MDF isn't airtight, fact or fiction?

[Bumpin Expo]

I read around and a site said MDF wood isn't completly airtight and that you should run atleast 1 layer of fiberglass resin to plug up all the tiny holes in the wood. So what do you say guys, fact or fiction?

[MDIFYTD]

It's probably true in theory but the cone of your speaker probably leaks more air then MDF ever would.

[93ex]

id be mroe worried about seams and terminals before i was worried about the mdf leaking air.

[TBSpyder]

The amount it would leak isn't going to make rat's chance in hell of a difference. Although I have seen people spray that rubber shit or even dynomat the interior of their boxes as an extra precaution. Not really worth it in my opinion.

[TIM TIM TIM]

i sprayed rubber shit in mine but i didnt use mdf... 10ply plywood lol... its free what can i say

[Bumpin Expo]

tsk tsk tsk

no wonder ur shit sounded like ass

Wow. :nono:

[dropcivic]

Fact. Maybe i take my boxes to seoriusly. Fiberglass resin over the entire interior of the box with two layers of fiberglass mat on all the seams.:D No more air leaks.

[Bumpin Expo]

very nice, I did that once on a box and decided it was over kill and never did it again lol (resin on all the seams with mat)

[TBSpyder]

Major overkill. If you make a box right, you shouldn't have to worry about it.

[aaron1017]

I just put my boxes together with Liquid Nails and some screws and I NEVER have had an air leak at all. If you make your box correct you shouldnt have a problem.

[TIM TIM TIM]

my dad is in construction.. he has some glue shit thats liek stronger then the actual wood.. meaning if u break a piece, glue it back togehter and try to break it again.. it wont break where u glued it 9 times out of 10... but theres nothing rong with the wood.. and sounding like ass? i dont think so it was cleaner then anybody elses that i knew haha..but w.e if yall think that mdf is the almighty wood then go spend the extra money on it :)

Dude, please, save yourself from further criticism. You've been officially banned from AHQ. :roll: :lol:

[TIM TIM TIM]

ok jackass does the rubber spray in there not help seel any little holes there would be?

so was my mdf wood we walkd out of lows with it and put it on top of curtis's truck and left

[TIM TIM TIM]

lol julian ur joints all suck tho so u coulda just used reg wood

they are made right but need some extra in it. When you strive to be the best, you need more strength. I got tried of blowing out om seams after a comp so moved up.

Yeah, but couldn't you have just tongue and grooved the joints and/or doubled up the wood along with interior bracing??:?

[dropcivic]

there was interior bracing inside that is funny part. I almost got to the point of putting some all thread through my box and hold it togther with that. I am trying a new box desgin that involves pvc pipe and shot concerte.:D

[eli]

im gonna use mdf also, its the 2nd best i think besides fiberglass.

Tim you are banned from here. I'm gonna tell Jesse to give you "read only" rights in here because your posts are worthless. haha.

Anyone who is everyone knows to use MDF wood, I mean honestly.

Almighty newbie quote of the year

[TIM TIM TIM]

curtis shut up i have seen the work u do on ur boxes and it looks like shit...so dont run ur mouth...shitty box with good wood. good box with shitty wood with ruber coating inside... hmm which would u rather?

[Kirk]

Not to be rude, but go to any stereo shop and ask them, MDF or plywood.. see what their response is. End of story. ;)

[TIM TIM TIM]

ok u guys win.. im a moran what can i say

[Kirk]

I wouldn't call anyone on here a moron, everyone has to learn somewhere right?

Go here and read up on boxes:
http://www.electronixwarehouse.com/education/enclosures/main.htm

:)

[TIM TIM TIM]

in that site the only bad thing it really says is that its heavy..altho i didnt lead blast it or w.e that is...owell whatever ntot a big deal to me.. i dont build peoples boxes for them for a reason :D

:lol:

:lol: :lol: :lol: :lol: :lol:


and again this is why u should be banned

Id rather take shitty box good wood. Why make a good looking box if it sounds like shit. And yeah boxes in the past looked like shit, what am I supposed to be perfect on the first try? No i did it all by myself, I am self taught, I dont rely on my dad to make shit for me. If u have seen my current setup its pretty clean so I wouldnt run my mouth if I were u, u already look dumb enough:lol: :lol: :lol: :lol: :lol:

[TIM TIM TIM]

curtis.. as u said n the other thread.. "unless u use 3 layers... try 4 coats of spray then painted the liquid rubber stuff inside..it was actually really nice plywood by the way...it was more dence then what yall are prolly imagining but owell i c where ur comming from... but curtis sorry for having a dad that helps me out, and he didnt do it all for me

