Hi, folks. Big BOSE live sound fan here. We're considering purchasing at least four (4) F1 stacks (812s and subs) for use in smaller venues as portable mains. Concern / Question is how best to set, hang, mount, splay, cluster, etc.. at least 2 tops per side (when needed for additional coverage / spl) without encountering nasty comb filtering and HF cancellation issues? Please advise and thank you.
Thank you for joining the Bose Pro Portable PA Community and Welcome!
This is a great question. The simplest formula for the F1 Model 812s is: put the loudspeakers where you need the sound.
We've talked about this question at length at Bose. There's not much if anything to be gained by clustering the F1 Model 812s. If you want to get wider dispersion, then spread out the units and place them close to the area you are trying to cover. Although some overlap is inevitable, try to avoid it.
For the F1 Subwoofers, you can put them all together, or separate them in pairs or individually with the F1 Model 812s depending on the size and shape of the room.
Does that help?
Yes. Thanks very much!
Would there be any pros and cons if an 812 was place next to another 812? The only difference being, the second 812 will be placed higher than the first so the horizontal coverage does not overlap?
You're going to have unavoidable interaction between the twelve-inch drivers in the frequencies below 600 Hz.
It's better to put the F1 Model 812s where you need the sound instead of putting them in pairs.
Ah yes. The 12in driver. I swear sometimes I forget about him hiding in the back. Good point.
