Please somebody advice me.. Are these line array plans a GO. or is it just a bunch of crap? Happens to be the only available line array plan on the internet I have seen on sale.

That is not a line array it just sorta looks like one. The real magic of a line array happens in the DSP processing and even then only when every single driver is on it's own amp channel and the boxes are designed to work correctly in a column. You will get none of that with the above plans, yes it will make a bunch of noise but there won't be any control over it.

Build a point source if you need one. Buy a line array IF you really, actually can prove you need one.

That means a show of over 2000 capacity, with the ability to fly it. After you’ve done the training, research and worked on some other shows using one.

A line array is not just a vertical hang of boxes, it’s the entire deployment from pre show design to hang to verification alignment and tuning. Its as simple as that really.


Oh and the thing you posted, is good for firewood. No data, no dice. Besides, the tech is over 20 years old at this point. You can buy a better box than that with a known badge, known data, known presets, and support for less than the cost of building and designing one.

That´s more or less what Conanski said! So why call his post horse crap?  Confused

Because they’re not the same thing at all. I didn’t claim there’s magic DSP - quote the opposite for a good sounding hang - nor that it only works when every driver has its own amp channel and DSP. If that was the case then for L’Acoustics don’t make a line array and they bloody invented the things! At that point it isn’t really a line array anymore and you can clearly see that in the MLA marketing and training.

Ok, understand - but without the appropriate DSP (and setup) 'line arrays' are just a bunch of boxes making a load of noise...

Technically, so is any speaker...

The training and deployment is what makes a line array work. There’s a reason the old VDOSC manual was over 400 pages long and had a LOT of theory. Sure, the big boys have software tools to save time with that and I believe too many people with line arrays out there are just operators and not engineers now, but that’s a privilege that cash reserves and doing it for ages affords. A beginner would still need to do enough theory to make a workable design let alone actually hang it and make it sound good.

The VDOSC manual even reminds you that you don’t get a ‘line array’ effect for the full range of the box and that the stated nominal dispersion is actually different on the main frequencies of interest. Funny what manufacturers won’t say, these days.

Dig that manual up, it’s a quick google and great reading. Mandatory for anybody thinking about building rather than buying.
