I talked to Steve at DD the other day, and he said for best results go by their box suggestions. http://www.ddaudio.com/dd/caraudio/enclosureInfo/boxSize_hiEff.asp Hope that helps, Ben |

Silver Member Username: Night_mirageAmmanJordan Post Number: 488 Registered: Jan-06 | Thanks Showrides .. I read all of these . But 4 now i'm just asking Did i build the 2nd one right ..? And what is the Diff between them ..? Thanks MuDDy , I don't know what's better , I prefer 2nd one cuz my trunk is hard to hear . THe Bass disappear in my car's Trunk , Maybe cuz its Benz , So i would like to do the 2nd one , cuz i can make the end of port connect to my factory subwoofer hole . Did u understand what i want to do ..? And 4 sure i want more SPL cuz i have 2 DDW6.5 in my rear door , So i want more bass coming from my car's trunk .. |

Silver Member Username: Night_mirageAmmanJordan Post Number: 489 Registered: Jan-06 | And BTW , I can n't Do more than 2cuft .. Thts the Maximum area i do have . And DD's says 40Hz You made 35 - 30 Hz |

Silver Member Username: Night_mirageAmmanJordan Post Number: 492 Registered: Jan-06 | I have these Dimensions  |
|
Gold Member Username: Basshead86Google is your Friend, FL Post Number: 6150 Registered: Aug-05 | you wont get the lowwww bass with 40hz....you will get some b/c of DD's stiff suspension being able to play under tuning a bit before bottoming out....but if you are running anywhere near 1000wRMS....watch the low bass songs at full tilt with a 40hz tune |

Silver Member Username: Night_mirageAmmanJordan Post Number: 496 Registered: Jan-06 | Thanks MuDDy . What Do u think 30 - 35 would be better . I said 40 cuz DD's says that , As i said in my 1st thread about my box last week I don't know much about building box's . And i ment Inches , What do u think this would be , Its a dimensions .. I draw my Dimensions and i u know every thing MuDDy . What Box do u prefer . I want it very loud , Cuz the Bass will come from my Trunk . And i have DDC6.5 , (2)DDW6.5 . and (4) 6x9 pioneer's speakers (I will change them later maybe for Some Infinity's ) . So i don't want mush SQ from my Subwoofer . 4 Thats the I choosed DD's Sub . Can i build my box (Circle Port) from that site ..? i prefer that over normal port .. What do u think ? |

Gold Member Username: Basshead86Google is your Friend, FL Post Number: 6226 Registered: Aug-05 | i would go with 35hz...i will get louder than 30hz, but it will play lower than 40hz... you can definitely do a circle port....you will need to use this website. http://www.carstereo.com/help/Articles.cfm?id=31 i owuld build a box that has 2.5 cubes after port area(the circle ports) and use 3 4" flared ports. they can be bought at partsexpress.com i think or maybe the www.realmofexcursion.com store too. |

Gold Member Username: Basshead86Google is your Friend, FL Post Number: 6227 Registered: Aug-05 | if oyu have a box that has 2.5 cubes of airspace AFTER the port displacement...3 4" flared ports @ 10 inches long(i calculated that with 2.5 cuebs and 3 of them they will need to be ~10.08inches long) will take up .21 cubes of airspace so build a box with internal dimensions of 2.81-85 cubes of air stick the sub in(i accouinted for sub displacement) and stick the flared ports in. and you will have a box tuned to 35hz |

Silver Member Username: Mike17362Durham, Nc Usa Post Number: 115 Registered: Sep-06 | off the subject for a sec what size box should i build for a guy for two dd2515 and what should i tune it to? he wants to do good numbers on the meter and have good sq,low bass, and loudness. |

Silver Member Username: ShowridesHartford, CT USA Post Number: 357 Registered: Feb-06 | I am going with Muddy on this one. DD suggests 40hz, and honestly, that would probably still sound real good for 90% of music. Even though is higher than you would want to tune most subs to. I would say 35hz would be a great comprimise. Since I don't think you are going for 100% SPL, you will get better lows when tuning to 35hz. So it all looks good to me. And the flared ports look good to me as well. Nice job muddy. |

