Title: Waterproofing Speakers
Post by: Sylvestre on November 20, 2013, 01:39:02 PM
Hello,

I am building a robot that needs to operate in various harsh conditions (snow, rain, cold, etc.)  I have designed the robot so the speakers are mounted on the exterior of the robot so they will be subject to thee conditions.  I am considering placing a screen over the speaker and then spraying the screen and the speaker with  super hydrophobic compound called Neverwet.  Do you think this will work?  Will it reduce the speaker's performance significantly?

Thanks

Why not purchase some already waterproof speakers? There are a lot of them available for outdoor and marine applications.

Here is an example http://www.amazon.com/PLMR41B-4-Inch-Waterproof-Stereo-Speaker/dp/B001ES8X9M (http://www.amazon.com/PLMR41B-4-Inch-Waterproof-Stereo-Speaker/dp/B001ES8X9M)

Grrrr >:(
I should've done that in the first place. That's what I will probably end up doing.  Thanks for the link

you probably meant to call that water resistant, not water proof which means down to a certain depth. anyway i had very good luck just putting the speaker in a sandwich bag. virtually no effect on sound at all and you cant beat the price.
