Well today Im going to pick up some things from Lowes to start my build for my 2 12" HDC3's tomorrow. Also to pick out a new circular saw my girl is getting me for Birthday;). So Im more or less looking for pointers or any techniques people use into making these boxes. They seem straight forward, only thing that bothers me is how do you cut the wood, or even cut it with, that goes into the corner of the box that helps with the air flow. I know its suppose to be at 45 degrees, but is there a special tool you use to achieve that? Also does anyone have any recommendations on glue, circular saw, jigsaws, etc. they use and like.

a table saw can cut at 45 but so can a circular saw.

so I can get a circular saw that angles the blade?

make sure you make a nice straight cut guide for your circ saw. I cut a 2 inch strip off of the edge of my MDF that I used to clamp to the wood for a guide. Turns out it was flexing in the middle when I was making cuts and my cuts didnt turn out straight. The box went together OK but I had to use clamps to pull some of the pieces in place for screws

I'm pretty sure at least 90% of circ saws can angle the blade, I've never seen one that can't.

Just get a circular saw at Wal-Mart, that's what I've been using for years now. Just be sure to pick up a nice DeWault blade.

No need to use a straight edge, just focus on the line drawn and ALWAYS account for blade width when making your measurements/cuts.

what he said! hey check CL you can find great deals on there! unless you want a new one haha.


also practice cutting a little bit before you jump right into cutting for your box! next thing you know you have got a box looking all curvy nd ****!

You can use that same method except angle the blade on your saw for your 45* cuts. Then cut the pieces to length.

liquid nails for glue. most circular saw and jig saws come with rip gids to help with straight cuts. i would also recommend corner clamps a least 2

Nah, you need a guide... and a good design.
As for the 45* angles, most people don't do it properly... and it ends up being more of a detriment than a help. You're SUPPOSED to make it so that the port is the same width through out the whole port. (That's the point of them, and to ease the moving air for the turn) You have to cut the other side of the port to make sure the port is the same size through out the whole box. It takes a lot of work, actually... a lot of miniscule cuts to get it perfect... which most people don't do... and it ends up bottle necking the air.

But the 45* angles will be tough with a table saw. Unless you make them wide, then it won't be too bad... but you'll have to take more off the other side of the port.

I actually learned it from you. :laugh:
I saw one of your threads and I was like, "Wow, that's really dope." Then I realized that if you don't do that, the port width isn't the same through out, so it ends up compressing at the elbow.

02-18-2009, 01:19 PM
your first box most likely won't be that great and will need lots of caulk(unless you have an awesome table saw with huge extensions on it) The more you build the better they get.

Haha, that's some funny ****.

Not only does it affect flow (even if it is just minor) but the port area changes, thus changing the tuning.

When measuring port area for square ports, width is obviously a factor. When calculating, you're assuming the width is the same the whole way through the port, giving you an accurate port area, and your desired tuning frequency. If the width is changed at all, it changes the area.

This may not be super important all the time, but for the amount of times that i've seen it neglected, it worries me.

Tehgregzor
02-18-2009, 02:07 PM
good advice, wasted ink. I had never really thought about the width before. I think i'll stick to other people making boxes for me, while i fix their computer :)

02-18-2009, 02:13 PM
ok heres another question, how does making the port longer or shorted or wider and narrower effect tuning, In particular I have a kicker box with a 7" wide (inside) areoport thats about a 1-1.5 ft long. any guestamates on the tuning???

Instead of stickying this, we could start a different thread with a more organzied list of things, maybe different steps and precautions. I've seen too many "My first box build" threads where big mistakes were made because of simple negligence. It could be a list of important things to remember when building, or something similar. Just an idea.

Longer and smaller the port area = lower tuning

Shorter and larger the port area is = higher tuning

And if you have all the specs on that box I could tell you in a second what the tuning is..

Another tip, be patient, if it takes you all day to build the box dont worry about it.
Double check all your math and calculations. Last thing you wanna do is spend all day cutting to figure out you did some incorrect math.

Also making a cut sheet helps utilize your wood to its best ability. Some programs will do it for you, but you can easily do it yourself.

And remember to account for the blade, typically most blades are 1/8" thick so just remember you will lose that on every cut. I know this has got me once or twice

my first box was ugly as hell and all outta line on one corner, luckly it was just the bottom baffel just a lil to long on one corner.

But it wanged to all hell, 2.5 cubes at 28hz hits reallllllly low in a 96 grand prix

And if you have all the specs on that box I could tell you in a second what the tuning is..

box is W- 32", H - 16", front of box is slanted. Top is 14" deep and bottom is 17" deep front to back, the front baffle is recessed about a 1/4 inch and the port is 7" wide and inbetween 12-18" deep

Truf, my first box was a rush job just cause I was anxious to get it in, my second box was the best one I've made yet, sadly it didnt fit through the trunk openings so I had to sell it:crying: it was so smooth all over and sounded lovely

Something like that. I bought them at Lowe's. You get two of those aluminum guides and a connecting piece for like $17. There located in the tool section along with other guides, straight edges, and table saw attachments.

Now just get a few router tables and a couple more routers...one having a roundover bit always on it, the other has a 45 degree bit that's always on it (or for those who are picky...a 45 degree chamfer bit :) )...just zip the pieces you need 45'ed through the one and rounded pieces through the other...dont even have to mess with tilting the blade on the tables saw/circular and dont have to even get a router and roundover the pieces...just turn um on and zip um through :)...that's what im hoping to have setup in the future for teh uber speedz n sexyness'z.. :naughty:
