I need to put some wood on the inside of the box to take up about 1-1.5 cubic feet inside my box. I think i could take up some volume by bracing the box.

what is the best way to do it so i dont screw up the acustics of the box?

why not just build a new box?

You could make bracing... or just make it a double chambered box. But that would require you to take off one side of the box so you can slide the piece in and screw it in / glue it in.


But, x2 on just building a new one?

as you can see the box is jammed in the back deck and bolted in many places. The box is 4 cubes net which is much too big. I need around 2.75-3 cubes

If i did a brace in the shape of a cross, would that affect airflow at all?

Actually I can't see, but I'll take your word for it.

However, any bracing (as long as it's not in the way of the port) will effect the pressure. Just keep a good distance from the port and you can put whatever you want in there.

Just build a new box. If you built that one right, you'll need a saw to get it apart.

you can use empty coke bottles to take up dead space.....

I dont know what kind of box you build but i screw my back panel in......

if you change internal volume you would have to refiqure ur port length to get the same tunning

LMFAO....i think your mom busted you at the end of the youtube vid. :wow:

-yes you can use coke bottles. its hard as a mutha to compress them. they will rattle and slide around though. you can use anything you want that has volume and wont compress.

Will Castro always seemed like a not so good business man. You can't run around yelling at your employees all day, no wonder he came and went.
Apparently Remi, the shop manager opened up another place. He seemed cool.
It seems that some of the problems with the "big" custom shops is they make unrealistic deadlines (that may just be part of the tv thing to keep it exciting) but it's no wonder they cut corners...other than having NO INTEGRITY as people.

So far I have enjoyed the Street Customs show, that is featuring West Coast Customs.

hey it's an idea. remy was for real pouring sand in to a sub box (if im lieing im dieing and i aint shed a tear) it would take up space but ide imagine it would destroy a sub

if u filled a coke bottle with sand though, and idano like duct taped it on the bottom of your box that could work.

quins90lac

yeah but you would have to know the volume of the bottle to be able to subtract that from the box volume then you would have to recalculate your port length .whats wrong with the box you have built now looks good to me but if you realy want a change im going to have to agree with every one else and say just build a new box . and you really don't need all them screws in it

Sand and resin?

i'd think sand would blow out the port and maybe be destructive to the sub......maybe use bricks...that are wood glued to the floor of the box

set your table saw to a predetermined cut,( the amount you need to remove for req. airspace) run your box thru on all 4 sides, put a new end on and there you go.



or just build a new one:)

williambrea
11-15-2008, 06:46 PM
okay im going to find out the true volume inside the box. Im going to first brace the box with a cross made of 2*4's. Im glad i didnt glue my port flares, just taped! So i can always cut them to match the airspace. If there is any space left over, i will either use bricks, or 3/4 mdf on the botton of the box.

how can you make resin take space in a box? I thought that just soaked into the wood?

phantom240
11-16-2008, 01:24 AM
A certain amount will. You could add packing peanuts for more space and less resin. lol.

williambrea
11-16-2008, 02:25 PM
i think im going to use bricks @ first to just see where it sounds good, then use resin and Mdf ect when i have it where i want it!

i found a bunch of wooden blocks that i can use, somebody recomended using pillow stuffing, or somthing of that sort to fill it up. Not PolyFill Has anybody done this?

11-16-2008, 10:14 PM
Will have the same effect as polyfill.

Styrofoam and glue. Easy to calculate, easy to cut, no extra weight. You can get sheets at Home Depot.

How about some of that expanding foam? It sticks very well and dries pretty hard. Maybe just form a layer on the bottom?
