S-85 and the foam bits - diffraction limter?

    All,

    In the picture included shows my centre speaker from M&K; the S-85C. Notice the foam bits around the tweeter.

    I gather that these 'foam' parts on my centre, right and left speakers are some kind of diffraction limiting device that stop sound from hitting the edge of the speaker and creating a new source sound. I notice that the S-85 also has a rounded edge that also helps to reduce diffraction but are these foam parts for the same reason?

    Regards,
    Brad

    I don't know what they are for, but IMO they really spoil the look of the speaker:(
    Why aren't they black?

    Can't see them when the grills on. Perhaps that's what there for - to reduce the diffraction around the tweeter caused by the grill's frame.
