I recently picked up a set of subs and tossed them on a stained redwood cabinet in the house and thought it looked great :)

Just curious, but has anyone ever tried staining raw MDF :confused:

you can buy veneer and cover the mdf.

worthless. the hole reason to stain wood is to help bring out the grain of the wood. mdf has no grain. NOW, if it was the nice birtch ply, i'd say hell yea stain it.

if u do a good job with the primer though, paint will look really good on mdf. u might try that as something different.

I have stained it before and it didn't look bad at all. I used a dark walnut color and I was actually surprised by the results. A lighter color would look pretty lame though but the dark color kind of gives it a neat texture that doesn't look like a bunch of sawdust even though that's kind of what you would expect it to look like.

Yes, but not on this computer. I'll try to get some when I get home. If not, I'll grab some pictures this weekend and PM them to you.

cool. i have an a$$ load of cheery veneer from when i worked in a veneer factory i was goin to put on my next box and stain it. i think it would look sweet with the C/F cone on the DMX's. :D

i've stained it in the dip table that i made (my ava). just used some pre-stain conditioner and about 5 coats. looks pretty **** good. used a gun-stock color, kinda mahogany looking

I have stained it as well out of curiosity of the results. Like Imma, I used a darker stain, roughly 2 coats. It really didn't look too bad. IIRC the edges will stain a bit darker than the face. I'll take some pics if I can get around to it.

miter joint your bow to get rid of discoloration. the end grain(would you call it that with mdf) is always more absorbant. typically needs more coats of finish too

Immacomputer

Yep, the end grain did soak up the stain and polyurethane like crazy but I found if you let about two coats of polyurethane sit on it and dry, you can sand it and it will not absorb it as bad. After sanding once or twice, it takes the polyurethane just fine.

Here are some ****** pictures I have of what I did:

If anybody wants, I'll get some better pictures this weekend.

Oh, giving it an uneven stain job almost makes it look like wood grain. I noticed this on a test piece I had but didn't do it on the enclosure as I didn't want it to look like wood grain.

Your results are better than I expected. Always thought mdf will soak the stain/paint like a sponge so coverage will be a chore. But I guess the prime coat will seal it. Although, I wouldn't attempt it! I treat my boxes rough, so it'll be scratched up before it's even in the car.

Mine got roughed up as well and you can see it in the pictures. I usually keep my mountain bike in my car and it sits right up against the enclosure. I really did that enclosure that way because I have had multiple enclosures fail due to water damage and I had not located the leak at that point. The stain and polyurethane worked really well to protect it.

The MDF really did soak up the stain and it was pretty ridiculous at first. I didn't prime the wood at all and just used a bristle brush to apply the stain. The brush gave it a streaked look as well but I prefer my stain sponge for anything with real grain.

Side firing port? The enclosure looks pretty big. I like how well the rounded edges came out. If I were to do it, the edges of the box will probably eat that stain up. Unless, I use wood filler to stop it from seeping into the pores.

You could use wood filler but it stains differently than the wood. The best way to keep the grain from looking ridiculous is to lightly sand it and then put a few coats of polyurethane on it and then sand some more after a few coats. After that, you should be fine.

I've seen those, but they only have certain colors. Also, I didn't want to chance the veneer falling off when I cut the wood.
