    Re: How am I supposed to lay all this out?

    For an understanding how this build got to where it is now, one must read at least five other strings pertaining to this same project. Here are a few I've come up with, not in any particular order:

    I'll wait to see what you decide to do -- you've been offered a couple of different solutions. I'd take advantage of them first, because even if you manage to get your crossover assembled, you may very well be disappointed with the result.

For a lower tune, a 2"id port, 9" long will get you 44Hz.
    When using a slot port, it is better not to exceed a height to width ratio of 1:8. You may deviate from this a little bit, but the proposed ratio of 1:19 is too high.

    This will be the cabinet I'll be making.

    Here. I will send you the money to cover the parts cost, then pick any one on this forum....ANYONE. send them your parts. If you don't get completed crossovers back keep my money.

    That's how much trust and faith I have in this community. It's probably the ONLY forum I feel that way about.

    Peepaj did the design, and he is a member on this forum.

    xsundown- I told you I would do a layout for you, and I never got a response. Heck- I'll even lay it out on pegboard graphic for you.
    I just need to know which parts exactly that you purchased. Just post the hyphenated part numbers from the order, and I can go from there.

    I also think Ryan would do a fantastic job, and you have nothing to worry about.
    Later,
    Wolf

    You'd be surprised how many of us will help. If I'm going to fiddle with parts on a cross-over board, I like to use Euro-terminal strips to tie the leads together. I get the longest length ones from www.Allelectronic.com I can and cut them up with a hacksaw. Save money... I use low melt hot glue to hold parts down in case I want to change things. The good foam double-stick tape works too. You can do zip-ties like Wolf.

    Just follow the diagram and do each piece one at a time all the way down the line. Baby steps. Before you know it, you'll be kicking yourself for not realizing how easy it is to do.

    Re: How am I supposed to lay all this out?

    If you don't want to take advantage of ROTECH's generous offer of help, I guess that's up to you. I too can understand your reaction, since you're new to the board. But someone with an established reputation on this board, is someone you can trust. If you want to know more about who he is, all you need to do is look up his profile by clicking on his name in the message he sent you. There you will see that he has posted here many times and has been a member for some time.

    If you're still nervous about sending your parts to him, here's the process you'll be involved in:

    It appears to me that you're probably having trouble identifying the parts you have received. I'm guessing that you're having difficulty discerning which parts correlate to the individual parts pictured in the crossover diagram. What I'm talking about is figuring out which part corresponds to R-1, which part corresponds to C-1, C-2, or C-3, etc., etc., in the diagram. If that's a big part of the difficulty you're experiencing, that's the first thing that needs to be clarified.

    That can be done a couple of different ways. I tend to get drawn in to strings like this one because they're rather like working through a puzzle. So, I copied your crossover diagram, and your photo of the parts you have, pasted them in a drawing program I use, and set about labeling them R-1, R-2, etc., etc. I was able to identify many of them, but several do not show the label. Several capacitors are shown label side down; too many to identify by process of elimination.

    I also noticed in your crossover diagram that two different inductors are labeled L-2. I also noticed that the value of several components don't match exactly the values shown in the diagram, but I assume that's because you had to settle for something close.

    Soooo, if you want to go this route, I need to know more about your situation. First, is the problem I described above (identifying the components and labeling them R-1, R-2, etc.) a barrier for you, or do you have that all figured out? Secondly, do you have the means to solder the connections? And third, do you want to proceed?

    Here is a tidbit- I do not know if it is helpful, but it is to me.... I tend to start with putting the negative or ground in the middle of the board and separating the high pass and low pass by that ground.

    Start out with a rectangular crossover long end sideways and draw a line through the middle, that will be your ground or negative path then build the high pass above that line and the low pass below the line.

    once you get the hang of playing with parts and how they relate to a schematic you will be doing well in no time.

    I know it might seem dumb, but here's the image with the grounds removed. For me it helps to lay everything out like this, then everything that "hangs off" of the signal chain goes to ground. looks a little less cluttered.

    + whatever number we're on

    I'm brand new to this and laying out the pieces per the schematic has been a huge help. It took a little time to get comfortable but once I become familiar with the pieces it was all down hill. I spent a fair amount of time studying others' crossovers which helped me a ton.

    Keep at it! It will be worth it when hear them the first time.
