Powerful, standalone sound that flexes to meet your coverage needs — the Bose F1 Model 812 is a 1000-watt, full-range loudspeaker featuring Bose Flexible Array technology. At the heart of the F1 is a 12-inch woofer nested behind an array of eight high-output drivers. These nine speakers are supported by a lower crossover point than conventional loudspeakers — to give full voice to your sound and deliver clearer, more natural vocals and midrange clarity, even at high volumes. And you control the vertical coverage pattern. So, wherever you’re playing, you can adapt the PA to match the room. With the Bose F1 Model 812, your sound stands alone.nsport.