[Kirk]

you guys arguing over who looks cleaner, well.. atleast i got a trunk! and what :p :p :D

[Bumpin Expo]

lol

Hey kirk i kno this is off topic but what ever happened to ur car with the gun thing

[TIM TIM TIM]

i have a trunk... i just cant use it lol... na i got a lil room for like towels or blankets.. dont wanna scratch the plexi glas tho lol

[Bumpin Expo]

from the pics in ur sig, it really doesnt look like u have a trunk nemore :lol:

[TIM TIM TIM]

correct me if im wrong.. but the part n the front where the engine sits would be the hood... right? trunk is n teh back :D backs fine... :lol:

[TBSpyder]

Plywood isn't only at a disadvantage because of it's lower density....the fact that it flexes so easily under pressure is also a major flaw. MDF is far superior to playwood anyday of the week, it's the industry standard for box fabrication. Like I said, anyone who knows anything about car audio knows this. Learn from your mistakes....just don't tell anyone because they'll laugh at you.:lol: ;)

[TIM TIM TIM]

laugh if u want i really dont care.. if my wood is flexing i would be amazed.. if u wanna get technical the plywood my box is made out of is stronger them mdf bored if u wanna compare in teh way.. ok mdf is more dence.. i understnad its better for the system but mine works just fine for me so get off my back about it

[93ex]

mine is made of hopes and dreams so fuck yall

Yes, i have made a box out of mdf. Worse box i have ever made(for me cheap brother:lol: ). The box flexed and cracked. It sounded like ass, and when the road flexed, you could hear big time distorion. Unless you are using something like 1 and half think pylwood, the box is shit.

ok ur right my boxes flex like crazy and seep out tons of air.. fucking retard ur mdf is flexing more then the plywood jackass, its not ur every day plywood that you prolly made your box out of... 10ply 3/4 inch..your averadge would be 4-5 ply...big diff there so shut up and go try to make ur honda fast

[TBSpyder]

:nono:

[TIM TIM TIM]

isnt mdf like a particle bored?

[TBSpyder]

Originally posted by whtmustangt99

No. Particle board is even worse than plywood...so atleast you did well in that sense. MDF is more of a composite, condensed under extreme pressure to create it's higher density. Hence it's weight.

[TIM TIM TIM]

so its pretty much a very dence particle bored..basically..right?

and im not a complete jackass with it, yes plywood may not be the best choice but i also dont think it was the worst... who cares tho, its my system, im satisfied with it, all my friends seem to like it...and the way it looks :D so thats all that matters

Fibreboard. Bonded under pressure by heat and resin glue. You're right, it probably wasn't the worst choice....I've actually seen boxes made out of cardboard before.

okay dumb ass. I am sponsered by image dynamics and have the loudest dbdrag street b car in the state of FL and 8th in the nation. You think you really want to try talk setups to me? I have learned more about 1/4 theory, standing waves, and physics then most people can even begin to think about. Why don't you go look at some of the loudest setups in the world and see what they are running, plywood or mdf. Here is one that i helped on.
http://www.termpro.com/asp/competitorstats.asp?Competitor_ID=10041&Season=2002

do want to know what the wall was made out of? Three layers of 1" mdf. By the way, i drive a 4runner, not a honda, but i am building up my crx. Don't be mad that you drive a ford.

[TIM TIM TIM]

why would i be mad that i drive a ford...spend hours and thousands to make urs the same speed lol... but ok i understand mdf is better wood, its more dence and stuff..but mdf is basically a very dence particle board, so i am told... and im not pushing a bijillion watts threw it iether.. i got 1000rms at 2 ohms. but im runin at 2.6 ohms to 3 subs.. so i guess 850 or so watts divided by 3... i doubt the plywood is flexing..

You'd be surprised actually. To the untrained eye (or ear for that matter) it may seem like no difference...but in actuality, switching to a properly built mdf box could result in quite an increase in both sq and spl. You might want to consider giving it a try...a $20 sheet of mdf, an afternoon, and a few beers could greatly improve your system.

[93ex]

yeah whats the worst that wouldhappen, it sounds worse? back into the other box..

[TIM TIM TIM]

no, its not a regular box.. its all odd shaped and stuff to fit in into the trunk.. each box would take a good couple hours to make... not worth it to me..

edit: now i no for next time.. ill use mdf...

[stangerang]

i make my boxes out of u haul cardboard boxes, they always sound great!

i think ill just quit posting in year yall are a bunch of bashing queers with nothing better to do with ur life then investigate car audio and critisize everyone that doesnt live up to your standards

I don't critize. I like to help but you came in here and started it with me. Yes, i have no life because i COMPETE. Audio is what i know and what i love. Grow up and get over it
