Okay guys, here it is the long awaited and anticipated (at least for CSU87) box calculator for excel WITH CUT & DESIGN SHEETS!!!!..... Now the cut and design sheets are simple and in their infancy but it's all working and complete..... I hope....... here it is for all to try and let me know any problems you find and they'll be repaired ASAP...... And if all goes well it'll become an executable..........



Have fun and enjoy!!!

Ill giver a try now, didnt understand the layout all to well the first time around

Edit: the only thing I dont really get, is how come the 256 port area number never changes? Looks like some solid math and matches up with my current box anyways.

ALso wheres the cut sheets? Not that I would use them but I didnt see it on the page anywere

if you're talking about the port area number by where you enter the box size it will only change if you adjust stuff for the Round port, the port area for the SLOT port is down in the slot port area......... the cut sheets are on the tabs at the bottom...... named for each type of box to build......

I just took another look....... I can't see where the port area numbers aren't changing for either type...... wish i could see ur screen

Also for anyone who hates to change decimals to fractions i have one formatted here with all the box and cut measurements to be by the 16th of an inch..... it will only do one so you'll have to divide it down for 8th's 4th's and halves but that's not too hard....

You put work into this.
I gave it a quick run and it's nice and the values calculated look right.
Thumbs up to you.
One thing I really didn't care for were the "Golden" cut sheets. IMO they were kinda useless and would confuse people. I know what you meant by showing them but are not neccessary.
Just take those out and you are good.
I for one will use this. Easy to use.

Thanks man....... the whole thing started as a tool for me to try to save some time, the Golden enclosures were what I was wanting to use but the formulas for it were a pain to redo every time I changed a parameter on the box. That's how this whole thing started, I just left them there since it was the original purpose for the sheet.

Thanks, I'm pretty sure it will help make it easier to design it for you. However, I take no responsibility for enclosures that end up not working correctly.... LOL

props to you man

Thank you... Yes the ergonomics are a little bizzare, like I said earlier it started off just being an easier way to figure those **** Golden numbers boxes. Once I hear back from enough people that everything is solid I plan on turning it into an executable and it will be MUCH more ergonomic and the flow will be much better as well.

Thanks to everyone who's downloading and giving it a try. When I saw how handy this tool could be if built right I decided to share it. Try it, abuse it, find the flaws and together we'll turn it into something that anyone who's building their own enclosures may turn to and save themselves some time and hassle.

Would only be for the slot port. I plan on building my box out of 1" thick MDF...I don't see a reason to build the port with 1" thick as well

The pressures will be the same on the port walls as they will the on the enclosure walls, seems to me you'd want them to be same as the rest of the enclosure..... A chain is only as strong as the weakest link...... I mean the port walls inside the enclosure are almost like the walls of the enclosure itself, with the pressures being reduced only where they flow through the port itself.....

first of all, did you make sure you had downloaded the latest version of it..... the links in place now are the latest, if you downloaded it before the 18th then that version does have a cut problem as I stated above.... also, i'm gonna work with you as best I can..... I'll send you a PM and we'll go over the numbers......

07-20-2009, 05:09 PM
does it include how many woofers? or putting the port in a different spot? cause i have a truck, and i was thinkin about puttin the port on top, but not all the way on the left. moreso center. but that might be stupid? lol

in any case subs forward, andport on bottom, curving to the top? would it change sound?

as i stated in the PM..... no need to change the port area..... by changing the tuning frequency up to 32 from 30 it reduces the length of that #2 inside port wall a whole 4 inches and makes it clear by a long shot...... you didn't mention what sub you're building this for but if it has great excursion capability then you may well need the 16sq in.......

it does it by the sub displacement..... if you're using subs that have .16 cu.ft. of displacement like the Fi 12Q for example then just enter .32 and that cover's 2 subs, or .64 for 4 subs, etc...... the sub can be mounted on any wall of the enclosure you choose except the back one on a slot ported enclosure so that choice is yours as long the the panel is big enough for the diameter of your sub....... now centering.... well...... it's not that advanced yet...... but with some more time and maybe a little help it could have the capability of giving the port an offset from the side........... and to answer your final question as far as the relationship of the port to the subs NOT including the vehicle environment, no that won't have any effect on the sound at all...... now once it's in the truck and the inside of the cab is in play..... well..... i'm no acoustical engineer so i can't say for sure...... may just have to build it and see.....

