I will have two 10" infinity 1052w woofers. The following is the spec sheet that came from infinity's website. I think I would like to make a ported box because I can make a smaller box and get a lot of bass.

On the second sheet, it shows a sample box design. For two woofers, would I just double that design? Should there be two ports or one? Are there any rules to volume when you have two woofers in the same box? I Know very little about box design and have never designed a box.

Make a box with around 3-3.5ft^3 net volume and tune it to around 30Hz unless you wanna go lower. That picture you showed said 28Hz.
If you need some help with it, just PM me. I can help you out.

ok, so this box is 1x3x1 so it is 3 cu ft. volume. I am not sure how to make the port so that it is tuned for 28-30hz. Right now I just made a slot that is 9 inches long into the box and then 3 inches hooking inwards just as a mockup but I am not sure how to calculate how this slot should be.

I modeled this sample enclosure plan (from the sticky) in sketchup, does that look about right? Is 3 cu ft what I need?

Ok its about 80% complete, so far so good. Ill post pictures when its complete.

Its going to have mismatched 10" woofers :crazy: till I get some more cash

this box cost me about $70 in materials so far but the thing is tough, I could probably put about 500 lbs on top.

Any tips on upholstering? I am wondering which area to start upholstering first and also where to hide the fold.

Some people carpet their boxes that way^^^
Others have another method, but you have to cut your sides differently and I am sure you didnt.
both ways work fine.

Okay, thanks. Im also wondering about the cheapest place to get inset handles, I might just have to cut my own out of mdf b/c I don't want to pay $30 just to add a few handles.

You plan on taking your Box out a lot? >_>

If not... do you like being easily jacked?

I drive a 99-00 model civic si with the blue paint so its only a matter of time anyway.

Gluing went well, the carpet looks pretty nice, Im gonna remove a couple of the staples after the glue is nice and set tomorrow. Since the box is fairly large I did the ends and then wrapped it longwise with a big piece.
