    Bad Line Array Designs

    I feel your pain if you hate line arrays considering so many bad designs on the market that don't really show you what they are capable of. Not your fault you hate them, you never experienced a good one.


    ** bad designs **
    Here is two new ones on the market.

    Re: Bad Line Array Designs

    So basically, besides the directivity issues what makes you say these are bad line array designs?

    What do you think of these?

    http://aca.gr/pop_skal.htm

    And what would make them good or bad?

    Each one has it's own issues.

    I see a loudspeaker, but it's not worthy of being called a line array by modern
    expectations. lol

    Nothing wrong with this automobile, but c'mon, you can make one better
    DIY one. http://www.uh.edu/engines/model-t.gif

    I really don't know why certain manufacturers make such crummy designs.

    Re: Bad Line Array Designs

    That first one is just stupid. I thought one of the biggest rules when doing a line was to keep the drivers as close as physically possible for coupling? That Gallo makes no effort in doing so.

    Re: Bad Line Array Designs

    all the good line arrays i have seen on this site thus far have been made out of cheap wood. judging by the materials used in the products linked i the thread. these all must be over priced pieces of ****. i have read consumer reports guys, i know what i'm talking about.

    Hahahha....

    That was funny...

    Anyway, I want to know what EXACTLY is not good about them. I always have to justify what I say on this forum so I want to know! I don't get how you can judge a loudspeaker by looking at it either...

    The first one I already explained why it is a poor design. The others I have no clue why they are no good. We will have to wait for the resident expert on line arrays to tell us why.

    See, what can you tell from the picture? I can't really tell anything, maybe he used the distance as a phase coupling advantage. Who knows, I am sure there is a reason for what he did. Don't you think?

    Put it next to some good speakers and pretend you are listening to a line array?

    Re: Bad Line Array Designs

    Problems with this one.
    http://blog.stereophile.com/ces2007/011207shin/

    Tweeters and midrange alternate. It would be much better to move
    all the same drivers to one contiguous line; ie all midwoofers on the left,
    all tweeter on the right of the baffle with low midrange CTC spacing.

    8 4" midranges is a joke. You need 16.
    7 tweeters isn't enough, you need to double up.

    "The 5LS has no crossover other than a first-order low-pass filter and can be bi- or tri-amped, although "any capably designed amplifier can drive them."

    Do they not know how to make a crossover?

    "Twelve rear-firing 4" subwoofer drivers"

    You don't want to integrate a subwoofer into your mains.
    It's best to have a seperate sub.

    Everything about it is bad. This design is something the 6th grade kids
    did for a science fair project. Something neat that kids made, but complete wrong in design.

    ************************************************** ************

    From this you can probably analyze the other bad designs.
