I stuck this in the newbie section nearly a week ago, and havent had a reply i i thought i would try it in here (hope thats ok with the mods ). Ive been trying to firgure out the best way to splay my tops and
the distance to have them apart. Best i found was this
http://bobmccarthy.wordpress.com/2010/03/28/uncoupled-array-design-beginnings-and-endings/
but its not fully sorted it in my head.
I normally either have 1 or 2 void stasys 3 mk1's (Dispersion 45 h 35 v) a side and i would just make a guestimate when spacing them apart and then try and get them sounding as best as i can. I was just wondering if theres any decent reading on this or a good simulation program to help avoid as much comb filtering as possible, help choose a decent distance between the stacks and improve the overall sound and coverage. Hope that is understandable and makes sense. Cheers Matt |

That article is way too advanced for what you need, Horizontal dispersion divided by 2 = splay angle (between two imaginary lines down the centre of each cab, meeting behind them). Simple as. Makes sense when you think about it. 45/2=22.5 so 23 degrees your case. |

Maybe i didnt word my sentences very well. I want to know if you have two stacks what is the distance you want to have between them. I would of assumed there must be an optimum distance depending on the dispersion of the tops and a way to work this out.

Oh I see, sorry!
You shouldn't get much combing, if any, from two sources firing towards each other and crossing (i.e. the inner-most tops on each side) as you said there is an optimum distance between stacks depending on the dispersion of the tops, to minimise the size of the gap or 'dead zone' at the front that is not directly in any speaker's sound field. Don't forget you can compensate with infills if necessary. Basically if you are using one 45 or 50 degree cab per side, the distance between your two stacks should be much closer than if you are using an array with a total dispersion of 90 or 120 degrees. Maybe someone else can provide a more precise technique!

Thats near enough the conclussion i had come to in my head, the smaller
the degree of dispertsion the closer the stacks need to be together.
Infills are good but sometimes they arent pratical. I was just wondering
if there was a calucation/any more reading on this matter. Hopefully someone will be able to point me in the right direction.
Cheers for your replys anyway Corticyte they are much appreciated! Edited by `Matt - 28 December 2011 at 8:47pm |
