Not only does the cone stiffen and rip in age but there are other 
factors to contribute to the failing speakers. After a while the oil 
used inside the "magnetic core" (where the cone is wrapped with 
magnetic wire and is slipped into the base magnet) dries out and 
causes friction. The number one casue of "vibration" sounds coming 
from the speaker when the volume is increased is that there is a 
foam ring that attaches the paper cone to the metal casing of the 
speaker that acts as a spring/resonator/etc. The glue that is used 
to attach it to the cone/metal dries out and starts to peel up. You 
can actually fix that by removing the speaker and finding out where 
it is begining to peel and just simply re-glue it...cheap fix. The 
ring usually peels off when either A. a new more powerful stereo 
system is installed or B. The volume is raised past it's "usual" 
setting. I've personally repaired a few speakers and actually have 
rewound the base of the cone with new magnetic wire...but it's not 
always worth it. If buying a new set of speakers try to stay away 
from paper cones since any moisture/water will cause them to warp.

Just a little info.
