Here is the box build for my fi q. Sorry I didn't take any pics while building, as I left my camera at home while building at a friends house. I haven't loaded the sub yet since it is sitting under the Christmas tree taunting me.

Specs on box:
2.5 cubes net
Tuned to 30hz
36 sqin of port

Dry fit of pieces. The inside corner wall of the port was also rounded, but I did not have it done at the time of the pic. There is also a 45 degree corner piece on the outside corner of the port.

This is what the box looked like just after construction. UGLY.

Home depot cut my wood so this piece ended up being about 1/8" too long. Not to worry as it was cut off later as you will see.

Thank you.

I'd like to add that all the sanding was done by hand. I would have been able to get a better look if I had an electric sander. I'm also without a router, so I can definitely see how it could look better.

Nice Box, did you say 2.5 cu/ft becuase that thing looks HUGH???

That looks great. Should be louder than poop. Oh leave the cat in there, I think large ones can account for gains up to 2dB!

Yup 2.5 cubes. The pics might be deceiving on the size. Outer dimensions are 13.5" tall, 23" wide, and 26" deep.

We have about 10 cats running around our acreage, should I throw a couple more in for good measure? And how loud is poop exactly?

I really would not like to go back to home depot, but a table saw is not in my budget, nor could I find a place for it.

I had to purposely build the box with an overhang on one panel so the port would turn out correctly. This overhang can't just be cut off like that 1/8" of excess end pictured in my first post. I wasn't planning on carpeting this box, but if I don't find a way to fix the overhang, I will want to.

Anyone got some harsh cristism about this box? I need to hear it if there is any.

There's nothing wrong with that box. If you made it any better, it would just be overbuilt....it looks fine to me for daily purposes.

Many people like to overbuild their boxes though, and there is nothing wrong with that :)

edit: a thicker front baffle may be appropriate, but if it's solid then it wouldn't matter much.

matt_martin87
12-15-2006, 02:11 PM
Not a big deal if I do need to double baffle the front of the box. I was actually thinking the 1" dowel was almost overkill. I've never used this kind of bracing before so I just went big right away. Not to mention it was cheap.

how is the dowel overkill? i bet its still going to flex

Everything that needs to be changed has already been said by you. Ya just need a saw.

Nice work. :cool:

Which panels do you believe would flex the most? I will do some 90* braces if there is a need for them.

Run a dowel from top to bottom as well if you can.

matt_martin87
12-18-2006, 04:28 PM
I just so happen to have extra length sitting around on that dowel. How am I supposed to get it in there exactly? If I make it 12" tall, wouldn't it be impossible to tilt it into position?

Yeah, cats are a form of polyfil that is affective with ported enclosures. Poop is loud enough to make you poop yourself, so have fun scrubbing those seats down...:laugh:

What I do is drill a small hole where I want the dowel to be and then put a flashlight on top of the hole. Turn out the lights and put a mark where the light shines. Then drill a small hole at the mark.

Next make the dowel a hair shorter and tilt in. Tap with a hammer until both holes are covered (the dowel is blocking the small hole). When you get it where you want it, draw a circle where the dowels go. (trace around them) Next, remove the dowel and put glue on it. Slide it back where you traced out. The extra step prevents you smearing glue all over the inside of your box or the top/bottom of the dowel has dried glue.

After everything is set, you can screw the dowel in from the top. Or you can drill a bigger hole and use a small wooden dowel + glue. The wooden dowel method is stronger IMO but more work

I had never thought of using a flashlight for positioning the dowel along the bottom of the box. Nice explaination. The main thing I was worried about was tilting the dowel into place, but it seems like cutting off a hair would do the trick.

nice box... i seriously doubt you'll have any panel flex... a box that small is not going to flex with a fi q... i have two sx 12s in a 6 cube (before disp.) box with no bracing or double baffle and it's rock solid...

Not bad man , not bad at all . Wipe off your excess glue with a damp rag while it's still wet . You will save yourself and arse ton of sanding :)

That works and if you are quick with the tape, you can use masking tape at the edges when you join the pieces that are being glued.

Silicone.


RIGHT. . . . . . . . . . . . . . . . .

Anyways, that is a nice box after the finishing. I noticed that you said you didn't have a router. How did you do the roundovers then?

I used a sanding block. (I don't know if that's the right word for it). It was hell.

Update: The sub is in and working perfectly. I instantly fell in love with the low end in my car. The box wanted to move around by itself before I secured it to the floor, so I will definitely do some more bracing and a double baffle. I also plan on laquering (sp?) the entire box black. Here is a video I threw together for your enjoyment.
