    Refoam or Replace?

    I recently picked up a pair of Pioneer Hpm 300's for $40, and am thinking of
    restoring them. The cosmetic issues are'nt a problem, but the 8" drivers(woofers)
    are done. They are MidWoofers, and was wondering if upgrading to new drivers
    is the way to go, or refoam the originals. I've heard these were the upgrade to
    the Hpm40 speaker, which was well regarded, we'll see if it is. I'm not to concerned
    about keeping these original, just some good sounds. Thanks in advance.

    Remember, a speaker system consists of three matched components, the cabinet, the speakers (mostly the woofer) and the crossover. If you throw off the balance of any one of those you compromise the sound.

    You stand a better chance of keeping within the original design parameters of the system by refoaming them

    Refoam them. They will probably sound better that way.

    Refoaming speakers is arguably one of the easiest things you can do. That said, I've never done it myself (I just got back from a guy's, who said this).

    Refoaming is a pain. That said, it's worth it.

    Also, check to make sure that the spider is okay, and the voice coil is not rubbing.

    Refoam! You can't go wrong for the $30 to $40 it will cost. I used the professional kit from Winston Organ:

    The people on the phone we really helpful sizing the kit, and it wasn't that hard. It was a bit scary cutting the dust caps off of the cones though! Look at it this way, if you screw it up, you can go with your second option and replace the woofers. Or by a set of speakers you don't care about and do a practice refoam. It is not hard! You just need to take your time. Watch out though, the glue is sticky and can get messy if you are not careful. Feel free to PM me with questions. I am sure you will enjoy listening to speakers that you fixed yourself.
