Bose F1 Model 812 Flexible Array Lautsprecher

FLEX Array: The exclusive flexible construction from Bose can be adjusted in four different forms, so that you can choose the best radiation pattern at any time.
Array with eight drivers in the mid / high range: eight vertically mounted drivers, each of which is attached to its own waveguide, ensure optimal sound reinforcement.
12-inch LF driver: the powerful woofer delivers top sound even in the lower frequency range.
Integrated 2-channel mixer: 2 inputs with independent control, independent XLR, 6.3mm stereo jack and cinch inputs

The eight drivers of the F1 Model 812 Flexible Array Loudspeaker are mounted on an especially developed, flexible construction. The speaker can be easily dragged or pushed in four vertical positions: "Straight", "J", "Inverted J" or "C". The system then automatically adjusts the equalization, thus guaranteeing an optimal tonal balance in every position.
