I you are using a highly exothermic epoxy I suggest mixing smaller batches or in a much larger container. With a larger container (i.e. thin layer across a large surface vs. a grouped mass in a cup) the additive heat is less and will help mitigate excessive heat from the corresponding reaction and early set of the resin.


Clinton,

Where's the basecoat and first candy coats already. Your layered finish is going to look sweet, the more pearlesence the better



Edit: For those looking to spray a finish buy the best paint gun your compressor can handle fi your time is valuable, you will thank yourself later when you realize how much less inter-sanding and finish work you have to do when your "Off the Gun (OTG)" finish is nice and smooth. I think the biggest issue is that many buy HVLP guns and don't have the CFM to properly atomize the coating, as well as the fact that many of these "quasi hvlp" guns you find at your local big box have oversized fluid passage so that nearly any coating will flow, yet they cannot properly atomize even a mid viscosity paint. Therefore I suggest for many to purchase a good conventional sprayer, it has a much higher pressure at the aircap over HVLP and therefore can better atomize more viscous coatings.

INVEST in your finish system, if your time is important to you of course. It will save you a $h!tload of hours sanding, rubbing out, polishing, etc. in the long run.

Had a little misshap last night so it will be a day or two longer than I was shooting for. That enclosure is pretty heavy when it stats falling. Just checked it weights 85lbs right now no driver.

I had some issues with trying to move some of my pics around and deleted an album so most of the links are messed right now. I'm going to try and fix em but here's a link to the pics if anyone wants to have a look before I fix emHere they are.

And an update.
Got the primer sanded, had a misshap so I had to fix some stuff and reprime.
All sanded down with 600grit wet and ready to spray.





First 2 pics are the charcoal base the next two are with 5 coats of cherry candy.






And the first 4 coats of clear, it's not as smooth as it will be since candy doesn't generally lay down perfectly smooth it takes a few coats to fill. This will be sanded with 1000 grit wet in the next few days and maybe a few more coats of candy then 4 more coats of clear.

Without a doubt, one of the finest looking subs that I've ever seen! I heard a version of that driver at a P.S.A.C.S. stereo club meeting, with two 15" passives. I think you are about to put many of the $5K subs to shame. Really nice work. How did you seal the MDF? I wound up putting about ten coats of primer over a small satellite pair that I made. That stuff sucks up paint like a vacuum cleaner. LOL

Clinton, your work is incredible, and going by your other projects, it's pretty obvious that your an artist.

This subwoofer is turning out great. The shape, the color, the whole thing, it just looks great.

Very impressive stuff and I can't wait to see it all come together.

Wow, that looks good.

The craftsmanship in the DIY forum has taken some huge leaps in the last few years and Clinton's work is just adding to that level.

Happy to see you sharing your experience on the forum Clinton, very educational.

Thanks, not sure about being better than a $5K sub but for the $950 I'll have into it it should be pretty good. I used filler to seal alot of it off, just a lite coat over most of it. What wasn't covered (top,bottom, front) sealed off in one coat. I put 3 coats of high build primer on to fill/seal. Everything that I have used has been automotive grade so filling sealing and finish should be pretty high quality.

Thank you very much, after looking at your build I wish I had went a different way with my build. I have a shadow box as well around my screen just not made of subs. Not much of an artist just a bodyman so this is pretty much what I do.

Oh and got it all sanded down for the next 4 coats of clear. Also remembered I didn't recess the magnets in for the grill so I drilled the holes real careful like and epoxied some magnets in.

I know this is getting a bit repetitive but I wanted to show what the actual colour was that I ended up with, moved it ou in the sun for a true colour showing. Mind you this is my phone camera, but fairly close to what I'm seeing. Four more coats of deep red candy and 4 more coats of clear, I'll end up polishing the enclosure after all. That's what happens when you paint in a really low air flow garage.
Next pics will be with the driver in and ready to make some noise I promise.

Thanks for the great comments guys.
Spent a few hours sanding the whole thing down to 2000grit and polishing it up last night. Put the terminals in stuffed it (3lbs of poly) and just about broke a knuckle getting the driver in place, man it's heavy no idea how you guys with larger heavier drivers manage it 42lbs is the limit for my digits. I'll be building a grill of some sort but it'll have to wait for a bit as Halloween is coming and I'm behind on some castings.
Want to thank some of the guys that I bothered during this build without em I'm sure this would have be an epic fail.
LTD02, Ricci, Penngray and Warpdrv, your all a great bunch and totally helpful. Glad your all willing to share your knowledge so pain in the a$$'s like me can get a great build with a little confidence that it will turn out right.
Anyway here it is all finished off driver in and back in it's natural habitat. It doesn't sound a whole lot different than the test box other than not being able to hear the box vibrating and dancing across the floor. This box has almost zero movement during the loudest/lowest movie passages my amp will allow me to play. I def need a bigger amp now driver is great and the amp just tanks.

Hard to get really good pics in a dark basement but here's the best I could get.

your work is crazy off the charts.

crediting me in any way for your work is not fair...all the credit is yours.

your sub looks so good, i'd put a street price on it of $4-$5k+.

pic 3 in post 77 looks like a commercial shot that belongs in a high end av/rag.

yours is among the best finished subs that i have ever seen. no b.s. very nice work.

I'm with the other 2 comments above.

That's 1 high class sub and definitely one of the top builds, probably the best paint job I have seen on here.

Thank you for sharing.

What a job with the finish. One good thing about the Tc drivers is that any of their 15's will drop in with the same bolt pattern. I think it needs a twin down the road.

Um ok, pics in the first post of this thread. I will stand behind what I said in my private message, it has a decent finish and nice shape. But i thought with all the stressing with well made well braced it would better or deeper for some reason. Now i know like i said I guess a box is a box no matter how its built as long as It's not flexing It's to sound pretty much the same.

That just makes too much sense, it can't be true.

Yeah no idea what i was thinking, guess i wasnt.
I did bump the volume and stuff it but i guess 2 exrta cubes to driver like this doesn't gi far. Next time It'll be a pair of 15's or 18's so i can get the level I'd like.

I keep wondering what that sub would look like if you were in fact "good" at woodworking skills.

BTW, that sub looks VERY lonely over there. Almost as if it needs a partner on the other side...

ClintonH, keep an eye on Ebay, once in a while, you'll find a used LMS 15" sub for sale if you're looking for a second sub. About three months ago or so, I found one on Ebay and bought it at a good price.

Sorry meant to say thanks guys for the great comments. I am very happy with the fit and finish the enclosure turned out with, and it's very solid doesn't make a move even at max volume. Tested it with old wine glass with water on top deal.

But I have to ask cause you guys keep asking about a second one.
This is a prototype LMS driver, the specs I got read different from any of the other 15" TC drivers I can find. Can I use any other LMS driver along with it? Or does it need to be this exact same driver/specs to work proper? I've seen a few LMS driver floating around but not this exact same one.
