Are there any good plans for an outdoor 2 way speaker? Mainly the drivers are what I"m curious about. I can put enough paint or even plastic dip on the box to keep it water resistant the drivers are my main question. They would be housed under a porch roof so they should never get directly rained on. I'm thinking 1" tweeter and 5 1/5 or 6" woofer to get decent base out of. They would be powered of my Onkyo 606 so about 90 watts max per speaker. Any suggestions would be greatly appreciated.
