Have this 8 year old Paradigm sub that appears to ahve a rattle in it when I turn it's volume up. I really don't play it hard at all and the rattle does usrprise me. Anyone hazzard a guess as to where rattles are most likely to be? Should I try to take it apart (how?), or just let it be?

Check and make sure the foam is not deteriorating or coming loose from the cone or frame. The dust cap may be coming loose from the cone. Make sure all of the screws holding the driver in are tight.

Can these checks be made without opening the speaker? If need to open speaker, just undo the screws, eh? Also, let's say I do find deterioration around the cones, can this be fixed?

Yes. This is a visual inspection of the outside of the driver. If there is a grill, you must remove it but that is all you need to do. If this doesn't find a problem, then you will have to remove the driver. A working knowledge of a screwdriver is required.

 

Again, yes. If the surround is rotting away, it can be repaired. Parts Express and dozens of other places offer refoam services from $20 to $100. I've refoamed 4 subs recently and working on two others now. Cost for the four 15's was $20 ($5 each) and the 12's will be $3 each. Ebay has a few foam sellers with great prices and it is extremely easy to do.

Thanks, Robert. I'll try to get to it today to see what the problem is. And if i see anything that's deteriorated or needs repair, I'll let you know for further advice.

Think I fixed it. First tried to remove the front panel...wouldn't budge. Next undid the back and noted that the speaker, it self, seemed to be OK, but wires were dangling. Taped up the wires and securely rescrewed in the back cover. Rattle seems to be gone...for now.

Those wires could have been vibrating against themselves or against the speaker, or against the sound tube??? But in any event, I just taped the wires together and to the speaker so that they didn't have a chance to vibrate. Seems to have worked.
