Running multiple F1 systems side by side

Does anyone have any experience with running multiple F1 systems side by side?

We own 8 of these systems, and had an outdoor event that was supposed to only be around 1,100 people.. When we realized that it would be closer to 4k people, we panicked and used EVERYTHING WE HAD lol. 

The concert went smooth and sounded great, but I knew that we'd be introducing a nice amount of cone filtering due to the last minuet judgement call. There was some slight phasing issues, but not so much that we had to unplug the PA.. We actually made it through the whole gig without issues.

My question is... How many F1 systems can you daisy chain before having this type of issue? The F1's and subs have little groves on the side that let you know that they are designed to run in tandem, but I cant find any info on how many you can run before having issues. 

How far apart should the speakers be to reduce filtering? 

I believe by "cone filtering" you are referring to comb filtering, correct?

You'll experience this with any loudspeaker at distance in a stereo configuration, but close together like this you will experience more of it. The F1 system was not designed to "cluster" like this and for other larger events you may want to consider renting or setting capital aside for a larger system to handle larger audiences.

Yes.. "Comb" filtering lol.. Sorry, I typed this out over my phone, and autocorrect clearly knew better than I lol. 

Thanks for the info.. That was my main question, if the systems were able to be used in a clustered setup. I totally agree that a larger rig is needed, however the company is owned by my Dad, and he SWEARS by these things. The sound great, and I was shocked when I first heard them, but he went on a tangent and bought a garage full of them lol. 

I've seen photos of other guys using 2 sets of them with the speakers being spaced around 10ft apart on each side. I wonder if that makes things any better for them. My thoughts for the future should another event present itself on this level is to set a pair on the stage, then setup a delay system about 75ft back. That will fix coverage issues, and keep us moving. 

Thanks for the feedback. 

You need to stagger the grills height wise so that where one ends another beings (per side)... I suspect in practice this might be very hard to do using four F1 tops per side...

I have been trying to find the best way to run multiple systems as well.  How did you daisy chain so many?  Example left 812 to the other left 812s and left sub to other left subs? @jdbassentertainment.com Can you show an example of the stagger grills?

yes.. thats how I did it. I ran Left, Right, and Sub on Aux. all subs were daisy chained together. left speakers jump one to the next, same as right. again.. runing this close will cause comb filtering, and slight phasing.. .I'm going to see if I can rig a system to stack 2 of the tops on top of one another. That may be a better idea to get it done. 

Please excuse the 2ND grade drawing, but you get the idea.EFB92475-01B9-4265-920D-8147745D3548

Considering the premium that Bose charges for this product, I would look for a proper line array or tops that can be arrayed to increase coverage and output.
