I hope it works out for him and doesn't look too bad atm. It was the frst time I used that particular box designer. I always used BB6P. Keep us informed, Ben.. I am gratefull that you would use my advice, ect... I love this site. lol |

New member Username: Michaelb1100Louisiana Post Number: 9 Registered: Apr-09 | I have a question here, Kicker specs unless I am reading wrong and I don't think I am because I am looking at a picture :-) says 1 - L7 needs 3.25cf at 37hz with .33cf of port volume. How big is your box? Also how would I drop the hz from 37 to 32. |

Gold Member Username: Hittin1TEAM REVOLUTIONLake Charles... Post Number: 3166 Registered: May-07 | you are absolutly correct that they need that for the SPL vented enclosure. I fixed him up to specs with the "compact vented specs" as he was needing with the limited space and max dimentions that he provided. I agree with tuning lower than kicker specs, but I wanted to stick with kickers specs because it is not my setup. 1.75 ft3 (49.6L) + port displacement 2.5 x 13.25" (6.4x34cm) port, 22.5" (57cm) long Power Handling = 600W RMS straight from their manuel under minimun vented enclosure. |

New member Username: Michaelb1100Louisiana Post Number: 10 Registered: Apr-09 | Ok Question, I am building my box to Kicker specs but want to tune for 32hz not 37hz, the box will be 3.25cf, how do tune for 32. Is it just adding length to the port? If so how much? |
|
Gold Member Username: B3n07Louisville, Ky USA Post Number: 1051 Registered: Jul-07 | ok so i finished the box installed it Saturday drove around a little and went to the shop today an im kinda of depressed all that work to gain 1 db not im hitting 137.6 on music at 53 hrtz. what am i doing wrong. i was gonna try the elevator from Flo-rida but i can find a good copy |

|
Gold Member Username: DeadrabitMarionville, MO Post Number: 1716 Registered: Jun-07 | use this http://www.carstereo.com/help/Articles.cfm?id=31 that pretty much tells u how long short or anything u want to do to change ur box |
|
Gold Member Username: B3n07Louisville, Ky USA Post Number: 1052 Registered: Jul-07 | i mean everyone agrees these L7s should be able to break a 140 right i just cant seem to get them to do it |
|
Gold Member Username: Hittin1TEAM REVOLUTIONLake Charles... Post Number: 3211 Registered: May-07 | i forgot, what amp are you using?. . And if the amp would fully power 1- L7 with the box built to optimal SPL specs I am sure that alone would break 140. Problem is you are using subs that thrive on larger enclosures and having to use minimal specs. due to space available. is this a trunk car? how is port and subs facing in vehicle? any pics of install? You could also try adding polyfill and see if that helps at all. |

Bronze Member Username: Michaelb1100Louisiana Post Number: 11 Registered: Apr-09 | I built mine, took me about 2-3 hrs because I had to have my uncle cut the layout, I went with the kicker 3.25cf spec tuned to 37hz on a Hifonics BXI1208d. It sounds great the only problem I have is the sub is a dual 4 ohm and the amp will do 1ohm so I am not getting the full power out of the amp. The box hits hard, out slams my sons 2 Memphis 10's. |
|
Gold Member Username: B3n07Louisville, Ky USA Post Number: 1054 Registered: Jul-07 | im using a hifonics Brutus 1600 one of the older models. i mean i could make the box longer but not taller ill post pics later to show you all what i mean. The subs are faceing forwards along with the port |

Platinum Member Username: Rovin1 15 = 149.5 DBs ...Trinidad & T... Post Number: 14962 Registered: Jul-05 | something has got to be wrong since like mark said 1 of those subs alone can do 140 with ease recheck ur install ... |
|
Gold Member Username: B3n07Louisville, Ky USA Post Number: 1056 Registered: Jul-07 | ill post a pic. could it be possible that the place i bought the subs sold me a sub with the L5 motor but the L7 cone? |
|
Gold Member Username: Hittin1TEAM REVOLUTIONLake Charles... Post Number: 3221 Registered: May-07 | possible..... meh likely... not so much I was hittin 142+ with L5's the 1600 watt brutus is overrated and is not really enough for 2 L7's. They could handle more. need more space for a bigger enclosure. Where are you getting metered at? what mic is being used? |
|
Gold Member Username: B3n07Louisville, Ky USA Post Number: 1057 Registered: Jul-07 | im not sure what mic they are using i know the program is all tl an its all being metered at the headrest. how much underrated we talking. could it be possible that the tracks im using are losing there bass when there getting burnt |
|
Gold Member Username: Hittin1TEAM REVOLUTIONLake Charles... Post Number: 3222 Registered: May-07 | what the.... you are only getting 137 dB's at the headrest.. You definatly have a problem(s). Try facing the port towards the rear. If you can, try to get metered with the mic in the kick or on the dash.. That is the norm and how I would know to compare scores. |
|
Gold Member Username: Hittin1TEAM REVOLUTIONLake Charles... Post Number: 3223 Registered: May-07 | also try the box toward the readof your trunk leaving a bigger space between the seats and enclosure (after facing the port towards the rear). and if you can make a vid (along with the pics) of the subs hittin and link us to em, would like to see how the amp is pushin' em. Did you do a sweep or try any different freq's when testing with the TL? |

Gold Member Username: B3n07Louisville, Ky USA Post Number: 1058 Registered: Jul-07 | we just used music because i compete in amature i can make a video but it wont be good because all i have is my phone |
|
Gold Member Username: B3n07Louisville, Ky USA Post Number: 1060 Registered: Jul-07 |   here is two pics from the front and one from the trunk ill try to get a video up im not sure where i will host it |
|
Gold Member Username: Hittin1TEAM REVOLUTIONLake Charles... Post Number: 3227 Registered: May-07 | youtube or photobucket work well. i was just wanting to see the excursion if the camera can capture it. did you try turning the box around... That is the norm for trunk cars. Usually it is noticeably louder. |
|
Gold Member Username: B3n07Louisville, Ky USA Post Number: 1061 Registered: Jul-07 | i did try to reverse them i think its louder facing forwards. when facing backwards i hits the trunk lid alot harder |

Gold Member Username: B3n07Louisville, Ky USA Post Number: 1062 Registered: Jul-07 | im going to host the video on my sprint account i wish some of you all lived by me or was going to some of the meca shows then you could see it in person. heres the video it shows i little bit of excursion http://pictures.sprintpcs.com/share.do?invite=XEQrmy2lh87T4k87h04x&shareName=MMS &messageState=RETRIEVED |
