The F1 Model 812 from Bose is a powered flexible array loudspeaker that offers four different vertical coverage patterns, allowing users to optimize their sound to fit the performance environment. So whether you're playing at floor level, on stage facing a dance floor, or facing raked seats or bleachers, you can adapt your PA to the room.

The speaker features eight mid/high frequency drivers that are mounted on a flexible baffle, which allows you to push or pull the array into position to create four vertical coverage patterns: "Straight," "J," "Reverse J," or "C." Once set, the system automatically changes EQ settings to maintain optimum tonal balance for each particular coverage pattern.

The F1 Model 812 also features a high performance 12-inch woofer that provides strong low-frequency output, and an integrated 2-channel mixer. Each of the mixer's inputs feature independent level controls, and can accommodate XLR, 1/4-inch and RCA connections.
