Ok, how many should I use? and what diameter rod, I can see this being a very, very good bracing method...

 

I would use 1/2-3/4 threaded rod, and just do it where ever you want. ( i usually do in the middle of each MDF board.... So a total of 3 threaded rods.)

 

You mean like one length, one width, and one height wise? I already got the oak brace for vertical, I might just use the ones for length and width, also, how the hell do you drill those in...

 

Well do one for length and width. I install them by drilling a hole the size of the rod through the box, slide the rod through, and to seal it for leak i use silicone and washers, and to tighten the brace use a bolt at the ends.


To seal it i use silicone then a washer over the silicone which creates a tight seal.(on both sides... ie outside and inside of the box)

Hope this helps

 

Awesome, I understand now, I thought you just mashed the rod in, and I was like "what the **** is the point in that", but the nuts make sense lol.

 

You need a lot more braces in there... Double baffle would be good too.

LMAO

No Problem bud. Glad to help out a fellow CCA member

 

I would also run triangular shaped pieces of 3/4" plywood as braces, one in each space between a pair of drivers to help brace the front baffle to the sides.
Also, do something that'll brace the bottom to the sides as well.

3/4" MDF with no bracing is horribly insufficient for that size of a box.

I didnt have massively huge panels in my 2x MJ18 box, but that thing noticeably vibrated when cranked, and I had a solid 7/8" particle board divider between the two sides.

 

Here is wonderful link on how to sufficiently brace your box.

 

i wasnt being sarcastic. u will have alot of **** noise/wind.
