I am concerned about water damage to CA 18's if used in-door. I have an old (like 20years) 6.5" alphasonic sub mounted in one door of my MR2 and after a couple of seasons I can see water stains on the bottom of it. I live in Canada, so I suppose condensation is a real issue in the winter as well as the usual rain in the warm months. Anyone have any experience in this regard?

I am wondering if aluminum coned drivers are a better choice for door use? I'm considering the LA18 or RS180, but would prefer the broader bandwidth of the CA18.

I dunno if aluminum is "better" for in-door installs, but I would have to agree that it is the better option if you have a moisture problem.

The CA's are coated though. I would imagine they should hold up fairly well. And given their price point, replacing them in a few years may not be that big of a deal.

The CA18RNX is coated... but I still don't think it will like direct moisture. I think it would hold up fine in a car... haven't heard/experienced any problems so far.

It may be coated but i don't think it's coated on the back of the cone where it would make a difference in this case or am i wrong?

You are probably right 300. If he is dealing with a lot of moisture the paper cone may be an issue.

For me the price/performance ratio on that mid is unbeatable. It is very inexpensive, and could be easily replaced if you could get maybe 2-3 years out of it.

I've noticed though that pulling 6+ yr. old paper cone stock oem drivers out of old car doors, that they held up pretty well?

I'm wouldn't be especially concerned about it. As NPDang mentioned, what do you think that most OEM car cones are made out of? I'd be more worried about dust or a little bug getting in through the spider ventilation and finding its way into the gap. However, if you're paranoid like me, you could consider cutting a Cool Whip container or something similar in half and using each half as a rain shield for a speaker. (The Publix house brand one sounds just as good ;) taste of the product I don't know because I don't eat that stuff. It went in the trash.)

Then again, if you're paranoid like me you probably put clay and lead shot on any stamped steel baskets in your system, made your drive-unit mounting rings using constrained layers, and so on....

I am in "Greater Metro Atlanta area". :D

Specifically Norcross. But, like you, I just say Atlanta. Nobody knows where the sleepy little village of Norcross is.
