Hey guys, I am getting my new sub soon, which is a single 15" Beyond Audio Inhuman:yumyum: , and I am making her a pretty home... The box is just over 5 cubes and tuned to 34Hz. I will be using 4" PVC piping for the ports (which is some monster PVC, didnt realize how large it actually is.) I was wondering how I attatch the PVC to the box...?

Well here are some begining pics.:D

Make the hole cut out with a hole saw or router so it fits perfect then attach the ports and from the inside coat the joint with resin.

bro get on aim

otherwise, just dril some 1/2 inch holes to predrill, about half way through, then 1/8inch holes to get it the rest of the way, then just drill through it at an angle through the pipe, into the wood.

another way to do it, is hotglue it, from the front, then flip it over, and resin the back in with fiberglass resin, make sure you 10grit sand the pipe first though, so it'll grip good.

Did you get the shipping quote for me? And also, do you know what the cutout dimension is?

I used Liquide Nails on the inside (gobs and gobs) then took a router and put a rounded angle on it (cutting the PVC as well as some of the MDF). It turned out like an Areoport sorta.

if im using 4" ID PVC pipe. i cut a 4.5" hole with my jasper jig, i put a SLIGHT taper on the hole with my round over bit, wrap electrical tap on the port end and POUND it into the wood. this makes for a very very tight seal. its also very strong. i cant wiggle the port out. it takes some serious pounding out

/\/\/\/\ good idea.

i think they make a collar for this for plumbers actually.

construction adhesive, ca glue, liquid nails, all viable solutions. best way to do it would be to get some ABS plastic, cut a ring with the ID of the OD of the tubing, like a big rectangle with 4 holes in it, trace the holes onto the box and cut them out too, then CA glue the PVC to the ABS plate you made put gobs of liquid nails on the backside of the plate round the PVC and slide it in... then maybe some more on the inside of the box too for shits and giggles,. then just put a few nice screws thru the ABS plate into the box. if you put vynl on the box, then put the port\plate in, it would look pretty sweet (paint the inside of the PVC or get black PVC.

these work too;

just reverse them and the OD of that little flange is what you cut out of the box, the rest of the PVC slides inside it.

Okay, today I got the holes for the ports and sub cut out. I realize I am not the most skilled with a jigsaw, or any saw for that matter, but I think it turned out decent. This is more of an experiement box anyway, to see how I like working with the PVC, so if it ***** then oh well.

Yes, I know you see my toes.

All screwed in... (I used Mike's advice, seemed the easiest.)

I am going out to do a bit more work, hopefully this will be finished tomorrow if I find the time... Otherwise I will have to wrap it up this weekend, I am still comtemplating carpeting it.

And I ordered my amp today as well, Planet Audio 2250D. This time I will be not so generous on the gains..... :p:

looking good bro.

i'll help you carpet it, if you wanna bring it to tally.

for 20 bucks (materials cost pretty much)

it looks good thoguh, should be loud, what tuning are you going for, i dont know if i missed it in the thread?

looks really good, alot better than that last box i saw you were building.


: )

and perfect with those pipes, like i said though, hit it up from the inside with resin if you wanna fork up 12 bucks for a quart of resin, and that way you can resin the insides of the box a little bit at least.

i bashed my head on that very sub so i can vouch for how strong it is and how much pain it can cause

Well this is as far as I got before I had to leave for work, hopefully if it isnt raining tomorrow I can finish her up and maybe do a test run with my buddy's 15" Mmats Procast.

And dont pay attention to that extra ~3 inches on the one board, the Home Depot idiot cut it to the wrong size, so I'll just knock it off with the jigsaw when its all together...

anyways, nice box. looks great

break those screws off that came through the box and caulk over the holes they left.

it'll make it look cleaner
or if you have alot of sawdust, you can mix some wood glue with sawdust and then you'll have some wood filler, you can fill it with that.

It's 27 x 19.5 x 23.5...

So ~5.8 cubes before displacement... This is a too small?

I'm gonna have to side with Eugenics on this one, a few others I have asked have agreed that the box is not too small as well. The pictures just make it seem small...

5.8 cubes, .6 cubes of port displacement, and 1.8 cubes of sub displacement (according to WinISD's specs.) I cant imagine making a much larger enclosure...

Okay I got it all put together tonight, I still have some caulking to do but it is basically finished. I am still not sure if I am going to carpet it, I am unsure if it will fit in my trunk as it is so carpeting will only add thickness...

at least spray that thing with some paint in those ports, unless you want to leave it completly in the ****.

Ummm...it ISN'T 1.8 cubes of sub displacement...NO WHERE near it.

So, your ports are about 21" long? It'll end up being around 5 cubes NET @34hz, ~51 in^2 of port.

I'd flare the edges of the port as much as you can...use a dremel or coarse sandpaper. Also, why'd you get the THICK walled PVC...next time use the thinnest ****.

For a 15"...i'd use 4-4.5 cubes NET @31-33hz...and use aero or precision port flares...

I got that 1.8 from the WinISD specs on the sub, I had no other place to get information on the sub... The ports are 19" long and that was the only 4" PVC piping that Home Depot had.

Okay well the ******* box doesnt fit in my trunk..... It would fit if not for the hook on the bottom of the trunk opening for the latch to lock, i tried to get that ***** off but couldnt get it out. I guess I'll be making something else, unless someone has some ideas for me.

man that really ***** im sorry, maybe asemble it in your trunk? can you post pictures of the latch or something? perhaps we can give you some pointers. i'd hate to see all that hard work not being put to use

My friend has a single 15, so I might just give it to him.

But how would I go about assembling it in the trunk? I dont think I have enough room to work with, it is like the exact height of the trunk as it is, I wouldnt be able to out screws back in the top/bottom which is what I would need to remove. I'll try to get some pics of the latch up tomorrow or something, or I might just go for something simple and make a slot port up tomorrow or Sunday afternoon.

When i built my SS for the neon it didnt fit in the car either, try removing the hook, in the neon they were removable.

get out a sawzall, and cut a small notch in the box on the bottom, once tis in the car, you can put some fiberglass on the inside of that hole and you will be all set :)
