My First Glass Box

I prefer John Deere Green..beins how i have a 39' "B" and a 110...but hey, its your truck!!

I have found over the years that a box constructed of glass and resin only needs about 4-5 layers if its on the small side, like yours. You definatly overbuilt the thing!!!!!! whih is not a bad thing since cabinet resonance is ouR enemy of SQ.......


More dampnig material!!!!!! stuff the shyte out of it and put in an aperiodic membrane!!!

 

Damn Ranger that is a fuking crazy thick box...I was gonna make one but its like 40 degrees where I live now. I was only gonna fleece it and then put like 4 or 5 layers of glass but damn 3/4 inch thick minimum is crazy man

 

If its cold, (or hot out) still use way too much catalyst!!!! it will set......JUST DONT BREATHE HE FUMES!!!!!!!!!!!!!! thats no joke.......dont breathe them..

I like it when the plastic cups melt down from the heat of the resin, and almost ignite.......always agood time..........

 

I bet you could drive over that box and it won't even budge

 

I really wanna start learning how to glass...but its like 35-40 degrees here in southern IN...not really glassing temps lol

 

i could not have said it better.

Nice box. overkill from hell and i love it. if its not smoking when you sit the cup down . your not glassing.

i actually had to use colored mek because i could not remember if i had added or not no bs look

 

Never ever seen any colored catalyst. interesting!

i have been checking out your enclosures, not to bad looking really. I woulod rate them right along the lines of good quality box, And FAR superior to the crap that is made overseas...

Just a question for ya though tech, why do you feel it is required to add glass matte to the box?

LOL! i already have my own opinon on this, just wanted to know your thoughts.

 

well seeing that you asked . i already know your opinion.

well in a perfect world. i would make flawless cuts everytime. and my glue would set perfect due to the 24 hour drytime i allow before ups gets it and doesnt kick it all the way to california. in that case i would not titebond seal or fiberglass matt or resin. because the glue would seal up the box perfect and it would never rattle or come apart.

but we do not live in a perfect world. And we all know prefab boxes are cut with a cnc . cant get anymore perfect cuts than that and they are glued and some use silicone also.and we have all had one come apart and ratlle like hell.

to put it plainly. my father is a cabinet builder as a hobby.for the last 25 years he has been building custom cabinets and furniture.he is very serious about it. And me and him have had this arguement 1000 times. untill about 2 months ago when i finally said the hell with it. had him build me a box with his mdf perfect cuts and glue and screws for one of my solo xs. . let it sit for 24 hours . it played for one day fine. the next day it was leaking in 3 spots.

My answer is glue and perfect cuts are great for moms china. but customers are going use their enclosures and abuse the hell out of them.some of my boxes are going in chevrolets and fords. how many of those have you pulled up the wet carpet in when running wires. what hapeens to mdf and glue when it sits on wet carpet. how much good is that fiberglass then.so yes i know your opinion on this already.

To put it another way .I have a security system on my house. I have never had a break in or anything before or after having it installed . Not one little wimper out of in 5 years. The police say i live in a nice neighborhood and crime is low in my town. noone in my neighberhood has ever been broken into.But its still nice to know its there.

and please do not take this as me saying you are wrong. because see i am assuming you are going to say i dont need to do this.(fiberglassing)
But the glass gives my customers a sense of security. And im all about making my customers happy and assuring they will never have one problem. This is why i see the need to fiberglass the inside of enclosures.

thanks for the question. and the round about compliment . i think.

 

the first glass enclosure i built was just the oposite. it was not thick enough and flexed like hell, it sounded awful. that was 13 years ago. i learned an awful lot since . and im still learning. i try to keep an open mind.

i guarantee your box sounds great. and i honestly think you did a tremendous job for your first glass box. i bet if you did a poll . not one other persons first glass enclosure was that nice. not even close. i also like your references to math in a lot of your post . Math is pretty much all we do. its some skill, but the skill would be nothing without math.

 

Hey Tech!

I understand why you glasse them, Aint a dam thing wrong with doing it either. From a durability standpoint, it makes sense, no doubt. And i was complimenting your enclosures BTW.

Generally whenever i did it, I glassed the inside also, but in damp or wet enviorments, I also prefered to just paint the resin onto the exterior of the enclosure to prevent the penetration of moisture into the wood.. This was virtually 100% effective in all but the most demanding situations. The only other "possible" benefit to the painting resin onto the externals of the box was the fact that it did seal the box 100% airtight, although this along with matte on the inside never made any sonic differences in the system from the tests i run years ago.

Good job Tech, you do some fine work.....

 

thank you . i do appreciate the compliment. it sound like you are like me . i do not like just taking other people word for it . so i test stuff as well. way to many audio myths out . there like 2nd batteies , caps . effiecency ratings and ils rating to name a few. you guys seem to know your stuff ( you and ranger). quality audio has really suffered in the last 5 to 10 years. one of the biggest reasons are all of these so called audio schools. that are sending installer out in the real world with a mecp patch on there sleeve and no real world training. but yet you hire them to find out they can fiberglass o.k. but cant wire a relay to do anything. and god forbid you try to teach them something , because the school already taught them everything. your 15 years installing means nothing. they read the book, took the test and they are certified to know everything now. its got to the point that now before i hire a guy. i will toss him relay and ask him to wire me a starter kill circuit that with blow the horn when someone tries to start the car. assuming the horn is positive voltage. out of 40 to 50 people in the last 5 years 2 have gotten right on the first try.

or i could just be a getting old and grumpy. lol and my knees hurt.
