DR200 (x4) Build Thread

Primer is 1/3 the price of Duratex.

Got all the metal attached on the backs. This is my first time working with metal and PL. I've come to the conclusion that I don't trust the strength of the PL-to-metal bond that much. However, since there's probably about 50-60 staples in each cab holding those metal sheets in place, I think it will be alright. The PL is enough to keep it airtight, and the staples make sure everything stays in place.



I also got the insides coated before moving on the the side panels. Duratex on flat black latex (although you can't really see it in the lousy cell phone pic).



I'm getting nervous about my supply of Duratex. If I'm lucky, I might have enough left to finish these babies off. But since I still have to do the outsides plus the insides of the side panels, I'm afraid I'm going to be just a wee bit short. I hate to get another gallon right now when I'd barely crack it open and then put it right back on the shelf for who knows how long. Sure wish they sold Duratex in pint size containers.

Although it looks great, I'm not sure why many do the insides and less visible parts with duratex. Why not just do the outsides?

I can't speak for others, but for me it's about the consistent appearance. In my opinion, it would look bad to have the outside have one finish/texture, and the clearly visible area toward the front of the mouth look totally different. I guess if I wanted to spend the money for something more than flat black latex paint, I could make the insides look nice, but, if I'm going to be spending extra money on some other type of finish, I may as well just use the Duratex.

Another option is a full grill on the front to hide the insides altogether, but Duratex all around is still the most economical of the options that are acceptable to me personally.

They look fricken good buddy!

Betcha can't wait to get them done and plugem in.


I agree duretex company would make a killing off people like us if they sold in smaller containers.

Maybe you could paint the internals like the DR250 of Tim A!!

Had a couple of busy days, so I didn't get much done, but last night I got the side panels rough cut, and this morning I dry fit them with screws. I hope to go over them with the router and a flush trim bit this afternoon to get the edges flush with the top and bottom panels. Then I'll trim them to length on the back end, remove them and sand and paint the inside face before attaching them permanently.

Working from home today, so during my lunch break I ran out to the garage and trimmed the sides. I love it when the sides go on. That's when it really starts to feel like you're getting somewhere!

Whoa , nice little saw there!

[David Carter]

Whoa , nice little saw there!

Thanks. I got it for cutting out sections of drywall when I did a bunch of rewiring after moving into this house that was built in 1960, but it has come in handy on my latest BFM builds. As you can see in the pic, I built myself a little sled for it which lets me use it for all the cuts where I normally would have had to drag out the regular circular saw. It's been absolutely fabulous for doing plunge cuts for access covers and the like!

This is where I got it.

Well they do look great, and they look like they're ready to scream stacked and arrayed like that.

[David Carter]

Been slow going lately, but I've got two of the boxes Duratex-ed with corners and speakon jacks installed. I'll take some close-ups later on. This morning I wired up the one melded array I've built so far in order to test my high pass filters. I was nervous going into the test because of the problems Scott had with his after following my wiring diagram. It turned out OK, however. I ran a signal through the array with no filter and then I wired it through the filter, and everything worked! I still have to test my other filters, but the first one worked fine.



This close-up exaggerates many of the imperfections due to dust and lighting, but as you can tell, my array is not perfect. But at this point, I don't have the patience to do any more work on it, so it's staying like it is. Fortunately, it doesn't look as bad from a few feet away.

Nice job, David! Just think of the sound system your going to have for years and years when completed. WOW!

I wouldn't worry too much.
There are a lot of things that look good from a distance!
