I've been using these for about a month now on our backyard deck via zone 2 on my Denon AVR....mostly Pandora or my iTunes library via Apple TV/Airplay. Yes, it's compressed digital music (converted to analog as the AVR cannot output digital signals through zone 2-something I learned while researching adding outdoor speakers) but they sound great.
I listened to several others in the store and these won out. They simply sounded better than everything else Best Buy had to offer. There are more expensive and potentially better speakers out there but naturally I wanted to hear what I was buying. I was a little reluctant to spend so much when I anticipated only using them a few times from April to October. However, they sound so good, I've made more time to sit outside and enjoy them. Plus, they were on sale that week so I pulled the trigger.
I brought these Def Techs home and compared them to another great pair from Best Buy, the Klipsch KHO-7. While the Kilpsch sounded and looked great and were cheaper, they sounded, well, like outdoor speakers. Hard to explain since sound is so subjective. The Def Techs sounded more like quality indoor speakers in a weatherproof housing. Plus, they looked better installed. If you have the extra cash and are serious about good sound (even if only pumping compressed digital music through them), these are a great buy.
