    Can the gurus here offer a tip ?


    I'm building a 5 way system.

    Main cabinets contain.
    four ribbon tweeters (2kz - up)
    four 8" midranges (400hz - 2khz)
    two 12 inch midbass (100hz - 400hz)
    one "unknown" woofer (60hz - 100hz)

    Seperate subwoofer box using dual
    or quad blueprint 1803's. (low pass @60hz)

    Those numbers are estimates so you get the idea what
    I want to do or try to do - lol

    What I need is a strong woofer for 60hz - 100hz, I seek what people
    like to call "tight bass". Do you think the Maelstrom is suited for
    this job or is the Maelstrom best used for subwoofer applications only?
    I'm open to suggestion. Some suggested to me to convert my 4 way
    to a 3 way using dual 15" Lambda TD15's.. I have no experience with
    these drivers so I have no opinion.

    I was thinking of using one Maelstrom in a sealed box no bigger than
    5 cubic feet. Sealed box because everyone thinks they sound better
    *and* I don't need the low end frequency extension, the subwoofer
    cabinet will do that.

    If you say "yes, Maelstrom would work", what target Q should
    I use ? ie, WinISD says 3 cubic feet, but I have room for 5.
    Should I go for a lower Q ?

    If you say "no, Maelstrom is not good for my application",
    can you offer a any tips ?

    Thanks,
     
  2. Is your goal just really loud and uncompressed quality music/HT mains?
    If so, how about you get the Unity horn with a set of Got15's?

    You do realize that to make a proper 5 way sound really good is near impossible unless you have some real accurate modeling/measuring software.
     
  3. thought of something else.
    how about getting the Alpha LS's and then use the 1803's at 60hz with a 4th order acoustic XO.

    My goal was not to use horns because of this.

    I want something exotic looking, sounds good.
    Later, I will make something that isn't abnormal - lol

    Alpha LS's are cool.
    But to be honest, I really really love this
    tweeter;
    http://www.stageaccompany.com/cdload.html
    After hearing one of them, I just had to design
    a "mini" line array using them with PHL 2520
    midranges. I have managed to go broke buying
    5 of those tweeters ($600 ea.) and need three more.
    The big mystery is what woofer to use for bass guitar
    playback.
     
  6. If you can twist Steves ear enough to help, his dipoles were a BIG hit at the last SCBL Meeting!
    These should be exotic enough for you [​IMG] They are very complex to build though and require bi-amping.

    actively cross the sub at 60hz like above and you are set!!

    I like it the above system, looks good and
    I can visualize it sounding pretty sweet.
    This is a simple CAD drawing of concept
    I have planned, fully active, 4 way.
    Too complex for it's own good - lol
    It's about 90" tall, just below hitting ceiling - haha!

    Those look like Robocop speakers.

    Yes, the Maelstrom would work in your frequency range that you want it to perform within. I am running a Maelstrom for subwoofer duties and it integrates very easily with the mains.
    I would do a larger sealed enclosure and go for a Q of around 6 for a tight sounding low end.
    Sounds like quite the ambitious project [​IMG]

    free webhosting has it's problems - hehe
    it runs out of daily bandwidth - lol
     
  13. Finally saw them. What type of software are youplanning on using for the XO's?

    you realize that those ribbons will need some major padding down.
