    Re: The Small Stack; a Micro 3-way.

    I meant from bottom left to top right slant.
    It smooths out the baffle diffraction loss.

      Oh, align the drivers in a slant up the baffle. Got you.

      I can't use the program. :( Anyone want to guide me in installing one of those programs that lets me run windows based programs on a mac?

        Think I got it....using Parallels for Desktop 9.

        EDIT: nevermind. Still need help. Need a copy of windows. :p

          Fuzz measure looks like I can get a few graphs right off the computer for rough measurements. I'm sure the mic isn't fantastic but I think I'll play with it a bit to get the gist of how this all works before the drivers get here.

            That makes sense once you get past 112 and 123. The Fibonacci sequence then begins to converge the Golden Ratio.

              What benefit does off setting the tweeter and/or mid serve? I know the gradual slant could help with time alignment, but how much slant?
              To accurately align the drives acoustic centers you would need to measure on a flat test baffle first to get the acoustic offsets. However, you could probably just estimate that for a 4" driver and tweeter you would need the tweeter about 3/4-1" offset behind the face of the woofer. With your close spacing, I think that would need to be a pretty large angle though. I wouldn't worry about it too much. By using asymmetrical slopes you can get phase alignment. It just makes things easier by physically aligning them.

                Re: The Small Stack; a Micro 3-way.

                When you say offset, are you saying in the z-axis, or tipped back 3/4"?

                On the fuzzmeasure(FM)/laptop mic note, it's surprisingly in the ballpark of expected measurement. The measurements my AVR is posting are lining up very closely to what FM is showing me. My AVR is boosting through the roof the 300Hz range and FM is showing a major suckout there. There is also another dramatic dip higher up and my AVR is boosting in that general region.

                I'm still going to purchase a mic, but jsut nice to see I can get a fairly accurate measurement with just my laptop.

                Any recommendations on a mic?

                  The Dayton version of the Behringer mic is just fine. It comes with a cal file too.

                    PCD calculates z-offset in the forward and backward direction, so you would be setting the tweeter backward -3/4" to -1" to line up the centers.

                    I've been looking. At picking up the omni-mic package so I might be willing to sell you my rig if you are interested.

                    The only issue with measuring in Mac OS is that you still have nothing to model with. You will need to save the files and copy them to a windows operating system to be able to use them.

                      Is that the Dayton USB mic? I was looking at that or the em8000 or hat ever it is....

                      Lmk about the rig.

                      Setting the tweet back is no issue.

                      I'll have to get my PC up and running.....

                        UMM6 is the USB version and EMM6 is the regular version. If you don't already have a USB mic preamp then the UMM6 is probably easier.

                          Yeah just grab the USB mic, so you don't have to fool with another piece of equipment.

                            Is there any or that much difference between the ECM8000 and UMM6?

                            Kerry offered a full setup sans the XLR cable for a little less than the price of the UMM6. I do like the idea of just plugging the mic in to my laptop and going though, but I know nothing about this mic business.

                              I'm going to be ordering the drivers for this today. Are there any other parts I can order now that you can foresee me needing (crossover parts, anything to help with mesuring, etc)?

                                You might want to pick up a DATS. You won't really know what crossover parts you will need until you get measurements though. I can't really think of anything else you would need right now.
