Hi folks, first time here!

In the next two weeks I will be working to set up a sound installation. I’m wondering about the best way to fixate eight large surface transducer to a concrete wall, a wood door and an air conditioning duct. It’s important to tell you that the exposition will last a 2 months, in a hot brazilian seaside town. https://www.sparkfun.com/products/10975

Silicon sealer.

Gorilla glue.

Epoxy.

I would use silicone caulking compound, guaranteed for outdoor use. It is flexible and sticks to just about anything.
