    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 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.

    That should be close enough.

    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.

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

    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 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.

    Thank you both.

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

    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. .

    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.

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.
