How come you want it tuned to 26hz? And if your heart is set on 4inch ports, your going to need like 7 of them ??. Are you just not sure you can handle building a slot port or just dont want one?

You can get some i think its 2inch dowl at home depot. would work good. i personally dont care for any internal bracing , but the dowls are round and most likely wont mess with airflow much. just be sure to predrill and glue them up good. I dont think resin or any other coating would help in your case to much if its flexing enough to bounce the enclosure. do you have enough room ro maybe do a layer of 1/2 inch to the outside?

I cant believe you guys pissed on this dudes test???? Im not going to argue anymore, because just as you guys have told me how hard headed i am in listening , you are no better. You guys chopped up his test like crazy. Like i said before, NONE of use are going to push the MDF to the point of finding its newly found brittleness that the resin adds. BUT, we will be able to use the small amount of hardness it offers buy stopping a few MM of flex. And thats just an added plus to the smoothness the TL loves from the stuff.

this is what ive been tryin to say. the brittleness the resin will give the mdf dont out wiegh the slight hardness it gives. our enlcosures wont push a piece of mdf the point where it matters that at XX amount of inches of flex it snaps sooner than no resin...

How am i handling myself any different? Im asking a question to support his statements and getting more smart azz replies. Im really sorry you dont enjoy the way i handle myself . back to the point... A- does the resin make it "harder" it only makes sence that it does, or else why would it be more "brittle" its yes or no.. B- is the 2 or so mm the enclosures going to push the mdf going to push to this failing point?? yes or no .. as for dem beats i will also as you for these tests or reports? i really think you guys are thinking into the word "stronger" a little to much. no one here thinks the mdf soaks it up and its like steel. or that a single layer with resin compares to 4 layers.. But a nice heavy coat inside and out will help eliminate some flex

Then test it. Really easy to do. I am very much wanting to know why you think the opposite. why dont you answer me 1st?

Of all the boxes I've seen glassed ( and I've seen a few ) I've never seen one crack or break because of resin and I'm not talking about 1200 watt systems. LOL And then they wouldn't have cracked or broke without the resin either. I never said that when you resin MDF that the box will break automatically, just that resin does not add strength but reduces it. that's i guess the question i'm getting at. aren't there better ways to increase the rigidity of mdf, or stiffer materials that can be used in place of mdf? sure.. but i dont see anyone wanting to invest the time into steel and concrete for daily drivers. the closest thing we have tested thatt showed gains was birch around .7 box for box swap. but im not sure people like maybe 43 a sheet for that and im sure M5 will tell us how much burch sucks as well..

like i said.. then you can show us your reports from your material tester?? and you have yet to explain why it reduces it? answer me this. if the mdf become brittle. it means it became harder, but more easy to break in a stressfull situation. correct? i will aggree.. now do you honestly think that in car audio we will bend the mdf enough to fail because of this brittleness? i dont think so.. ever... so the initial hardness that the resin gives the mdf. makes it HARDER...

From Wikipedia, the free encyclopedia Jump to: navigation, search "Brittle" redirects here. For other uses, see Brittle (disambiguation). Brittle fracture in glass.A material is brittle if it is liable to fracture when subjected to stress. That is, it has little tendency to deform (or strain) before fracture. This fracture absorbs relatively little energy, even in materials of high strength, and usually makes a snapping sound. When used in materials science, it is generally applied to materials that fail in tension rather than shear, or when there is little or no evidence of plastic deformation before failure. When a material has reached the limit of its strength, it usually has the option of either deformation or fracture. A naturally malleable metal can be made stronger by impeding the mechanisms of plastic deformation (reducing grain size, dispersion strengthening, work hardening, etc.), but if this is taken to an extreme, fracture becomes the more likely outcome, and the material can become brittle. Improving material toughness is therefore a balancing who give a shit if its more brittle? its HARDER thats why its "brittle". to push a piece of MDF to the point of its new found "brittleness" breaking Would be far beyond anything this guys or anyone elses system will do..

Sorry Jordan... according to "M5" i have made your enclosure a brittle shit box by resining the inside....

And strength is NOT the reason it is used very often. no.. its just not the ONLY reason. i dont get why your such a dick . i havent seen one of your post where you tried to help anyone with out being a dick head about it . and with no logical reason for why you think what you do. its very pucking much this simple. im not a noobie man, ive been around and tested plenty. period!

So you have had mdf just crack apart from being brittle? If you take a carboard box and soak it in resin would it be stronger? i guess terry is a complete idiot and its brittle enclosure is going to blast apart >> http://audioforum.termpro.com/topic/8/27273.html WTF, that has nothing to do with anything. I didn't say it would make it super weak, just not stronger. I see you avoid my question over why you think it is stronger though but are quick to judge otherwise. If you put mdf on a material tester and test its breaking strength both with and without resin, the piece with resin will break with less force. you said it makes it brittle. In my 29yrs ive learned that something brittle is weak and cracks easy. maybe im wrong about that as well. i think its stronger because it dries hard as hell. its very simple. and wtf ever a "material tester" is ,im guessing you have one of these? and can show use your tests? i will ONLY agree that resin alone is not a strong as resin with fibers or glass mating. but mdf soaks the stuff up and its harder when its done. this is nearly as good as your argument that walls arent loud..

i have tested it . its used very often in spl applications. But im just a noobie to the car audio world

How does it take away strength?

Im very much wanting to know how resin makes a enclosure weak

ive got the front all wrapped and finished up now for the most part. hopefully can get some pics tonight.. once he decides and and get new amps i will finish and post some pics of the back up

just the 1st layer.. fitting the trim.

start or the baffle.. missed laying out the port pics the ports funny looking because of the way i had to mount it. building the boxi n the truck double layer didnt leave me with many options to mount the port

got the back on.. hope it likes 45s lol all greased up with few resin coats

This thread is making me sleepy..... maybe i should make one for jordans trailblazer..... and whos this homo alan you keep talking about? is he really going to help you with this crap or what?

Yeah im tryin to figure out how that woofer is going to fit. i had a hell of a time stuffing this 1508s in a f250 http://viewmorepics.myspace.com/index.cfm?...albumId=2868795

Im just wondering. In my next van build, i should just order some boss or wolfenhags or somthing to test with?

i just did an install with 2 of these and tested them around 1800w.. as for all hofonics being junk. the xx line stomps ass as good any anything out there.

What you got?
