Re: Subwoofer Build -- 12" Dayton DVC

That is the one that I was looking at that is currently out of stock. Looks like they are supposed to have some in a couple weeks though.

I think you'll be happy with this design -- I was, and so is my daughter who uses it in her Tritrix 5.1 system. Considering the cost, I was very, very, impressed.

Parts Express has drastically reduced their stock of shielded drivers in the past few months. With the advent of non-CRT type displays, there isn't munch demand for non-shielded drivers. However, they do offer what appears to be the same driver without shielding. I haven't compared the TS parameters but, I don't expect there would be any significant difference. It is a very popular driver...

Nice build. I may copy your design for a sub to match up to my Tritrix build. Unfortunately, it looks like the driver you used is not in stock. I hope it wasn't discontinued.

Yeah my father-in-law used to own a bodyshop as well as painted for 30+ years, and recommended I do my ranger's bumper with laquer, boy was I in over my head lol. another reason why it didn't turn out haha.

Lacquer used to be the gold standard for car paint jobs. A good skilled painter could turn out beautiful finishes with lacquer, but it's pretty labor intensive. If I recall correctly, lots of custom finishes took 15 or 20 coats, followed by "rubbing it out," as they used to say. Lacquer would likely be one of the most difficult to apply when it's hot, because it's fast drying to begin with, even in low temperatures. I'd like to try it on speakers... I'll bet yours turned out great...

Re: Subwoofer Build -- 12" Dayton DVC

Your sub project turned out very well. I've had my own troubles painting high gloss stuff in high heat. Most recently a sub baffle that just wouldn't paint right. I was shooting it in my parents garage in 90+ deg. heat & humidity. After awhile, after noticing it was going badly, I just kept on spraying layers and ended up sanding and compounding it smoothly once it eventually dried. I was using black lacquer by the way.

All's well that ends well.
Nice job.

Re: Subwoofer Build -- 12" Dayton DVC

Thanks -- it turned out pretty well. I've painted a lot of things with spray cans, and gotten good results. But, having spray equipment is great. I find I use the smaller guns, as often as anything else. But the overspray is the biggest challenge. Indoors, one would really need to construct a spray booth with ventilation, and a filter on the outflow side to trap the overspray. Exhausting to the outside, of course. That's probably what I need to do, but for now, it's outside. Going to Tucson?

Re: Subwoofer Build -- 12" Dayton DVC

Nice paint job! You would think the heat would make paint dry faster, but for some reason it's just the opposite. I've managed to get a hold of a single room air conditioner for the garage, it's made summertime painting projects much easier. Some nice spray equipment would be nice to have, but for now, it's just rattle cans for me.

Thanks for the good advice, and thanks for the compliment...

Re: Subwoofer Build -- 12" Dayton DVC

I think your point is that the potential health risks of these products warrant minimizing exposure. I would certainly agree with that. As for the supplied air respirator, I would agree that they are superior. But a brief Internet search shows that one can expect to pay somewhere around $2,300 for a pump, hose, and mask. That's a bit pricey, unless you're going to use it quite a bit -- especially when BASF's safety data sheet says that a half-face respirator is adequate, assuming you have good ventilation. Painting outdoors should satisfy the ventilation requirement, but I usually also have a fan operating whenever I'm going to be exposed to anything, including sawdust. I absolutely hate breathing anything potentially harmful. Thanks for the reminder...

Agreed. The respirator is going to handle the particulate, and fumes...but nothing will "filter" out the iso's. There are definitely more economical solutions to fresh air. Some can filter your compressor air, "Tee" off at your supply hose, one to the gun, and one to a hood...The air from the compressor has to be tested, and a contamination "detector" placed inline. For the most part, the amount of refinish work done for a set of speakers, and the frequency that most builder's here are going to paint...there is not going to be a "danger"...but if you have little ones at home, and you are painting in the garage...you need to be aware of the dangers...
I am amazed that you got as nice of a quality job painting outside... I did mean to point that out...I have followed both your builds and am very impressed.

The odor with 2k products is not the issue at hand...do some research on isocyanates. I painted cars for 20+ years. You endanger yourself (possibly your family) if you are painting in an enclosed area, little to no ventilation, a respirator will not do the job. Fresh Air Systems are the only answer to iso's...

Re: Subwoofer Build -- 12" Dayton DVC

that is most impressive then.. the place i saw has it listed at $49 a qt. But $35 is not bad if thats how it ends up. Did you have a respirator? how was the odor from that 2k?

im wondering how it will hold up to mdf expansion, let us know in a month or 2 if you see any lines.

After rereading your post, I did an online search for Limco Urethane. I came up with the following link which may be the same place you looked. But it appears that the cost is $49 for a gallon, which is substantially less than what I paid. It doesn't say that the reducer and hardener is included in the price, so I'm going to guess it isn't. That might raise the cost considerably, but I'll do some more checking. You could do a lot of speaker painting with a gallon.

I do have a respirator, which I wear if I think I'm going to have any real exposure to the airborne solvents. In this case though, I painted outdoors and it was a small project, so I didn't bother. It's a good idea to use one however -- I should say, it's a bad idea not to use one.

The odor wasn't a problem.

Re: you've got a PM

it Is A Bit Expensive, But Not Too Bad When You Consider What The Standard Home Center Stuff Costs. I Paid About $35 For The Quart, But I've Got Enough Left For Another Project. I'll Be Spraying It On A Couple Pairs Of Overnight Sensations I Am Building Currently. The Finish You See Is What Resulted From One Coat -- I Didn't Use Any Clear Coat, And There Was No Polishing Involved. It Really Performs Well, And It's Much Tougher Than The Enamels You Get From The Home Improvement Stores.

I Think I'll Be Able To Buy Automotive Urethane Paints Through The Internet And Further Reduce The Cost.
