why will it sound shit? I believe if a single box will sound good..then it can be arrayed..with proper eq, DSP and delay settings including good sub's ..I think it can't be far from the real stuff

What you think and what happens in reality are 2 different things. If you look for a white paper by some small guy from L-acoustics who explains how line arrays work, you'll find out that this box hasn't got anything right.

It's
vastly different. I and many others don't pontificate on matters about
which we know nothing, and nor do we give out incorrect advice. It's a big deal because some inexperienced newbie visiting here might use some of his ill-informed advice. Generally I do ignore his posts (or laugh unbelievingly at things like his plastic mouldings) but in the last few days he has constantly posted innacuracies; viz. his notion (in the PKN H8 thread) that you can only use active boxes over short distance unless you have a very capable mixer.

HF dispersion. There's one. There's one reason it won't work. Rather then this barrage of f##king nonsense I thought maybe giving you one good reason it won't work would be a good start. |

you would probably be better off with a different system unless you are doing very large venues or outdoor events. if you really want a line array just buy a second hand one. if you had the experience to run a line array you would already know this though without having to ask this forum. I say this as someone who has never operated a line array - but I realise what I don't know. there are others on here with a lot more knowledge than me telling you the same.

rayrainx: both Pasi and I have said the same thing although he was a little nicer than me. This is a box built by someone who knows what a line array looks like, and not how it works. Likewise even for some commercial products to be honest. Go read the FULL VDOSC manual and whitepapers. Run some mock simulations in their free software. Go work some shows for free as a box shifter and ask questions afterwards, politely, about the deployment. Then think about maybe building a few boxes for fun, to experiment. But don’t think you’re remotely close to the real thing by downloading some point source box plans with the HF horn made narrow on one axis and rotated by 90 degrees. |

This thread reminds me of the heated internet discussions that were going on 20 years ago, when calling something a "line array" had become the new way for manufacturers to persuade unsuspecting customers to buy their speaker systems...
The term "line array" has no scientifically defined meaning and therefore it can mean whatever you, or a manufacturer, wants it to. A bunch of speakers laid out in a line. On the other hand, the term "line source" does have a specific meaning, as defined in any good book on acoustics. With considerable R&D effort, it is possible to make something that has many of the attributes of a Line Source over some (or even most) of its frequency range. The most successful of these are the ones with full DSP control and amplification integrated into the speaker cabinets. MLA and Anya, for example, are line array systems with highly optimised alignment that gets them close to line source behaviour. They also have further facilities to divide the array into sections and break up the coverage pattern into more than one beam. The manufacturers of these are careful to avoid calling them "line arrays" but this is for reasons of market differentiation - they have taken the concept a lot further and are so much better than what the term usually implies.
This is usually not correct. All through the 1980's, manufacturers and their marketing departments persuaded customers to buy "one box" systems on this basis. Some sounded lovely in isolation, but none of them worked properly when combined in large quantities. A typical large festival system only sounded good at the mixing desk, which of course is not where most of the audience are. But it is where the FOH engineer and management listen to the show from, and they are the ones who hire the sound company... Due to the size and shape of the audience areas at most large-scale events (you need to consider these as if viewed by the loudspeakers) it is easier to mitigate the ill effects of combining multiple speakers by designing systems that work better when stacked vertically. Doing this also makes it easier to design systems that can be flown from a minimum number of suspension points, which drastically reduces the time and cost of installation and de-rig. So the old One Box systems gradually got replaced with vertically arrayable cabinets, which everyone called "line arrays", some of which worked better than others in terms of acoustic design. If you want to design a tall thin column speaker that has some attributes of a line source, you need to design the whole column first, then break it up into modules that are easy to transport, handle, and connect together. Having done this properly, the individual box probably won't sound very good on its own... As has been mentioned, the V-dosc was a complete concept - including full system design, training, and user certification. The user and training manuals were particularly good (by Paul Bauman, I think?), as was the training course, and contributed greatly to its success. It was the first modular line array system of its type and was very well designed for its time. |

How very dare he; that's MY fooking job. I feel the need to find a socapex and shove it where the sun don't shine...and not one of his efin' SELV DMX ones; one running 6 channels of dimmer up it, at full brightness, over 3 phases, with all earths and RCDs removed. Jog on with your baseless "I read it on Wikipedia" statements that you are trying to pass as fact. One of these days, your keyboard diarrhoea will cause someone to either loose a lot of time, money, or, when fecking with significant power, maybe worse. FFS |
