I'm looking to buy and mount some outdoor speakers near my pool. I'll probably mount them on my house which is only 6 feet from the pool. I'm have no experience with outdoor speakers. Any suggestions would be appreciated. Wireless a reliable option?
I like Klipsch speakers, but they are rather expensive.

I have a Marantz SR5007 on the way for my home theater system. Would the 2nd zone be useful for the pool side system? Sounds like I have to run an ethernet cable to the SR5007 to access the network. Marantz evidently doesn't offer a wireless option. I really don't want to run the ethernet cable, but I will if it is the best option.

Or should I just purchase another not so costly receiver which I can place with my router and hard wire directly to the receiver and run the pool side speakers from this unit? And if so, any recommendations on the unit? Should I go with a standard 2 channel receiver?

Lastly, my wife and I both have iPhone's. What advantage if any does Airplay offer?

Thank you in advance for any information.
