going to build a box for my sub any tips or tricks?

I'm going to build a ported box for my sub it looks hard but I'm going to give it a try anything I should know before I start?

I was going to glue and screw it to gether and use something like calking to seal all the seams.

Also instead of making the speaker wire connector thing I was just going to route the speaker wire out the port to save some work.

this is the box I want to try to build http://www.diamondaudio.com/PDF/curr...dEnclosure.pdf

Good luck. Glad your going with that one. It should sound great. It's not really a TL, but a solid ported enclosure that's for sure. Gonna post pics when your done?

It looks harder than it really is.....the key is take your time and measure each piece twice before you cut it.....

Notice most of the pieces are 12.5" wide except for the sides.....when you get the sheet of MDF, have the store cut you 2 strips 12.5" wide off the sheet. You need a total of 115" of wood 12.5" wide, you will find it easier to do the cuts for the individual pieces if you are only wrestling with a narrower strip of wood.

Don't go nuts with the screws, they are there to hold the wood together while the glue dries.....3 or 4 on the shorter lengths will do, 5 or 6 tops along the long edges. Use enough glue to make a mess along the edges when you tighten the screws..... Corner clamps are very handy to have to hold the panels while you are pre-drilling the screw holes.....don't forget to use a counter-sink bit so you can flush in the screw heads, it makes carpeting the box afterwards a lot easier if the screws aren't sticking up.....

Take some pics while you do it and post them here.....if we see something going awry we can let you know right away......and most of all, have fun.....

Do a proper terminal, don't run the wire out the port.

Also would one sheet of MDF be enough for this box, do they come in 4x8 sheets?

One sheet will be plenty. Source always has speaker terminals, as well as most car audio shops, princess auto too, etc.

Make sure to plan your cuts too, so you don't end up with a bunch of little useless pieces rather than a nice bigger piece that you could use later. Or if you miss cut a piece or damaged it during fabrication you can cut a new piece.

Oh and another tip, if you're cutting the MDF inside a garage/workshop (or your parents basement, LOL) make sure you cover stuff up, because the MDF dust is very fine and gets EVERYWHERE. On that note, if you're concerned about your health, a dust mask is an excellent investment.

Nothing better than building speaker boxes, you get to see the working, finished result of your hard work and it's so gratifying when you test it and it rocks your ride.

Good Luck!

Don't use screws I did that on my box and it split the wood, seriously use nails. Glue good idea like they said measure twice cut once measure 5 times cut once trust me lol. Also use a proper terminal radio shack, the source, fs, bb and a local car audio shop will have it.

And yea I screwed mine and yes I pre drilled it still split.

I find that happens if the predrilled hole was too small for the screws....

I have noticed that a screw with threads all the way up the shaft seems to work better than the wood screws that have no thread near the head tho.

I still split one once in a while if I get too close to the end of the board.........sigh

Yup, a good course thread particle board screw or drywall screws work the best. Just make sure they have a good course thread and the hole is predrilled to at least the diameter of the screw shank and at least 1/8" deeper including the counterbore. If you stay a good inch away from the end of the board, you shouldn't have a problem.

I'm just not sure about glue alone, maybe for a ported box, but I would never go that route with a sealed unit.
