Speaker Placement

After my recent outing, I'm not worried about they system covering the dance floor. Question though: any recommendations on how far apart to place my two systems.

Hi DJ8X,

As long as the F1 Subwoofers subwoofers are separated, there's going to be some interaction between them. There's no official recommendation about distance between systems.  Let's hope others join the conversation to share experiences.

Oh ok. I was just thinking about how to take full advantage of the 100° dispersion as it relates to room size. 

I've heard/read of guys placing them at far as 30ft apart.  

Hi JD,

Do you have any thoughts on ideal placement (distance between two F1 Stacks)?

Thanks,

ST

One of the reasons I bought into the Bose F1 system was because I wanted to eliminate speaker stands. My options were Bose L models (which I don't like because I'm a bass junkie), or the RCF Evox models. I went with the F1 because I was able to eliminate speaker stands AND rival my QSC rig (2 k12s and 1 KW181).

I have concerns now that the integrated stand will not get the speakers up high enough as I am accustomed to. I don't want to put my 812s on stands because that is taking a step backward in my opinion. Also, subs hit well when they are coupled or placed by a wall. I don't want to put my 812s on stands just to couple subs.

I want to have 2 F1 Systems sitting beautifully on each side of my station. However, separating the subs like this will give me uneven bass coverage and cancellations...maybe not directly on the dancefloor where it counts, but throughout the rest of the room. This may or may not be a big deal.

So to cut down on cancellations and gain some db, I will be purchasing a 3rd sub. This sub can be place under my table and technically between my other 2 subs that have the 812s on top. 

Anyone have any other suggestions. I'll try anything to keep me away from speaker stands.

I have gotten have gotten great results (indoors) in rooms rated for 350-400 people spreading the stacks out 25' apart on either side of the stage (when doing sound for bands). 

As far as DJ work I put usually put the F1 stacks ten feet apart and have also gotten good results (indoors). 

Outdoors I always run subs together and put 812 tops on stands. When ever I don't do this I do hear lots cancellation issues in the low frequencies.  

The height seems low on the stacks (if you are use to traditional PA speakers on stands), but with the design of the F1 812 tops it is typically not needed to get them any higher than the stacks provide. 

I have four F1 subs and have never felt the need to use more than two at my DJ shows having plenty of bass so far...

If you need more bass than two F1 subs can provide... I would buy two more subs and run them one on each side of the stacks... I think if you just add one in the center you may just add more issues with cancellation defeating the purpose. Although you could always try a third sub in the center and see if you like how it sounds to you... 

I play a small steady gig and will be able to mount a speaker stand on the wall next to my guitar hanger ...

Moved to a new topic in the S1 Pro System forum. Please follow the link below.

@jdbassentertainment.com thanks for the insight. I will follow your outside suggestions as well as the indoor. Here's a list of diagrams that show bass nulls associated with different sub placement. This is why I was considering a third sub vs 4. 

This is 2 coupled together

This is 2 separated

This is 3rd sub in line 

This is 3rd sub 12ft behind line

This was how i could keep the beautiful aesthetics of the F1 System and minimize low end cancellations. 

Interesting, if you get a third F1 sub please let us know how it goes!
