Box Build for IamDeMan

[W8 a minute 10+ year member]

Nice. I probably shouldn't say this but I always find slanted boxes aggravating. No matter how many times I measure the angle of my blade it never ends up "on the money" and is a couple of degrees off. I always end up using scrap wood to set it perfectly.

It arrived today. DHL struck me on this one. Not a packaging problem as fish did have protectors on the corners but DHL still manage to mangle a corner. It isn't devastating and I can mask it a bit, plus it won't really be seen when installed. Here are the pics of how I found it though.

And here is the bad corner.

Here is the sexiness that is called Mag installed in this bad mutha.

Now I got to finish my doors and get this shit installed.

Man they managed to ruin it on the front, regardless it still looks nice.

Indeed, at least it was bottom and won't be seen too easily. the lip where the seats fold down should hide it for the most part, but I am gonna pound it gently and spray a light mist of flat black to blend it in so wood isn't really seen.

Additionally I'd like to say this build is top notch as always. I felt around all inside seams and this shit lines up and isnt caulked up to hide. Fisher has the tools and knows how to use em. I was worried about matching seams inside perfectly with this angle and 3 walls in a sense plus my time is lmited. That was my reason to give fish some business. He doesn't dissapoint and is well worth his price f admission.

Here it is fitting in the trunk like it was meant to. It is just small enough to pull in and out through the trunk lid. No need to go through seat opening.

we have some type of cardboard corners that we wrap our product with when we ship it

dude that looks killer

Build looks great, but really, the inside port wall needs to be slanted as well to keep the port area constant throughout the enclosure.

It's too bad DHL ****ed up that corner; it still looks very sexy installed!

I have never heard this to be true. The math adds up and tuning is correct. I don't see how slanting the other end is necessary. Is like slash cutting cylindrical ports. As long as the length through the middle is correct then the tuning is correct.
Yes it does look sexy installed //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

He had corner pieces.

measure from the top to the end of the port, then the bottom to the end of the port.

with it like that you'll get two different numbers.

to maintain tuning they should be the same length, it probably not enough difference to notice. but with each piece being a different length it makes sense.

No you dont

Its like having a bend in it to begin with. the outer length isn't the same as the inner part of the bend. It is the measurement in the middle which is going to be the "median" of both numbers that matters. Continuity in a port isn't what dictates tuning. It is the sq area vs the median length that dictates it. It doesn't metter if you use 45*, 90* bends or slash cuts. As long as the median length is correct then tuning is spot on.

im well aware of sq area and length.

but with length alone it would seem to make a difference.//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

something just seems a bit off with not having the slant and not maintaining the same port length. its not like only the middle of the port is being utilized, its the whole port i dont exactly understand how the few inches that are left off/added at the top/bottom wont effect the tuning whatsoever.

not arguing with you at all, im just interested in finding this out

Continuity in a port isn't what dictates tuning. It is the sq area vs the median length that dictates it.

Actually, it's the air mass in the port and the surface area of that air mass that matters, not the length. The length is given to you once you know the correct surface area of the air mass. You know the tuning with the mass of the volume of air and with the surface area. When you know the tuning, you know how much air is needed. That is then turned into the correct length you need. Without the slant on both ends, the air mass calculation will be off and thus, your tuning will be slightly off. It won't vary much but it will be off some.

Exactly and the mass will be correct provided the MEDIAN length and area is correct. Which is why I worded it that way. There is nothing in the formula that says continuity has to be kept or that it has to symmetrical. The mass is correct plain and simply put. The calculation is NOT off. It is still the desired mass. Having a slant at one end or a bend in it doesn't change the equation //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif My median length(average of longest length and shorted length) is still the desired measurement making the total mass correct. It's basic mathematics. It is probably easier to tune with both sides having the same degree of angle, but it isn't a necessity to achieve the same desired results. Just involves slightly more figuring.

If what you are saying were correct, then my internal volume for woofer cavity would be off too because the top has less length than bottom, so it throws off the equation slightly. It makes no sense whatsoever. Mass is mass no matter if lengths on all walls is same or not. You add them up and you get a number.
