I'm planning on upgrade the sound quality around my pool this season. Currently I've been using my Bose docking station with an iPod. It did a good job but this year I've decided to get some outdoor speakers and a receiver. For the outdoor speakers I've been looking at the Bose 251. Does anyone have these and what are their thoughts on them? What is everyone else using for their outdoor speakers/systems and are they happy with it? Any suggestions would be greatly appreciated.
