SoundTube Weather Resistant Surface-Mount Speakers – SoundTube’s SM52-EZ, SM52-EZ-WX, SM82-EZ-II and SM82-EZ-II-W speakers incorporate polypropylene woofers; 5.25-inch in the SM52-EZ and SM-52-EZ-WZ models, and 8-inch woofers in the SM82-EZ-II and SM82-EZ-II-WX. All four include soft-dome tweeters, and SoundTube’s BroadBeam Ring technology. The speakers carry IP65 ratings, which means the speakers are dust tight and capable of withstanding water jets pointing directly at them. More specifically, the WX models are IP65 rated out of the box, and the standard models meet IP65 criteria when the port plugs are installed. The speakers offer 70/100-volt and 8-ohm bypass. soundtube.com
