Completely false. marine stereos have completely potted circuitboards and other
anticorrosion measures that no car stereo has. You just don't know what you are
Same goes for boat speakers. You can point the garden hose right at them with no
ill effects. You sure can't do that with car speakers!
You shure can get a plastic coned car speaker wet no problems at all ,
nothing to corrode, where you been livin in a time warp , Talk to
dealers of stereos they say the guts are the same for 95 % of them
and marine grade doesnt mean they take water well . The lifespan on
your everyday marine CD player is less than a cars unit

Wrong again markie boy. It takes more than a plastic cone to make a spaeaker
marine grade. Car speakers have voice coils that are in no way protected from
the effects of damp salt air. The cone material is only one factor. The frames
are also not suitable in most cases.
Stereo sales people are not likely to know about the differences in marine
equipment. They want to sell you what they have on the shelf so they can collect
their commision. The marine versions DO have essentially the same guts on a part
for part basis, except many of the metal parts are made of different materials,
and the boards are potted.
The reason a marine CD player doesn't last as long as a car unit is because it
is in a very harsh environment. a Car CD player in that environment would last
even less time.
Wrong again Binary bill All voice coils are sealed. otherwise there
would be a Direct Short, commonly refered to as a blown speaker. Did you
ever look at one or work on one . Didnt think so. Did you ever look at a
blown coil from overvoltage , well the coatings can be burnt brown. And
what are they treated with? Years ago shellac or varnish. Today,
weather restistant polys, of different types.
So you figure it out , A UV resistant , water proof rubber
surround, cone, treated windings and magnets, sprayed steel , or
aluminum frames- baskets, plated terminals and waterproof insulating
blocks. Forget your sales brochure, forget what they hype, put your
logic to work . Whats the difference

Clearly you have no idea how a voice coil, or a speaker for that matter, is
constructed. Voice coils are normally not sealed. There is an opening that is
exposed to the air, that can allow water to fill the gap.
I have re-coned more JBL and Altec speakers than you have ever held in your
hands. I was a factory authorized servicer for over 40 brands.
During my many years in the consumer electronics business (still hold a valid
CET license with an unlimited rating) I was involved in every facet of
electronics including retail, manufacture, design and service.
The wire is sealed that is what I meant by sealed thats all that
matters, Ive been taking them apart for 32 yrs so I know how they
work Im a musician and have fried plenty for you to rebuild
I still say top line car speakers are sold as marine. Same line, same
top standards . Uv exposure on car rear window deck speakers is
continual. And heat , well , easily 140 continous. So then again what
is the difference, and who makes potted boards on regularly priced
marine CD stereos

Already explained that several times. Humid salt air is nothing like what you
will find in the rear deak of a car. The laquer coating on voice coil wires is
not gonna help at all when salt and humidity get in the gap. You show me a car
speaker that works when completely submerged in a bucket of salt water, and I'll
agree with you that you have found an example of ONE car stereo speaker that is
the same as marine grade.
All of the major brands that offer a marine grade radio. Every single one.