Silver Member Username: AdddisorderWest palm, Florida Post Number: 876 Registered: Jan-06 | one thing though if you use those flared ports and use 3 4" in 2.5 cubes each port needs to be 30" long not 10" |
|
Gold Member Username: Basshead86Google is your Friend, FL Post Number: 6237 Registered: Aug-05 | i believe that is total accumulation of lenth....maybe i am wrong. i though when you used multiple flares in the calculator you simply divided the figure by three. not sure... however...with the same port area with a slot port, the length is about the same...so i think you do separate it between the flares....that is a good question though...your probably right. lol thanks ben |

Silver Member Username: Night_mirageAmmanJordan Post Number: 497 Registered: Jan-06 | WooW WooW Whats that . Thanks very very much guys 4 helping me . I will start building mine but is there any number of MDF wood . or its just MDF . I think there is sizes . And how many circle port i have to do ? and what lenght in box and out box .? I know maybe my Questions would be silly but as i said , Here in my country there is no one know's about dimensions , they build a saled box and without any dimensions , JUST LIKE THAT .. So maybe i'll need more help . Sorry . |
|
Gold Member Username: Basshead86Google is your Friend, FL Post Number: 6251 Registered: Aug-05 | get 3/4 inch MDF... and i am still trying to figure out the flared port length. i think mat is right. so you will need to maybe put them outside the box...which is better for turbulence anyway |
|
Gold Member Username: Basshead86Google is your Friend, FL Post Number: 6252 Registered: Aug-05 | i dont mean better as in makes more....you know what i mean guys. |
|
Silver Member Username: Night_mirageAmmanJordan Post Number: 498 Registered: Jan-06 | Nothing Inside the Box . Just about 30" inch out the Box ???? |
|
Gold Member Username: Basshead86Google is your Friend, FL Post Number: 6258 Registered: Aug-05 | yup 3 4" flares...that are each 30" long then your box only need to be like 2.6-65 cubes |
|
Silver Member Username: Night_mirageAmmanJordan Post Number: 499 Registered: Jan-06 | MuDDy Can i Build 2.6 cubf with my dimensions upside I don't have more than 22 inches for high how can i do 2.6 1 cuft = about 28 cm = 13 inches ?????????? or it does n't matter if its just for Width and Lenght .

Gold Member Username: Basshead86Google is your Friend, FL Post Number: 6266 Registered: Aug-05 | 1 cubic foot is 1 foot by 1 foot by 1 foot. or 12 x 12 x 12. you can get like 25 cubes out of your dimensions!!!lol |

Silver Member Username: AdddisorderWest palm, Florida Post Number: 887 Registered: Jan-06 | yeah the problem i had wne i was going to port my box with 2 4" ports is they had to be like 24" long i think so im like dammmmmn so its stilll sealed right now ill port it eventually |
|
Silver Member Username: Night_mirageAmmanJordan Post Number: 506 Registered: Jan-06 | Ok mat So u think doing a normal port is better and easier than circle port .. |
|
Silver Member Username: AdddisorderWest palm, Florida Post Number: 904 Registered: Jan-06 | well if you are good at wood working and have the tools to make your own box and think you can do a good job on the port then that would be a good choice. however if you are a little shakey the circle or aero port would be easyer. im not exatly sure why muddy reccomended 3 4" ports. im pretty sure that would be over porting you sub and lower its preformance. you should be fine using only 1 4" flared aero port. you shouldnt get any port noise i have talked with a bunch of people about using only one with my dd 3512 in 2cubes and they siad it should be fine. http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=268-352 ^^that is a good link for buying them if you need to know how long it should be let me know your box size and ill figure it out |
|
Silver Member Username: Night_mirageAmmanJordan Post Number: 507 Registered: Jan-06 | My Box would be 2.5 cuft @ 35Hz . All of this port would be out of box ? Nothing Inside . ?. ? |
|
Silver Member Username: AdddisorderWest palm, Florida Post Number: 908 Registered: Jan-06 | 7.9" long I belive that is not including the flare but im not positive. you can put it inside your box or outside. inside would probly look a little better. but youll need to calculate port displacement into your 2.5cubes |
