Speaker Width?


Hello all,

Currently my speakers are 12' apart and each speaker is about 10' from my listening position. Picture here: https://imgur.com/a/etiV2q8

Would it make sense for me to move them closer together? (switching with my amp and subwoofer on each side). Curious on thoughts and how people typically space their speakers!

Thanks!

i also wanted to note I added Isoacoustics Gaia II fest which improved the sound. Would switching to spikes on top of Herbie Gliders be a better solution? 
I have a similar room with similar dimensions. When my small maggies are in play they easily move to and from ideal listening locations to more traffic friendly considerations. When I have my big Green Mountain Audios in play (each weighs a hell of a lot) I have them on casters that allow me to role them into listening position and role them back to  accommodate foot traffic and aesthetic considerations. I use almost and equilateral triangle when considering and experimenting in appropriate placement and let my ears do the rest.  
A guy by the name of Jim Smith has been advocating a speaker placement width of ~80% of the distance to the listener.  Works for me.

There is more to it than that as others have mentioned.
