Rattlin' PSW-300 subwoofer...

i have a PSW-300 subwoofer... and to be perfectly honest, the sub has been making a rattling sound since day one... even at moderate volumes. When I bought it, the dust cap fell off the driver before I had a chance to try it, I returned it to the dealer who then fixed it... don't know if he replaced the driver or just glued the dustcap back on.

Anyway, did the PSW-300 have a problem with a rattling sound? It really sounds like the rattle is from the cabinet and not the driver but am unable to determine the exact location since the sub is a bandpass design and located in a separate chamber in the box.

    Hello,
    Actually the PSW300 is one of the more trouble-free sub-woofers we've made. It would be a good idea to remove the unit's AC power cord and take out the screws that go around the circumference of the amplifier's input plate. Once these are removed the entire amplifier assembly comes away from the cabinet. You can then disconnect the two wires going to the internal 10" woofer. Then you can take out the screws for the woofer and then remove it from the same opening as the amplifier. Then you can examine the area of the woofer near where the cone attaches to a corrugated disc, called the spyder, and see if this has come away from the metal basket. Or, if this area looks fine try gently pushing on the cone's surface, trying to push equally on all parts of the cone. Listen to hear if there is any rubbing or scraping sound as you move the woofer in and out.
    Regards, Ken

    The spyder has separated from the speaker basket... can this be self repaired or is the driver toast?

    Hello,
    This can be repaired if you are careful. You would want to use one of the CA type glues, such as "Crazy Glue" or "Super Glue" in the gel form. I believe the gel version of these glues are a little easier to control. It can also be helpful to use a wooden toothpick to, carefully, lift up sections of the spyder and spread the glue where it needs to be.
    But if you are patient and bond small sections of the spyder to the frame at-a-time you should be able to keep the spyder centered on the frame.
    Regards, Ken

    OK, thanks... I bought the Crazy Glue and reattached the spyder to the frame... Sub sounds better than it ever has... it was rattling since day one and i never bothered using it or checking it out since I had other subs in the house...

    Hello,
    Good I'm glad the repair went well, that is a nice sounding sub. Very low in bass distortion as a result of the band pass design. One of my favorites.
    Take care, Ken
