I need everyone's input on my box design
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10566 Registered: Oct-05 | here is a pic of my new box design. i already stated on it. i have the sides and bottom already cut. before i start cutting wood for the port i just want to know what everyone thinks. the box specs....... 6.2 cuft after driver and port displacement 154 sq inches port area. 4" x 38.5" tuned to 36-38hz. the pic you see is a side view of the box. the port will go across the back part of the top of the box. the port will fire in to the rear window.  |

Are you going to put one of those new DD 18's in there? Cuz that box is huge. I think with your new batteries and this box you're gonna hit 150+ for sure. |

Silver Member Username: The_image_dynamicSan Diego Post Number: 415 Registered: Dec-06 | good point... |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10567 Registered: Oct-05 | yeah rob. that is exactly what i am hoping for. it will reflect well cause my rear windshield is solid as a rock. lol. i hope. brad that will be for 2 btl 15s. each driver will get 3.1 cuft each after displacement so it just barely meets the requierment. |

Silver Member Username: Adam_s15 TC9 Hybrid, RE MT Softparts Post Number: 716 Registered: Aug-04 | Looks good. Just hope it actually works out as good as it does when you designed it. |
|
Gold Member Username: Th3pwn3rChicago, Illinois U.S.A Post Number: 1110 Registered: Jul-06 | And OMG again^ He spelled COMMA wrong. I'm falling apart |
|
Gold Member Username: Th3pwn3rChicago, Illinois U.S.A Post Number: 1111 Registered: Jul-06 | Chad you might actually blow your back window out of the seal lol...it's pretty possible too lol. |
|
Silver Member Username: Adam_s15 TC9 Hybrid, RE MT Softparts Post Number: 718 Registered: Aug-04 | Yeah Chad you should be carefull you might break the window I have heard about L7s that shatter windows.  |
|
Gold Member Username: Matt12490California USA Post Number: 1754 Registered: May-05 | I'll give you $1 if you break the back window. |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10568 Registered: Oct-05 | i hope it doesn't do that to my back window. i don't want to replace the back window. ^^^^i ran that through microsoft word and no mistakes in spelling or grammar. so screw you rob. rofl. |
|
Gold Member Username: Matt12490California USA Post Number: 1756 Registered: May-05 | Wait, is this a box that you're hoping to get to 150 with? Tuning is a little low, I would think it's a daily driving box? |
|
Gold Member Username: Th3pwn3rChicago, Illinois U.S.A Post Number: 1114 Registered: Jul-06 | "meets the requierment" There's one for starters  Aren't you supposed to capitalize the word "I" ? Got ya! |
|
Silver Member Username: Adam_s15 TC9 Hybrid, RE MT Softparts Post Number: 720 Registered: Aug-04 | Rob is all about correcting spelling and grammer lately. lol |
|
Gold Member Username: Th3pwn3rChicago, Illinois U.S.A Post Number: 1117 Registered: Jul-06 | Nah...I only do that to Chad lol. |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10569 Registered: Oct-05 | lol. yeah its all good. me and rob go way back. rofl. rearrangeyamind.......i know it is tuned a bit low for spl. but i am hoping the port area compensates for the low tuning. also i am mainly trying to be in the 140-149 bassrace class. i am hoping with this new box i can score around 146-147. |
|
Gold Member Username: Matt12490California USA Post Number: 1765 Registered: May-05 | I'm not into SPL and comps so disreguard this question if it's stupid but.. Why not tune it high AND have a large port area? Ooh and you can call me Matt |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10570 Registered: Oct-05 | i still need it for daily as well "Matt". lol. as long as i am close or at 150 i will be fine. like i said above though, i want some killer bassrace score. btw i think ima tune it to around 38hz. |

Gold Member Username: Extrmndor3IF U HEAR ME... I GOT KING K... Post Number: 3901 Registered: Feb-06 | since u got the set up in the seats ill do like a wall, since ur 50% doing that. go ports firing to the widnshield and do flared ports too but the big ones u might ask marshall white to make you some 9INCH ports, then when u have the box use another mdf panel to make it like a wall so no air or pressure can go in the back. |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10575 Registered: Oct-05 | thought about flared ports kingrob but it won't have the clearance for the length. how about this way guys.  |
|
Silver Member Username: Adam_s15 TC9 Hybrid, RE MT Softparts Post Number: 721 Registered: Aug-04 | I think either way isnt going to be that much different. Stick with the first one and get a little more volume lol. |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10577 Registered: Oct-05 | yeah i like the first one myself. |

|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10578 Registered: Oct-05 | ^^^^^f@g with his "hmmmmmmm......." rofl stfu man. quit trying to sound like you are a professor or something. lol. |
|
Gold Member Username: DrivingrecklessDD 9515f, USA Post Number: 2993 Registered: Apr-06 | idk man just pondering that design but hell worth a try but like rob said if your windshield sucks your gunna get a hell of a leak |
|
Gold Member Username: Extrmndor3IF U HEAR ME... I GOT KING K... Post Number: 3905 Registered: Feb-06 | wall if u can get 9 inch the lenght wont be too much problem. i can get like 4 9 inch instead of the 4inch ports. wat u can do its to make a flare but slot poter but will be too hard. u can do that desgin u have. but make sure its all firing to the front. so the pressure goes directly to the mic like i siad try makin someting for the box like a panel for the box makin the air keep going str8t to the mic and not escape to the back |

