ok so I was playing around with cutlist tonight and was trying to get the dimensions down right for the coaxial build that Im working on. my problem, Im not an engineer... haha


anyone that might want to assist me with getting the box dimensions correct, please help!!! I want a box with a slanted front baffle to allow a good angle down to the seating position and would love for some help to find the correct panel dimensions so I can plug them into cutlist and get started!!


the dimensions, using 3/4 inch auruco are as follows:


rear and top panels should have a 12x12 inch layout, tapering to an 8 inch bottom panel, and whatever size the front baffle needs to be to accommodate. the side panels will obviously be oddly shaped with the taper from 12 to 8 inches. there will also need to be a slightly longer rear panel than a straight 12x12 to allow for the angle cut necessary to flush it up with the front baffle (which will also need probably an extra 1/4 inch for the same purpose)


If this is too much to ask, ill go trial by error, my mind just doesnt think in these ways and trying to draw it up on paper has been futile so far.


thanks if anyone is willing to lend a hand.


also, considering the 3/4" depth of the ply, the front baffle would probably fit into the interior of the bottom/LR/top panels with the side panels, looking from outside the box, the sides that have no panels tapped on top but rather onto the sides of the panel. if that makes any sense

Why not just draw it to scale on paper?

lilmike, that looks like what he was talking about. once you master sketchup, how long does it take to create a simple picture such as the one that you posted above? just curious.

Master? Sketchup? Me?


Seriously?


I think that took me a bit less than 20 minutes to whip up. I started after reading Roger Dressler's post, and posted the drawing at 10:20.


Believe me, I am no master, not by a long shot, but I do have a LOT of hours invested in learning all about how not to use Sketchup.....

Beast, I'm not a master, but do use sketchup. Got a deal for you...you come over, I'll give you the sketchup drawing you want and you give me some REW lessons and measurements of my room.



We could also do a sketchup of your entire room to help you study that new AT screen you're putting in!

One day I'm going to try and learn sketchup. I started playing with it one day and like most guys didn't read about it first, got to a point I needed help then went and looked at their manual and my god! I can promise that building the entire line of Ford cars that year would have took less paperwork! I gave up right then. Didn't want to put an entire set's worth of encyclopedias in my head just to learn a program. I will some day though.

Sketchup is easy to learn. Just follow the step by step video tutorials and hey presto! your a master. Best free program on the planet. The version I found had a whole bundle off plugins too. Wicked! That drawing should take no longer than 5-10 mins. I can normally design a whole sub in about 30-40 mins normally.

Looking for something like this?




Simple Sketchup attached.

Thanks lilmike! That is exactly what Im looking for. is there anyway that sketchup would be able to derive the front baffle size by giving all the other dimensions? and also the cutout size of each panel?

I was shooting for a half cube anyways so that is great! That was one thing I had calculated was the approximate internal volume.


When I get home I will try and mess around with sketchup some. Id like to make all the other panels all flush up to the side panels so you wont see the layers of ply, since ill probably be doing some magnetic type speaker screen on the front, that would be the best place to have all the panels show. This will also aid in the cutlist rips as the front, back, top and bottom panels will all have the same width
how hard is this to do?


Thanks again lil mike

Here is one to start with.


You can pull dimensions with the tools in Sketchup.


Happy I could help out with this one - I am very interested in your results.

Ill check that as soon as I get home!! Thanks man! I will definitely post the build progress with pics and then response graphs upon completion, I too will really have trouble measuring them outdoor GP unfortunately. I still think we will get a decent reading on them in my room @1m.

I posted it over at techtalk, but some of you may be interested in AutoDesk 123D. It's in beta, but pretty interesting. Feels a lot like Solidworks, Inventor, Pro-E, etc. Probably less user-friendly than SketchUp, but still pretty simple if you ask me (disclaimer: I use Inventor at work haha).

Each panel is a separate component in the drawing. That way you can select any of the panels individually, move it where you want it, and rotate it as you need it.


I used the Select Tool, the Move Tool, and the Rotate Tool to align them the way I did, took just a couple of minutes.


All of the tools are detailed here:
