New Line Array Project

Hi Guys..

I am about to start my new build, is for 4 or 8 speakers line array type but i'm just a little in doubt what is better to make it..

To get more spl and sum and align the sound of the boxes what horn is better the pyle nexo clone the dayton wave guide or build the horn with wood in the box i will apreciate the help of the specialistes yours. Thanks

First of all you need to learn the science behind line arrays.

Your choice of hf horns clearly speaks that you have no idea what you are into.

Hi how it goes

You are right I am not a specialist in line arrays, the audio is my hobby but I have read several papers that talk about the beginning of the line array, about 80% of the horizontal space of the box should represent the transducers and also required 4 boxes per side for the physical principle of the line array begins to take effect, which requires a plane wave generator for high frequencies, which is also simpler to make the case for placing the two midbass very together in an asymmetric shape. I was DJ in the 80s and manufactures horns at that time and resume my hobby about 9 years ago and I've made about 40 boxes at that time, several models of speakers for subs and full range. The biggest problem is that here in Venezuela not get the plane wave generators and would be very expensive to achieve. These boxes are for my hobby and would use occasionally for familiy and holidays partys or listen music in my house or for put audio for a small band,

I will accompany these boxes with 4 Turbosound subs and a ALTO MAXIDRIVE 3.4 to adjust and equalize the system. I just hope to try to get the best sound of these boxes with few supplies and resources we have here in Venezuela.

So I would like to know that the horns of the two models will do best considering for not having the plane wave generator

They are also available for using these two models of horns:

Thanks I will appreciate it your help

Yes thanks you very much and I saw the wood design with the two drivers eminence, you showed me, i will made that model exactly if i have the appropriate measures for a box using midbass 8 ".

Llet me show someting that i was work thinking in that

I don't know if you actually know anything about wave guides at all, but that isn't how a waveguide was supposed to work. In your drawing there is absolutely no function to the fins.

The fins are supposed to time allign all the waves running through each individual channel creating a uniform wave front.

like this:

Or something which is easier but which math says works as well (the main flare being a parabole)
