Default My NEWLY ported box project

I made a ported box over the summer and I was really unhappy with it, it was big, bulky, looked bad, and slid around a lot.

So I decided I'm going to build a new one and put it on the back side of the trunk. I'm debating on a slot port or 2 circular flared ports, if I can get them to work lol.

So today I made a mock set up in cardboard, trimmed, and put it together to make sure it went in and out with no problems, and it works well comes in and out nicely lol

So I'll be running my Directed Audio 2400D amp with my RE SX12 (Resonant Engineering, www.reaudio.com) tuned to 35 Hz with 2.0 cu ft after sub displacement

here's the mock setup, hopefully it will turn out just how I want it, the majority of it will be made out of wood, with the corners and walls made of fiberglass, and i will probably add a few thin layers of bondo for curves and smoothness

I'm wanting to have this done by Sunday evening so if all goes well it'll be done for Christmas yay

i'm running into port fitment issues, my debate now is to use the 2 4" flares and combine them into one which I will construct for inside the box but keeping the same cross-sectional area, or just doing a slotted port... decisions decisions....

Alright, I've been very busy, and I finally had a chance to work on MY box I have a few pics I took from last night, it's not much, but it's shaping together and some better pics will be posted later today!

so here are a few...

This is the back and bottom...




And here is the back, bottom, front and two 2.5" supports to hold the front to the back, for extra air space (have to have 2 cu ft of inside volume, which means a total of 2.42 total outside volume, taking into consideration wood thickness, sub displacement, port displacement)




I'll be adding more pics later today, hopefully i'll get the sides done, and the port nearly completed, or better yet, hopefully all but the final fiberglassing done!

Thanks Daishi

Got it pieced together finally, got the inside siliconed well and now I just need the sides and the part for my pass through which I'm going to be fiberglassing, so while the silicone is drying I'm going to get lunch

then I am going to bust out the Plunge Router and get my port hole ready and cut out my sub and amp pieces so they can be raised up

Port Info Compliments of WinISD

whew, it's been a long day lol
So I cut the circle out for my flare to go into (still need to get the adapter for the flare to the PVC) and I got the circle for my sub to go through, routers are the best thing to have!

so here are some updated pics

Checking again to make sure it fits!






And it does, phew



Drew my guides to make sure I'm going to be cutting on the right place



Holes are cut with my flared port inserted and it fits well, and my mount and trim ring sitting next to the sub hole

Thank you, Well I stretched the cloth over the front and got some resin slopped on it so this will be all for tonight, hopefully I can finish the other 2 boxes I'm working on (for someone else) tomorrow and finish glassing mine at the same time!

then it'll be paint time for me!

not bad rookie. You might want to try and use a drill that's younger than you are. I'm really interested in how the pass thru comes out. I may be doing something very similar to this with mine. Once you've got it trimmed down, get that thing back in the car a get a pic!

LOL /\ /\ my older brother

yea the drill I'm using is my father's... that he won at bingo probably over 20 years ago, but it still works perfectly lol

I'm going to be trimming the corner around the pass through part so it's not a 90 degree angle so hopefully it will look smooth and come out nice

by the looks of it.. its a good design. but looks like the sub isnt going to have much control due to the jsut reg. port hole. like its jsut a box with a hole. its always good to have port length.

What you see on the box is just the flare that a PVC port will attach to. If you look at the WinISD plot he posted above you can see that the port will be 10.62" long.

a. it's a four inch port.... large diameter ports generally have little noise associated with them.

b. it's in the trunk, if it was venting into the vehicle directly might be an issue.

I doubt port noise will be an issue.

lol wow a little debate

In the WinISD if the number is RED then the program says there will be port noise, I was trying out various rectangular ports and decided to try the circular one, and got a length and diameter that fit well

The number for "vent mach." is 0.16 and it is green meaning (according to the program) there will be no port noise, the flare is also going to help with reducing port noise

lol thanks for clarifying that, if someone jsut looks at the pics they think i'm just doing a hole lol, i'm not that dumb lol I have the pvc with the attachment for it to fit the flare and the exit to the pvc

should be done tomorrow!

I'm just going to paint the whole thing flat black because I'm gonig back to school this weekend and won't have time to make it look BA so that will be spring break project or a summer project to get it looking better, but the sub and amp will be the main focus so it shouldn't look horrible lol

I'm currently making two side pocket boxes for someone else so those are my first priority now and then while they are drying I go and work on mine

thanks for the comments
