Outdoor Speakers


Hi, I have a small place a block from the beach with a porch out front where we spend weekends in the Summer. My family spends a fair amount of time eating meals, reading, playing board games on the porch. I would like to install out door speakers so we (me) can listen to music. The porch is covered so they would not be exposed to the rain but the salt air does corrode just about everything very quickly. I think I would likely store them inside the house during the week for that reason. Are there any speakers that anyone can recommend? Thank you.

I run Niles OS 20's - not even sure if they make them anymore but they have a nice bass response for their size and have been indestructible.
Thank you all for your responses. I will research each of them and appreciate the headstart you have given me.
You might like the Soundcast speakers. They are high quality, onmi-directional outdoor speakers that are meant to be portable. You can run them from a Bluetooth source.
