Making sealed box for IDQ V2 D2, need some help :)

[d4rin]

Ok, this woofer needs 1 cu.ft of air space. I went and measured inside the trunk to see what I could fit. Here are my parameters.

16" W x 13" H x 12" D= Total external volume of box

Total internal volume of these measurements is 1.03 cu. ft inside the box.

Mounting diameter = 11", is this exactly where I should cut the circle in the center of the box?

Mounting depth = 5.75, so the magnet should clear about 4.7" in the internal volume. Speaker should fit with no problems.

3/4" MDF.

Is all of this correct? I wanna make sure the woofer has a proper enclosure for best performance!

Sounds fine... after subtracting speaker displacement you'll be right around .95 ft^3. Within rec. specs.

You should be fine,after displacement you're looking at .96cft. of space.If you wanna be anal you can experiment with some polyfill to get it to 1cft.As for the cutout,yes make it 11'' as recommended by ID.

Yeah, I think .96 I wouldn't hear a sound difference?

Actually I figured out how to get closer to 1.0 cu. ft.

15"W x 15" H x 11.5D = Inter Volume 1.05469 cu. ft.

1.05469 -.07 speaker displacement = 0.98 cu. ft.

Sound better? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I doubt you will hear the difference between .96 and .98, but since you're making your own box, might as well get it as accurate as you can.

What's a good size bit for pre-drilling the holes for the woofer screws?

#6 bit w/countersink

Use the clutch on your drill, and don't over tighten, or you may as well not have predrilled your holes.
