Over time if the coating is not good enough, it can degrade and cause it to "blush," or have a cloudy white haze.
Paper is very porous and I am pretty sure they might have used a sealer coating before they used a urethane top coat over it. I believe the polymer degradation over time is the real cause of losing the clarity of the coating that gives the haze. If it is exposed direct sunlight then there are more chances of UV degradation of this coating and it will not be always uniform.
JVC speaker manufacturers might have improved the urethane coating on newer M90s that still stays clear without haze. This is why we have seen many of them with the blue cones. If you check teh back side of the cones they all are blue in color, So two different speaker coatings went on these speakers and one version was the better coating.
This is my thoery

. Was thinking the same. There is no logic at all to make yellow overload area. Use to work with lot of sound equipment and never saw yellow for the overload area 
. Here are some examples of faded watches as well. I dont care about m90 and yellow VU's anyway. But physical laws are present , like em or not
. And there is no "yellow" versions of those watches for sure

Does this statement above not disprove the validity of basing your opinion on the brochure image
mmcodomino said:I have never seen a pic of an M90 in a sales brochure with yellow meters.
Regardless a red meter would have to fade through a few shades of orange first before turning yellow.
Here is a JVC example of a meter with yellow

^ This isn't a good comparison because that needle is coated with "glow-in-the-dark" material so it would fade way different then the VU meter print ink. Plus that needle faded back to it's original color from orange. Glow coatings start out that lime color then get dyed to the colors they want to use.

Well, whatever
Physical laws cannot be changed .
Red is the color that fades the fastest in sunlight.
We have also all seen faded speakers which were originally black turn light grey (see multiple GF777s for example).
Now why should it be different with the M90? Cause JVC uses everlasting ink?
I could be wrong though and JVC released a pre-faded version as a special edition called "Future M90"
Anyway, anybody who owns an M90 - faded out, not faded or with yellow, purple or blue VU meters - can consider themselves lucky.
I may throw in that the GF9000 - as Bobby stated in another thread - is the most famous example of fading red in the VU meters.
So damn, stop all the debating and crank up your M90s

My yellow metered M90 sold for $2650.Fatdog said:I'm surprised no one from here has put up a super rare M90 with yellow meters and gray / black woofers on eBay yet. You know something that rare and special would go for thousands of dollars.

This thread is laughable.
Let's just close the subject and we all believe what we want to believe
