1/2" vs 3/4" MDF question

[Ian Macfadgen]

ok, so... with my great luck, i accidently picked up(and got it cut and everything) 1/2 inch MDF. is that going to greatly affect the inner dimensions or ability to put it together? because i already got a plan drawn out and it was planned out with 3/4 MDF. i didn't realize until i started drawing everything out for the cutouts.

the dimensions are:

front/back: 24x15.5

top/bottom: 24x14

sides: 14x14

and the port dimensions:

p1: 12x14

p2: 9.5x14

should be 2 cubes at 35hz tuning

its for a single SA-12 running at about 800 watts RMS power.

according to torres calculator, i could maybe extend the port width from 2 inches to 2.125 and it will somewhat fix the tuning. any thoughts before i actually go and make it? or am i over thinking this?

[Torres]

it *could* be ok with the power you're running if you brace it properly enough, but structural-wise i'd be more worried about it. if you got it cut and everything, i say you might as well put it together and see how it goes.

i dont know how id feel about 1/2 but im sure you have enough to double layer it and have a stout ass box.

[SnowDrifter]

If the box isn't together yet, cut your losses and go get some 3/4

[HunterJohnson]

For one sa-12 I believe that 1/2 inch isn't sufficient unless fiberglassed. They push alot of air and weigh a decent amount

I'd honestly just buy a sheet of 3/4. Save the 1/2" for speaker rings or something, you'll find a use for it some day.

Unless, like n8 said, you have enough to double up.

i did the same thing but i went a head and made it. i put double baffle on it and braced it. i hope it works out alright

[Ian Macfadgen]

well, maybe i didnt totally lose here. i have a pair of 8" jbl gt82's. im sure i could fit one in here, although it wont handle nearly enough power as id like. or not...

so im just going to brace the shit out of this box and dump a whole bottle of glue in each crack and crevice and maybe some caulking and see how it goes lol. and/or, i could put some 'end caps' on each of the sides where it should be the least structurally sound. it would make the most sense in that case because the cap would be hitting every single piece of the box.

[n8ball2013]

no end caps wont help at all. double baffle the whole thing or resin and mat the whole thing. glue doesnt give you strength.
