Along with their great lines of indoor products, Bose has a line of outdoor products as well. From porch speakers to marine speakers, they have a pair for every need! The 251 Speakers are for use in all weather, being intense sun, to ice and snow. Every pair is tested to ensure reliability and performance no matter how extreme conditions are outside. These speakers are designed to be used over wide areas, and are designed with Bose's patented Articulated Array speaker design to produce low frequencies with minimal audio distortion. In the box, you'll receive a pair of speakers, mounting brackets for wall mounting, mounting hardware, rubber feet for the speakers if you decide against the wall mounts, and knobs for adjusting speaker settings. Remember, you will need speaker wire to hook these up to your entertainment system! Overall, this is a great set of speakers for any job outdoors.
