yea if it's not baltic birch then it's going to be different so it would be pointless.

Made a ton of progress today. I built and tested one of the crossovers and it worked! Can't believe it. I found a picture of the layout that I used on line and realized that I had no idea where the connections were supposed to go. This was a blessing in disguise because it forced me to look at the original crossover layout and actually understand it. I couldn't believe it when I tested it and I heard "Evangeline" by the Band. I was unbelievably revealed.

As for the finish, it was a bit of a journey. I started out trying to get it to look like another OS build that used Ebony stain from Minwax. His looked fantastic, but I applied a few coats to the back of back of the speaker and I did not like the result at all. I then contemplated veneer, but settled on Red Mahogany and I am very pleased with the results. Tomorrow I have to stain the bottom of the speakers and add the clear gloss and I'll be ready to finish on Sunday.

A couple of questions:

1. How do you guys hold the port tube in place. My understanding is that it should be 6 inches. I have seen speaker sealing caulk, crazy glue and tight bond. I have tightbond III, would that work?

2. I just assumed that I should drill holes for the screws, but it looks like some people just screwed them in with no holes. If I should drill holes, does anyone know what drill bit I should use (I told you that I was a total noob at this!)?

I tried to post a few pics but they were too large and I have to figure out how to resize them.

Thanks for the help!

I've just used tape on those adjustable ports, quick, easy, holds fine and no mess.

A 7/64" drill bit usually works well enough for both #6 and #8 size screws, it's what I use for my pilot holes.

Thanks, mtg90! I am assuming that when you say tape you mean duct tape?

Yeah duct tape will work great, so will electrical tape. I used clear packing tape once and that worked as well.

Well, it's so humid here that the stain that I did 20 hours ago is still a bit sticky so I'm afraid to put the Polly on. Looks like I won't be finished tomorrow. Stain looks good, though.

I finally finished the second crossover and tested it and it worked. I'm pretty happy as that part was my biggest worry. Tomorrow I'll finish up the housings and hopefully complete the whole thing on Monday but more likely Tuesday. Here are some pictures:

The crossover before I glued and soldered it:


The housing after glue set:


The housing stained but not finished:



The crossovers:

Finished stain and hopefully will be listening to them tonight. Quick (and probably stupid) question, the tweeter uses reverse polarity. So that means hooking up the positive wire from the crossover to the negative input on the tweeter itself? Thanks!

Yep, as long as that's what the design calls for, you simply hook it up in reverse like you described.

Finished! These really do sound great. As others have said, the bass is really incredible for heir size. I'm really impressed with them. I have listened to a few tracks from the last waltz and I'm currently watching a blu ray and these handled both of hem very well. I'll post some pics later.

This was a great project for me, I learned several new skills that will help me down the line with other projects down the line. My one problem is that I'm now hooked on DIY. I can't wait until my next project.

Thanks to everyone that offered advice and suggestions, I wouldn't have been able to do it without all of the help.