There could be bigger things at play in that case..... if he has a car with a trunk and the box wasn't well sealed it would play havoc with the sound in your truck but not be nearly as noticable in the trunk of the car....... things like that can cause big problems when the enclosure is sharing airspace directly with your ears, in the trunk of the car the air gets pressured up and the sound waves have to travel through the back seat and rear deck to get to your ears which can mask problems........

I sold a tube enclosure I built to a kid once and he brought it back the next day sayin' it didn't work and sounded like crap in the back of his blazer... a quick inspection and the sub wasn't fully seated against the face of the enclosure and was leaking air badly..... a little trim to the cutout and a light layer of silicone and BAM, it was boomin' along just fine.... leaks can REALLY hurt the sound......

how old are your versions of EXCEL? The file itself is not password protected it can be opened by anyone, however the sheets are protected from being changed to protect my work.....

I'm not sure what's going on there but I just tested opening it with both EXCEL 2003 and OpenOffice Calc (OpenOffice is a free Office Suite that can work EXCEL sheets) from the download site and had no problems....... you might try downloading OpenOffice its FREE and works just fine...... I have no idea what the options question box was about unless your versions of excel just don't like the circular references....

I'm glad to hear you're giving it a try! If you run into any problems with the cut outs just send a PM and I'll do what I can to help you out..... For Teen it turned out all he needed to do was change his tuning and cut the #2 port wall down 4"..... I'm going to make some changes so that it will tell you if there's a problem with the port length and the enclosure size soon.......

Otherwise it seems everything works pretty well in it so good luck and enjoy. I can't wait to see the results!

All the blue cells are protected to protect the program itself from someone messing up a formula and then distributing it to some people then them coming back to me and saying that it don't work.

It explains in the prologue at the top that the RED numbers are the ones you can change to enter the variables you need to design your enclosure. It shouldn't have any problem letting you change those.

Are you entering the same dimensions as the Golden Box into the Custom Enclosure dimensions?? If so the 2 or 3 thousandths of an inch difference isn't enough to cause any problems, anything you use to measure your cuts with will be much farther off than that. Otherwise, yes the Golden numbers will ALWAYS be different than the Custom Numbers, the Golden numbers are calculated for you, the Custom Numbers are mostly entered by you. If you can fit the Golden Numbers box into your vehicle then do so, that configuration is basically an "Acoustically Perfect" box. If you can't fit it then use two of your maximum dimensions and it will give you the third one, for example, if you have a trunk with a max width of 36" and max height of 19" like my brothers car, and you're looking for a 8cuft box (like he is for his SSD 18) then it will tell you how deep the box will need to be for whatever port size and configuration it is that you choose. It's all really just as easy as that, then just go to the tab for the box type you're figuring for and print the cutout dimensions. I'm working on streamlining the interface of the program to make all this stuff much easier to work with.

Okay, since no one else is telling any tales one whether or not they've used the program for actually building any boxes and discussing how they've turned out I'll be the first to do so..... first of all my buildlog is here: http://www.caraudio.com/forum/showthread.php?p=6562175#post6562175. The box will be 5.65cuft total, 4.2 after all displacements. The port is 15.5x3.75 and 24" long tuning to 32Hz. Here's some screenshots of the design on the program.

http://i889.photobucket.com/albums/ac98/altoncustomtech/BuildLog/mainscreenshot.jpg

If you notice here, I used a port area of 13.92sq.in. One of the beautiful parts of the program is that you can instantly see changes when you want to try something. The enclosure is good with 12 to 16sq.in. of port area per cubic foot of size for these subs. I adjusted the area of the port so that I could get good even numbers for the dimensions of the enclosure and its right in the middle of the recommended size.

http://i889.photobucket.com/albums/ac98/altoncustomtech/BuildLog/cutoutscreenshot.jpg

Here you can see the given # for the port width is 3.772", I rounded this down to 3.75" as 22 thousandths of an inch difference will not really be noticable, besides the port wall length was shortened slightly which should get the tuning back to square. Otherwise as you can see all the rest of the numbers are nice, even, easy to measure and cut which makes this program REALLY handy.

