Box picture

you misunderstood it then.
i know they dont determine bond strength but anyone will tell you that wood glue alone wont hold up under the pressure, and you then get a blow out, better safe then sorry

but as he said the box is only a little over 2cf so he will be fine, if the box was bigger it would have been another story, the picture made the box look more like 3-4cf.

again wood glue and caulking wont hold a box together on its own. i would rather build a box stronger then needed then just enopught.

take my box for example, its 9.5cf, 1.5X1.5 (normally called 2x2's, 1.5 is after the milling and routerring the edges)in all corners, all joints wood glued and then fiberglassed W/matting in all corners then a layer of fiberglass resin to coat the box, plus screws ever 3-4 inches. the box is solid and i dont have to worry about box flexing or blowing out a side wall

you sir, are misinformed.

What's wrong with the paint job, I was just trying to paint the inside?? What makes the plexi a "choppy" mount?

you need to fire polish the edges of plexi with a torch to give it the glass appearance. Looks good.

Oh yeah ??, With Proper joinery , and clamping of the glued joint .I'll put $10k on it right now , that the mdf breaks before the glued joint does . been there done that moons ago my brother . Also resining the interior of a box adds no strength what so ever , just seals it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I find it very hard to believe that that small of a wire can cause port noise

I take extreme pride in EVERYTHING I build, install, or repair. I know the interaction of the cabinet to the electromechanical device to produce dubious amounts of sub range frequency response is the most important thing to you. However, the constructive criticism provided in this thread is for your advancement in the car audio industry. I have not meant to harm your reputation or say you CAN'T build a good box. BUT, I feel if you are going to post a picture then you are also asking for feedback on your work. Everyone has a different idea about what is right and what is wrong and I believe thats what makes this industry so exciting. Thank you to the people, like those posting here, and crazy wackos like David "fishman" Rivera for pushing the industry forward with new ideas. That, and the fact that it amazes me someone will go to all the hard work of putting a "system" together, take pictures, and not clean up the car, remove the candy wrappers, cigarrette butts, dirt, dust, etc. All I ask is you have a little pride... that's all.

No problem man, I am not getting upset or anything like that. It really doesn't matter that much to me. I do take pride in what I do, but building boxes for myself doesn't put any food on my table, it is just for my listening enjoyment.

you are going to hate me for this ....but.....

Your work is your signature! The box looks good and the sound/functionality is at least 95% of the job.

I don't mean to beat a dead horse...but... (pound, pound, pound)//content.invisioncic.com/y282845/emoticons/blackeye.gif.66a1670f5aaf7f406e783a63e3387dc5.gif

I am a, formerly, licensed plumber and electrician in the water industry. Most everything I did was within plain site in my customers homes. I am a perfectionist (read--"ANAL"--) and discovered people would request my services based on my previous installs (word of mouth). Hence-- I didnt have to look for work, it came to me. Even though I am out of the industry I still have people calling me asking me to do work for them. Anyone can screw pipe together, solder copper, or wire an electrical box... that's what I did... but I finished the work, all of my sweat fittings were wiped clean, all of my wires were bent at 90 degree angles-- overall the extra work I did din't actually improve the performance of the water flowing through the pipes or make the electricity flow with less resistance. BUT, the customer doesn't see the water in the pipes... he/she saw the installation and THAT is what made them request my company for future work, repairs, etc. and THAT is what keeps me busy to this day. Take it to the next level...It WILL pay off in the future...even if you are only building boxes for your buddies/friends.

So...what am I trying to say? It may not seem important to you, since it is just for YOU, but how many people are you going to show your work too? How many people have read this post and thought, "great box but I wouldn't let him do mine? " How many shops are looking for that next new 'talent.' This is such a competitive industry and you really need to make your work stand out if you are thinking about going anywhere in it. Personally, I would take your skills and be the next "fishman!"

I personally can't wait to see what you come up with next. you have the vision...now its all about getting the experience and taking constructive criticism to make your talents that much better! You are on the right track! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

No I understood perfectly. Case in point, I have made numorous boxs with no screws, to test strength in my early years of building boxs. Ranging from 1-3ft^3.

Never had a problem.

Screws are not required. Wood glue forms a chemichal bond between the two pieces of wood. The bond is as strong as a solid piece of wood. There will be no "blow out" if done properly.

Regardless, I normally always use screw just to hold the wood while it dries at the least.

If you are talking about bracing then you're on the wrong subject...

These people who are so adamant that glue alone won't hold together. It's especially worse when they say that anyone will tell you that it isn't strong. As has been said 5000x over, the actual panels will break before the glue joint does if it's constructed properly.
