Pros Incredible sound detail in an outdoor environment
Cons Fairly pricey but worth every penny
Summary I actually bought the Niles OS 7.5 speakers but the 6.5 is a similar quality. I have installed them outside on my patio against the house and just under an overhang. The sound detail is awesome, even outside. The sound also carries very nicely so you can be out in the yard without cranking up the volume and blasting the people on the patio.
No problems with them getting completely wet in the rain and still sounding great.
