I'm looking for a pair of inexpensive outdoor speakers to replace ones that were mounted on the back of my house by my deck. I've looked at several brands of outdoor speakers and whether they say weather "resistent" or weather "proof" they all say that they shouldn't get rained on. I'm not sure what the last pair I had were, but they lasted eight years. Are any brands (technically) going to be able to survive the rain? Any suggestions?
