The Extron SM Series Surface Mount Speakers feature an innovative, patented wall mounting system. Speed up your speaker installations with a concealed speaker mounting solution that can be installed during rough-in with speaker cable terminated to the integrated wiring contacts. During final equipment installation, simply slide the speaker onto the mount to secure it in place, as the speaker is automatically connected to the wiring contacts in one installation step. A hidden locking mechanism allows the speaker to be secured into place with a unique key to deter theft.
