If the one side is failing, swap the good and bad speakers. does the
bad speaker become good? and the good speaker turn bad? is the stereo
properly grounded?

Any chance that the speaker mounting area could be distorted, which might be
pulling the speaker frame out of alignment and causing the cone voice coil
to rub on the magnet gap?? Maybe some old accident damage? Just a thought.

Very, very common in the high-end and pro audio worlds.

You get two bonuses. Headroom, which can do wonders for clarity, and
no clipping which prevents your speakers from dealing with DC.

There's not much that speakers hate more than DC, which happens to be
0 Hz. (drive it all the way in or out and hold it there!) except maybe
water. <G>

If they're pressed metal frames and you overtorque the mounting screws
they almost always warp.

Have you ever listened to a *continuous* 22 watts, let alone 50? You
don't want to....

Driving a low-powered amp into clipping, yes. But clipping kills
tweeters first, then mids and eventually it *could* kill the woofers.

Overpowering a speaker usually kills the woofers first *IF* you can
stand the level and the racket of the woofer cones overextending and
having the coils hit the magnets.

High amounts of DC voltage usually "cooks" the coils.

Someone else's idea of putting in a "cheap as possible" speaker is a
start, but since the dead speaker's mate is a known good speaker, use
it instead. If it stays alive, you'll have to chalk this pair of
failures up to Murphy.

FWIW, I was a tech in a hi-end audio shop and we were known to do
intentional speaker-killing at times.. under "controlled conditions" you
know..