Gold Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 3872 Registered: Sep-04 | I'm wondering if less port area and more net volume would be better...? |
|
Gold Member Username: Th3pwn3rChicago, Illinois U.S.A Post Number: 1120 Registered: Jul-06 | It's all trial in error and for his goal in SPL he's going to have to keep testing and he will find what works. |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10580 Registered: Oct-05 | i am trying to go with less net volume so less imp rise. |
|
Gold Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 3875 Registered: Sep-04 | to be honest i think you should have gone with a single 18 BTL... its obvious you struggle working with those 2 15s. hope you hit your 150 though. |
|
Gold Member Username: Th3pwn3rChicago, Illinois U.S.A Post Number: 1126 Registered: Jul-06 | I told him to go with 2 18's That would have been a tight squeeze. |

|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10583 Registered: Oct-05 | i would kev but if i do that, i would have bass waves traveling back. by doing what i am doing in the first pic, its almost like its in the rear corner of my car so all the bass waves have no where to go but forward. |

|
Silver Member Username: Bump05CashMoney, 15 Hd3 USA Post Number: 962 Registered: Aug-06 | that's what I said port and sub firing forward the mic is so close to ur box, I think it will be best bet less trapped air in the back ;) |

Silver Member Username: Tremor1127You aint wangin till y... Post Number: 946 Registered: Aug-06 | that box should rock... if i was in your situation i would def try something like that... its the same concept almost as a crx box but it starts flowing at your back glass... |

Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10588 Registered: Oct-05 | hmmm interesting idea. well if i build the box and i don't like the result, i can stand it up like that. it should just fit so it will be like a semi wall. |
|
Silver Member Username: Tremor1127You aint wangin till y... Post Number: 947 Registered: Aug-06 | but for big numbers, its up to you... i just think it would be a killer daily box... |

Gold Member Username: Van_manBoston South, MA Post Number: 2033 Registered: Mar-06 | Im just messing in paint. I dont know what effect it will have. But If you build it, try it a coulpe of ways. I notice diffrences when I move my box around. I have tried it in 6 diffrent configs, and I can hear a diffrence in 3 of em. |
|
Silver Member Username: Bump05CashMoney, 15 Hd3 USA Post Number: 963 Registered: Aug-06 | marcs idea is better ;) |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10590 Registered: Oct-05 | you got a van marc. you can move your sh!t around anytime you feel like it. me once its in the car, thats it. lol. but your idea will work. i think i will do that at the comp. i am in the 1-2 super street anyways. |
|
Silver Member Username: Bump05CashMoney, 15 Hd3 USA Post Number: 966 Registered: Aug-06 | chad. lets get together one of these weekends and build u a wall, for real. you sh!t will be insane with a wall btw instant message me scizzles |
|
Gold Member Username: Van_manBoston South, MA Post Number: 2034 Registered: Mar-06 | Good luck Chad. |
|
Platinum Member Username: BestmankindWww.15inchwangers.comFI Audio BTL Post Number: 10595 Registered: Oct-05 | thanks marc. you are always so kind. building the box is the easy part. getting the box with the subs mounted in my car is a b!tch. |
|
Platinum Member Username: Rovin1 12 Atomic ... Post Number: 10784 Registered: Jul-05 | i'm no spl expert but somehow im not digging that firng rear concept y not keep it very simple & do like what i once did  - 2 subs in single chambered well braced box & 1 monster port = immense bassline ..... |
|
Gold Member Username: FrkkevinResonant Engineering..., Fort Worth... Email Post Number: 3210 Registered: Nov-05 | build it into the trunk chad.. won't have to worry about rear=-wave cancelation your going to have this issue no matter what design unless you built part of the box that slide into the trunk and ran ports directly up through the rear deck to reflect off the window... btw if your going to run the port to the back like that. fire the subs forward.. key is wave alignment and that would be best for that seeing port placement |
|
Silver Member Username: BudlingCali USofA Post Number: 219 Registered: May-06 | Driving, I could build a new box if I needed too. I was basicly expressing my jealousy for Chads continuosly changing system. |
