Hi, I am trying to decide on a pair of polk speakers for my backyard. I am using a Sonos ZP120 as the amp cause I have a 3 zone Sonos system in my house. I found that I can get the Atrium 60 for 200 dollars the pair or get the new Atrium 6 for 400 the pair. Can anybody tell me the difference on these speakers. I mean is there any audio quality difference? Are there any new features that would encourage me to put in an extra 200 dollars for them? Thanks.
