15" Fi Q Box - Worklog w/ *Pics*

[kicker06 10+ year member]

Here is a box out of 7ply 3/4" Birch plywood I started building today. The specs are 4cu @ 32hz w/ 69" of port.

I used 4 braces to keep the walls from flexing. The ext dims are 30x30x14

The last thing I did tonight was spray the port with primer. Later tonight I will spray it with paint and tomorrow the top goes on.

Looking good.

Just curious would it make the box stronger by placing the brace perpendicular to the box, or would this be better to reduce flexing?

No problem.

15 inches ported in a trunk car. Very nice. i'm trying to convince my friend to throw a 15 in his accord. I don't think it'll happen tho. Are yuo going to carpet this box?

It makes the walls not flex, it is a brace that has worked for many people.

Yes, I will carpet it eventually.

BTW, just painted the port. Top goes on tonight as well as the cutout and silicone.

Tomorrow it will be hooked up.

Got that design figured out huh?

How did you brace the top/bottom panels since those are the biggest and most likely to flex?

Personally I would have done your side braces like a "T" so it ties into more of the top/bottom panels.
