The modeled response was 1 db down at 80Hz and 1 db up at 58Hz. When I listened to the speaker, I liked a port length of 5.5 inches best, but the differences between 6", 5.5" and 5" were very subtle.
    Thank you DrJay! Much appreciated.

      I have been waiting for the tweeters to get back in stock. Now they are so I ordered everything today. Can’t wait to get it.

        I have been side tracked but I have these in the works. I have to finish the front and rear baffles (cut holes and finish). If I manage to cut well I am going to use a Corian baffle in the front. I get cheap scraps locally so why not.

        I did have a quick question… The tabs on the tweeter are tiny. Do they make connector in this size or should I just solder to the tab?

          I measured the tabs on the Tweeter and they are a strong. 1/8 inch So a 1/8 inch connector. Does not fit. You should be able to find something that does though. .

            Solder, but do it carefully. There is not a fast-on for that terminal.

              If there is room for a small tweezer like heatsink, then it should be used during soldering.

              I have a fast on connector that is slightly oversized. It grips solidly but is slightly wider than what is desirable. Considering the vibration it will endure, Ben's soldering suggestion is likely the best solution.

                Use clip on heat sink(s) if you have them.

              If I get some time this weekend I am going mount the drivers to the baffle. I have yet to cut the holes. As far as the driver centers I didn’t see any of those details. But it looks like the tweeter is only set down as much as necessary and the t/w spacing is at a min as well. So I will just do the same unless there is more specific information available.

              I have the tweet 1.5” from the top of the box and in this image the tweeter and woofer are 0.5” from each other. It looks like I should reduce the tweeter to woofer spacing.

              Thoughts?

                I would probably move them closer together to try and mimic Duane's spacing.

              Thank you Jeff. I am going to halve the distance that you see here. It am going to try 1/4” spacing. That baffle is corian which is a little more brittle so I am hesitant to take too much material out between them in fear of it cracking.

                That should be close enough.

              I have my set complete. I will create a gallery for them. Unfortunately, one of the tweeters has a vibration. I contacted customer service but they look to be out of stock for another month.

                  Thank you so much Tom! Just for the record, Tom is an awesome guy!

                  I played around with it more and I figured out that it is the woofer that is bad rather than the tweeter. Of course they are out of stock too. They are a popular little driver!

                  I created a thread with a couple of pictures as well.

                  Thank you everyone for all of the help. I could not have done it without the advice you have all graciously offered.

                    I know this is an old thread, but can someone reccommened a PVC counter part size to the port in the parts list. I already have several sizes, and wouldn't mind saving the $$.

                      Looks like 1.25" i.d. I usually take a tape measure to the local hardware store. If you cannot find the size you're looking for in pvc, try the cpvc, or grey electrical conduit. All kinds of good stuff at the hardware store.

                        Yup, 1-1/4"id x 7" should mimic the tuning (in 0.18cf).
                        I'm using that 115-4 w/a 1.25" x 10" long (vertical) port, but in a box half the size (0.10cf gross, 0.09cf net).