There's mine, post yours.. I'll have the box done this week I hope and I'll give a good review on how well it works out. Thanks for following along.

The "GOOD" display there I put in there originally as a checks and balances system to be sure that the math was adding up. As I said before I'm in the process of rebuilding the layout of the program and this will be gone, however, it WILL still tell you when you enter something wrong like putting numbers in all 3 dimension boxes since in almost all cases the resulting volume will be incorrect compared to what you said you needed to start with.

The gross is the TOTAL gross volume, that's subwoofer displacement and port displacement including port wall as well which has to be added in too, plus you can't make a TOTAL gross volume calculation using the EXTERNAL dimensions.

Here's the link for the standard version:http://www.mediafire.com/file/w3mymgzmhkd/Box Calculator.xls

For those who hate working with uneven "thousandths" of inches, here's a link to the version with fractions. At this time Excel can only round to one fraction at a time so all numbers are in 16ths of an inch, this means that .5 (1/2) inch will look like 8/16.

UPDATE....

The new sheet is coming along well, I've removed the "Golden Numbers" enclosures. Along with the rectangular style custom enclosures like before it has design parameters for WEDGE shaped enclosures as well with customizable angles for the front to match up to any angle you want such as the back of your back seat. I have even added a TUBE enclosure for the person who occasionally builds them, I did it cuz it was easy to add and would make that particular calculation much faster. Right now I'm also adding a sheet with a box size calculator for those who have the BASIC theile/small parameters and are looking for a volume suggestion. Another addition is buttons at the top to make changing from the calculator's to the cut sheets a simple click and finally a HELP sheet at the end to hopefully answer some FAQ's when using the sheet. That's about it, lots of changes, some tighter calculations, and I'm trying to add more of the more common designs. If anyone has ANY suggestions for things they'd like to see in the program PLEASE let me know, it's impossible to build something to suit the majority needs if I don't know what the needs are.

Works great man.


Any chance you've built a box by it yet?? I have mine built but haven't had a chance to test it yet as work has had me tied up...

Works great! I just used this sheet to design/build a 1.8 cft @34hz for my 2 HX2 8's, sounds awesome!!

Now that's helpful! Thanks for letting me know!

I've been quite worried since no one else has posted anything about their exploits with it. I have my box built but haven't had time to finish it so I've still not gotten to hear my Q's yet :(

That's great to hear, I'm really glad to know it's working well, now all I have to do is find the time to get the new one completed and we'll all be the happier...

honestly... I build a very similar application ~4 year back in excel..

Your math seems to be good, but the usability is difficult (I had a hard time figuring out how to use it, let alone get it to spit out what I was looking for). When I did however, like I stated, the math was good.

I dug up the app I wrote... it looks like the following...

if you want to merge them.. or some input on formatting... let me know

Damm... looks quite nice.......

yeah the old version can be difficult to navigate, the new one should be much easier for everyone to move through.... I like the cleanliness of your sheet, it's cut dry and to the point.... Having the addition of the ability to input 2 given dimensions on my sheet adds to the clutter I think, but it makes changing box parameters very nice indeed and takes the guess work out of what it takes to fit the vehicle...

I appreciate the offer... Let me get the next version out for everyone to play with and we'll see what needs done after that.... Thanks too for verifying the math!

So is the link you provided in post #1 the updated version of the calculator??

No....... the new version is not posted up yet, I'll start a new thread when I do. The new version looks only a little like the old one as far as the BASIC format, it is laid out better and easier to navigate between the tabs, with added box shapes and such.

I DL'ed the program, but I keep having my blue numbers in the box calc. page read, "#DIV/0!

I have all red areas filled in and my status is, "GOOD". What am I doing wrong?

I haven't finished my latest box but I used this calculator and used the 'golden' spec. I should know how it sounds next week.

If you can get me a screen shot i'll be able to help alot more..... but when it comes to the custom enclosure calculator only 2 numbers should be filled in, it calculates the third one for you, that could be the problem if that's the case..... its late and i'm having a hard time thinking or recreating the problem... but it's for sure if you can shoot me a screen shot I can most likely identify the problem....

Haven't bumped this in quite awhile... I've finally found the formula I was looking for for the Wedge shaped boxes so the next version will be posted right after I get the amp rack and box done in the van (work is such a pain!)...
