Face Calked:

I counter sink ~1/8 for all the screws and wood fill the holes after complete, then sand when the entire box is complete.

When I'm finished I post the rest.

I like the disclaimer that you had to work with the specs that he gave you. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Tell him that box it .5 cubes too small and not enough port area. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Nice work though. It should do ok.

First thing I thought. Give her 2.25 daily and she'll sing a beautiful aria.

Nice construction though, looks very nice.

Thanks,

I guess I'll wait until we can test with the sub and sees how it performs.

the forum is for ford mustangs. corral.net/

I have a couple more boxs I built to show just have to download the pics.

 

[PowerNaudio 10+ year member]

i have heard them in small enclosures and they still thump but cabin gain played a big factor on how it sounded. so i hope that you will get the same results.

the build looks good. keep the pics coming.

Heres about the final box, I still need to sand it a bit to clean it up.

 

[dkmesa 10+ year member]

That looks really clean. Good work

I'm sure the guy you made it for is going to enjoy it

Does the tuning frequency take into account speaker displacement?

 

[rpfuror 10+ year member]

yes, the total net volume is 1.78 cu/ft. ~.18 cu/ft for driver displament.
