The Bogen ASM1 Easy Install® Self-Amplified Speaker is a surface-mount speaker, designed to typically install in less than a minute. Installation is a simple, three-step process that does not require tools. First, four specially-designed studs pierce the ceiling tile. Second, two custom-designed wing nuts secure the speaker to the ceiling. Third, standard wire nuts make the 24V DC power and audio connections directly to the color-coded studs. The ASM1 is lightweight, durable, and features a lowprofile contemporary design, making it versatile enough to be installed in just about any installation with standard ceiling tiles.

The ASM1 is a 1-watt, self-amplified speaker. There is an exterior volume control for easy balancing that is easily accessible, but doesn’t attract tampering.
