Worklog : Slot ported box for 12" TC-1000

[Big Dee 10+ year member]

I know a lot of people enjoy build logs so here ya go. So far I've cut everything and painted the port. I also rounded the port edges. It's gonna be around 3-3.4 cu ft NET, I don't remember the exact number, and it's tuned to around 24-25 hz. It has 25 sq in of port area which is more than TC recommends.

The front baffle is double thick and everything else is 3/4" MDF.

Pieces all together, paint cans that I used. Got them from Lowes for 3.12 a piece IIRC.

The speaker cutout was made with a jigsaw. It's about the 4th speaker hole I've made with a jigaw and I'm becoming exceedingly efficient at it (sorry I just watched The Matrix Reloaded //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif) seriously though I am much better now than when I made my first hole.

Close up of one port wall. Used 1/2" bit on my router to make the curve. I also used some wood filler on the edges of the MDF then sanded to make smooth and ready to paint. I also sanded the MDF of course. 320 grit I believe.

I'm gonna glue it now, and I'm gonna use the least amount of screws possible, hopefully none at all, but I only have 2 long and 2 shorter clamps so screws might be required.

This paint and primer from Lowes.

Thanks for the compliments everyone.

Thanks. They were fun to do. I like spray painting. Every piece I did got progressively lazier and lazier //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif, but they all came out good. The first piece I sanded first, then applied about 10 coats of very thin primer, sanded, then 10 coats of flat black very thin with a sanding before the final 2 layers. That took way too long and was not needed. So I did heavier and less layers for the rest, still came out great.

i wonder whats with the small port they say to use with such a big box

I think it's because they didn't want to recommend anything that needed to be bent to make it as simple as possible for everyone to build. The 4 in port that they suggest is only like 12.5 in² though, and I doubt that is optimal. I doubled their port area number so I think I'm good.

what kinda music do you listen to that you want it tuned so low?

 

[PhatTonyDeMarco 5,000+ posts]

God that is a low tuning... Should sound AMAZING. Looks great so far man, keep it up.

 

[ssj2xxgotenxx 10+ year member]

That box is going to turn out great.

Church organs.... I keed I keed //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Mostly rap/R&B.

It's not that I want the low tuning really, I just want flat response, and this sub has a 19 hz fs and needs to be tuned real low for flat response, also I've measured the response of it sealed in my car and to make it flat from 25-60hz this is the box that I will need according to the modeling I've done.

I figured I'd get some comments on the tuning //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif. Lowest tuning ever for a car setup FTW.

What did you measure the response with in your vehicle?

Also, any modeling on a computer is pointless for in-car //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif.

I think it would be an EXCELLENT box for HT duty, actually my Rl-i12 (same sub) is in 3.2cubes @22hz w/ 30 sq. in. of port.

Box looks excellent, tuning any lower than 28hz is just superfluous... you might as well seal it. Personally, I like 30hz or above. Need help getting it flat... get an EQ //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Solid job.
