    OK, the dust cover over the voice coil on my speaker was rattling a little. It had become loose on the bottom so I completely removed it.

    Does this serve any purpose other then preventing dust from entering the voice coil? Should i glue the dust cover back on or get a new dust cover?

    The speaker still sounds fine without and I normally leave the grills on (Paradigm suggests you leave the grills on). These speakers are about 8 years old. so No warranty.

    Thanks for any help.

    it's for protection. if it's paradigm, i'd give them a call and ask for their recommendation on what to use to reattach it.

    dust damages coils its a very good idea to re-attatch the cover ....its would be bad to have the dust eat away at the protective coating around the coil or maybe even seize the coil ...

    The dust cap seals the speaker, if you have leaks the tuning of the ported enclosure will change.( like having an extra hole in a flute ) Also the dust cap depending on design can effect the higher frequency range of the driver.

    The dust cap on these speakers is an open weave mesh... ie. air could always move freely through it so I am not too concerned with the porting change. I leave the grills on these speakers always.. so dust can still be a concern but less of one. What I was wondering is will it effect the higher freq. of the driver.

    I would reattatch the cover simply because it is meant to
    be there.. Speaker Grills or not, dust can still enter the
    voice coil and will act like sand.. It can deteriorate the
    shelacking on the voice coil or just jam it up in time and
    either way that is a bad thing..

    Take come elmers glue and put it in a tea cup and dilute it
    with a little water untill you get a semi thinned mixture
    that will be easier to apply. Soak a q-tip in the solution
    and use that to apply the glue to the dust cover and to the
    speaker cone and then simply reattatch.
