The dimension of my venue (L x W x H) is 50 x 20 x 10 feet, and that of the stage (L x W) is 10 x 20 feet for Live Band House of Worship (acoustic guitar, electric bass, acoustic drums, keyboard, 4 vocals) and Speech. Regarding the vertical converge of TWO F1 812 without Sub, I am not worried about the performance in live band scenario, but I am still worried about that in Speech scenario. Therefore, I worked out a section diagram of the case for your reference. If I want these F1 812 delivers a consistent sound level (say 80dB) to 1st row until the last row, is it feasible? In this case, do you think how much dB values of X, Y, Z can be delivered from F1 812 normally if the spl for the first front row is controlled at 80dB? How to improve it?
Hi KT. What you are asking is the job of system designers usually. ST is correct, we typically point end users to Bose authorized partners.
However, in this case you describe a rather small room, one that will benefit from wall reflections. You will not have any problem filling the room with sound in a speech scenario. In a quick model (using our Modeler program), with the loudspeakers hanging 8' from the floor and 8 feet from the stage wall, angled down at -5 degrees, and with a seated audience, a listener at the back of the room would be only -6db compared to someone sitting 14 feet in front of the speakers. Lots of things to consider here so it's just a rough approximation. For more information and support, please connect with our HK office.
