If I use my pa/disco speakers outside.The paper cone would become brittle eventally.
So would polyproplene.
I've heard Selenium have special Quartz composite cones,to handle UV light,some heat,and they are water resistant.
Also Peavey use Kelvar for their Black Widow series speakers.
Would the following be able to be able to cope with direct sunlight without degrading;
Carbon fibre,Fibreglass,Aerogel,TPX,Kelvar,Quartz Composite,Aluminium,Titanium.
I know polyproplene,paper,and doped paper, go brittle in sunlight.
Or the alterative is to use horns, such as J-bins and W bins,and where speakers are mounted inside the cabinet such as band pass.
These are all sub bass or bass enclosures.For midrange you properly need a expotential wooden flare path,to protect the midrange from direct sunlight.And tweeters are mostly inclosed horns anyway.Except for dome,cone,and some small bullet tweeters.
Also which of the above speakers are water resistant,so if I use them outside,and it rains,the cones dont go soggy and fall apart.
Polyproplene is water resistant,but then it's but UV or sunlight resistant.
Is there a pa/reinforcement speaker driver which can be water resistant,uv resistant,sunlight resistant and have high power handling and still sound good[Especially in the bass range]
The only one I can think of is the Selenium Quartz Composite cone speaker drivers,but I wasn't sure if these had high power handling as well.

Kevlar speaker are generally wheater resistant. They would handle uv pretty well but 99.9% of speaker will not handle water. Kevlar will handle moderate condesation.
What about using Marine/car audio drivers?
I dont think the cone materials will be a big problem as the surrounds is what will decay first. IMO

Even if the cone / surround is made of something weather-resistant - check the material of the spider also.
Would oxidation also cause a problem for VC wiring?

Another problem is corrosion of the zinc plating of the magnet polepieces.
This galvanising can oxidise and swell, and cause scraping of the voicecoil in the voicecoil gap.
Moisture is a real bad idea for speakers.
