I may not be as serious of an audiophile as many of you, but I would like your advice. I have a decent system in the house. I would like to be able to also enjoy our music on our deck. The simplest way seems to be to find a wireless speaker system. Even if I need to bring it in and out, that is OK. I just want a set of speakers outside that have reasonable quality and volume of sound that we can enjoy for an evening in the porch swing or when we have a gathering of friends. Any recommendations?
