The Bottom Line: I put a lot of research listening to the sound of other speakers before purchasing these and would definitely recommend them. They have superior sound, making them worth the money.

The speakers have an excellent sound quality that you do not expect once you get them outside. Most of these type of speakers sound wonderful in a controlled indoor environment where you purchase them but when you get them outside the sound is nowhere close. These however, almost seemed to sound better outside.
I could not believe the range of sound and how well the music spread throughout my patio. I had purchased the Bose 151 for my last home and the sound quality was very good but nowhere close to these. Since the 151s do not come with a quality bracket you have to purchase them separately for almost a hundred dollars. That makes the Bose 251 with the much superior sound quality a better buy.
Since I have only had them for a month I did not give them an excellent on durability the outside does seem a touch flimsy. I did not give them an excellent in imaging because they are in the wide open outside and you can never match the sound quality of an inside environment.
The brackets are very easy to mount and it is easy to adjust the angle up and down once they are mounted.
