Speaker composition: is a grey-polymer coated woofer not as good as aluminum?

    Just curious. I have some speakers where the cone is aluminum and another pair as grey-polymer coated. Which is better?

    Also, I see the tweeter is listed as ferro fluid cooled aluminum and the other speaker's tweeter is listed as just dome tweeter.

    These are Yamaha speakers I have.

    The cone material is only one small aspect of the sound quality of a speaker. There really is no one "best" material. They all have strengths and weaknesses. There IS a lot of marketing hype surrounding cone materials. Interestingly enough, many of the best high end speakers use variations of paper cones and silk or cloth dome tweeters instead of the latest material. It's the overall design that counts.

    Dave,
    Ferro fluid is used in tweeters to increase power handling by heat dispersion. Read this thread to find out more info on driver technology.
    Cheers,

    Dave,

    For Midranges and Subwoofers a propely implemented paper
    cone can outperform an improperly implemented alloy cone.

    Every material has stengths and every materials also has
    it's weakness's. Many companies will use plastic cones that
    are "Aluminum Plated" for looks, that's all it amounts to
    because that millions of an inch thick layer of aluminum
    plating they put on via electrochemical process hardly
    stiffens the cone like they "claim".

    With a lot of cheap brands they do these things to make
    the speakers look high end and to have flash, so that they
    may appeal to people shopping for a speaker based solely
    on asthetics alone.

    That being said, My mid ranges are a blend of magnesium and
    aluminum alloy and are hemisphericaly machined (no seperate
    dust cap) and I love the way they sound. They were never
    used for looks (black anodized, they hardly stand out from
    the rest of the black speaker) they were used because they
    are very high resolution, very sensitive and they do a
    superb job at midrange. Whoever uses a Metallic Mid or
    Tweeter just has to make sure they know what frequency said
    driver "rings" at, and cross it over well below that threshold.
