|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3357 Registered: Mar-04 | looks pretty good, but whats the tuning? also, try going w/ 1 chamber...just my $0.02 |
|
Silver Member Username: John_washNashville, Tennessee Post Number: 540 Registered: Dec-05 | the port is 14.5 x high 3.625 wide x 20" long. this will make the tuning 35 hz. Does 1 chamber yield more spl or anything? I was thinking about goin that route at first but then i thought about bracing so i just designed it to be seperate chambers. |

Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3359 Registered: Mar-04 | here...try this 7.45cuft after all displacments tuned to 35hz.  |

Silver Member Username: DrsmithMontana USA Post Number: 674 Registered: Nov-04 | yeah marshall where did you find that |
|
Silver Member Username: John_washNashville, Tennessee Post Number: 543 Registered: Dec-05 | highest i can go is 16" though marshall |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3361 Registered: Mar-04 | run a brace from between the subs to the back wall of the box. two 1/2" threaded rods would work great! |
|
Silver Member Username: GrebnereonPost Number: 178 Registered: Mar-06 | well.....that means you need 2 12" sd2.5s  |

|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3362 Registered: Mar-04 | how bout this J-Dub, 7.35cuft net tuned to 35hz....79.25sq inches of port.  Kevin, its called Google SketchUp |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3363 Registered: Mar-04 | Chad...i love this program |
|
Silver Member Username: FrkkevinLake Worth, Texas US Post Number: 806 Registered: Nov-05 | Awesome.. I'ma dl it and check it out.. I can design in Bass Box Pro 6 then see what it looks like in SketchUp .. btw did you check out my diy ram air.. it excited me lol |

Gold Member Username: Safe_crackerChicago, IL US Post Number: 1589 Registered: Jan-06 | I thought there was about a 3db loss if the port wasn't located between the drivers? Polo.. |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3364 Registered: Mar-04 | no...the port in the center thing is BS. |
|
Silver Member Username: John_washNashville, Tennessee Post Number: 544 Registered: Dec-05 | U R DA MAN MARSHALL!!! Thanx alot. Im glad you cleared the port in the middle theory because i kept hearing what polo was saying about the 3 db loss. Thanx again mayne. |
|
Gold Member Username: Safe_crackerChicago, IL US Post Number: 1590 Registered: Jan-06 | You sure it is BS, anyone else out there confirm taht it is? Polo.. |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3365 Registered: Mar-04 | i'll put it this way...look at dam near ANY walled vehicles in dBDrag, USACi, ISACA....and any other SPL organization. 85% of them are 1 chamber, subs on passenger side, port on drivers. If i am wrong...there are ALOT of of SPL gurus that are wrong right along w/ me. |
|
Gold Member Username: Safe_crackerChicago, IL US Post Number: 1591 Registered: Jan-06 | LOL   |
|
Gold Member Username: B101Queen City, NC USA Post Number: 3569 Registered: Sep-05 | port in the middle isnt louder than port on the end of the box! SPL port to the driver side is loudest... its called loudin the mic... cause all that turbulance and presureized air rolls out the port behind the driver, to the corner of the dashboard then accross the dash and windsheild... No other position is actually louder than that... marshall is actually giving out alout of tricks, yea, common chamber, braced between both holes etc... |

Bronze Member Username: Phil_salisburyPost Number: 51 Registered: Sep-06 | Hmmmmmm, Now I wonder where marshall found out about SketchUp???? |
|
Gold Member Username: Safe_crackerChicago, IL US Post Number: 1593 Registered: Jan-06 | Phil we had it for a while but I never knew there was a pro. Funny thing the Sketchup I had was a Beta, I now found out it was the pro but free, lol. Polo... |
|
Bronze Member Username: Phil_salisburyPost Number: 52 Registered: Sep-06 | Polo, Yeah, I have the Pro version as well, I had for quite some time.;) |
|
Gold Member Username: Safe_crackerChicago, IL US Post Number: 1595 Registered: Jan-06 | But, did you get your pro for free? |
|
Bronze Member Username: Phil_salisburyPost Number: 53 Registered: Sep-06 | I'm a cabinet maker, I know alot of people, what do you think? |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3368 Registered: Mar-04 | I found sketchUP digging around on google...I downloaded 4-5 free CADs before i found one i liked alot. SketchUP fit the bill nicly for box designes. Some of the other CADs were pretty much worthless. |
|
Gold Member Username: Safe_crackerChicago, IL US Post Number: 1596 Registered: Jan-06 | YA, some are a pain in the @ss to use. This one was pretty self explanitary, all you had to do is play around with it which was quite fun! Polo... |
|
Bronze Member Username: Phil_salisburyPost Number: 63 Registered: Sep-06 | Before I discovered and acquired Sketch Up, I want through my different CAD programs that basically worked in 2-D and from the 2-D drafts I would then do 3-D drafts, but very basic 3-D's. The most user intense Cad software like autocad or solidworks that you did 2-d designs and could translate them into 3-d are all well and good, but the learning curve for such programs required to much time just to understand basic function. So, I just kept searching till I found SketchUp and after a few hours playin around with it, I had it knocked. And now, this is the only drafting/designing program I will ever use because I doubt someone will come along with a better program that easier to use. |

Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3369 Registered: Mar-04 | yep...i have been playing w/ it for awhile. here is a box i'm starting on fr a friends GrandAm this weekend. 2 L5 15's tuned w/ interchangable ports. They will fire into the cabin, but i only had 36" wide to work with.  |
|
Gold Member Username: BestmankindLos Angeles, CA USA Post Number: 5689 Registered: Oct-05 | damn i downloaded the program but it won't run on my work pc. ima try it when i get home. awesome idea marshall. you guys are geniuses. |
|
Silver Member Username: John_washNashville, Tennessee Post Number: 545 Registered: Dec-05 | Hey marshall how do those threaded rods work? I've never messed with them. |

Gold Member Username: Safe_crackerChicago, IL US Post Number: 1600 Registered: Jan-06 | Ok, I am starting to get the hang of it. Tonight I will crack on a new design for my car the alcohol will help later, lol. Notice how I am learning to make them aeros, hahahhah..Polo.  |
|
Silver Member Username: NoviceinstallerHere, There Post Number: 117 Registered: Sep-06 | awwwww......... but i liked yer old box |
|
Gold Member Username: Safe_crackerChicago, IL US Post Number: 1602 Registered: Jan-06 | Dude you will love my new one! Here is a hint, this is a VERY rough sketch still trying to get rid of the right corner for an almost perfect flow...  |
|
Gold Member Username: Safe_crackerChicago, IL US Post Number: 1603 Registered: Jan-06 | Will flow better with a slot port but I am not fond of them... |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3374 Registered: Mar-04 | J-dub, you drill a hole the same size as the rod in both the front and back wall of the box. You use washers and bolts to sandwich the MDF...inside and outside the box. this is what it will look like: inside box:  outside box:  |
|
Bronze Member Username: Phil_salisburyPost Number: 66 Registered: Sep-06 | Polo, I saw your mockup of the aeroports, so I thought you would like these:  |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3375 Registered: Mar-04 | anyone wanna try to build this???  |
|
Bronze Member Username: Phil_salisburyPost Number: 68 Registered: Sep-06 | Marshall, Sure, no problem, can't be any harder than building a octagon shaped tree stand planter out red cedar. The question is, are you or whomever willing to foot the bill? |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3376 Registered: Mar-04 | True...I would be hard, but now impossible. It would be a nice box just to have...kind of a "hey, look what i got and you dont" thing |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3377 Registered: Mar-04 | not impossible* |
|
Gold Member Username: BestmankindLos Angeles, CA USA Post Number: 5693 Registered: Oct-05 | okay i got one.  |
|
Silver Member Username: John_washNashville, Tennessee Post Number: 548 Registered: Dec-05 | preciate that Marshall. I've never built a box this big though. I'd imagine its a piece of cake. O yea, all i have is a skillsaw and a jigsaw. Will it get the job done. I was practicing my cuts not to long ago with my skillsaw and the edges were jagged. I think its the blade tho. What kind of blade should i get for very smooth accurate cuts? And where can i get some threaded rod? |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3378 Registered: Mar-04 | build a gate w/ a straight 1"x4" and 2 c-clamps. |
|
Silver Member Username: FrkkevinLake Worth, Texas US Post Number: 813 Registered: Nov-05 | Chad.. were you trying to make a train?! Lol.. just messing with ya but I have yet to have a lot of time to try to figure out everything.. I can't do no where near what some of your guys can do. I'll give this proggy a whirl though cuz when I tried to learn Autocad 2004 I flat out gave it up lol |
|
Bronze Member Username: Phil_salisburyPost Number: 70 Registered: Sep-06 | Best way to get the hang of the Program is to view the tutorials for it. |
|
Gold Member Username: BestmankindLos Angeles, CA USA Post Number: 5694 Registered: Oct-05 | phil did you get my email? |
|
Gold Member Username: Safe_crackerChicago, IL US Post Number: 1604 Registered: Jan-06 | Phil by the time I make one of those aeros on sketchup I can make a real one, lol. Seems everyone is getting the hang of this nice program? Hey Chad that looks like Reck's box, lol. Polo... |
|
