I finally found time to install these speakers for our back deck. Instructions were clear and installation is comparatively easy, thanks to Bose’s bracket system. It took a little over one hour to remove the old speakers and install the newThe sound quality is excellent. These speakers replaced Realistic speakers from Radio Shack (remember them?) that were installed in 1984. The sound quality is almost identical. I was surprised and would look into other speakers as a cheaper alternative. My speakers are installed under a part of the deck that is covered, which provides protection. The Bose speakers seem more durable than the old ones. I expect these speakers to last decades.FYI, these speakers are wired to amplifier. I had a wiring system in place and was looking for wired speakers. Also, they must be installed at least seven feet apart.Overall, these speakers are expensive, high quality, and an excellent choice for outdoor music.
