...

    How to become a serious audiophile

    Subjectively, vinyl has all the dynamics one could need - real world digital playback quite often does this poorly, which is one of the valid criticisms of the medium. The 'deadness' of much CD replay has caused it to take far too long to be fully accepted by the fussier - a classic instance...

    How to become a serious audiophile

    Of course, digital is theoretically far superior, but typical implementations of the playback chain were sloppy - "the accuracy of digital will fix everything!!" - ummm, no ... Which is why CD had terrible early decades, I was amazed at how awful systems usually sounded - "Can't the people...

    Amplifier And Loudspeaker Interaction

    Agree on active speakers - most power amplifiers are not engineered well enough to do the job of driving typical multi-way speakers competently, no matter what the specs say. A key exception I came across was a Bryston, which performed admirably - a reference in performance capability, for me.

    Consideration about Timbre

    The highlighted is the tricky bit - 99% of what's out there isn't "decent enough", in the reality of it actually working - no matter how much you paid for it, how much other people have raved about how good it is, how brilliant all the technical measurements made of it are ... if it doesn't...

    Consideration about Timbre

    Exactly. Typically, the treble is "offensive", because the the level of audible distortion is far too high in this critical area, to be subjectively acceptable - not from the recording, but from playback misbehaviour. Which is not the fault of the speaker, or the treble driver, but the...
