Silver Member Username: StnorrisEldridge, IA US Post Number: 122 Registered: Apr-06 | AGain for the 50th time, i have 2 12 Cvrs. dual ported box 38hz. 1.8 cubic feet per chamber. My subs sound like sh*it. They dont sound good at all. The sq is horrible when i turn it up loud. I think its not my box, its something is wrong. Can anyone name some possiblities that could affect my sq on my subs like this..... |

Gold Member Username: GoatinOhio U.S.A Post Number: 1127 Registered: Jan-06 | Thats because you have them setup for SPL. Build a smaller box ported @ ~35hz or less for more SQ. |

Silver Member Username: Thomas_gNM Post Number: 610 Registered: Oct-05 | uh duh. jk tune about 32hz or 33hz or 35hz. |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 125 Registered: Apr-06 | i dont know if its just cause the box is 38. they sound too bad even for that high. im not sure what im going to do. i know the kicker cvrs call for a ported box at least 1.75 cubic feet though. |

Silver Member Username: Thomas_gNM Post Number: 611 Registered: Oct-05 | yup i had my box tuned to like 40hz for a while and didnt like it so tuned it lower and i like it 500% more. |

Silver Member Username: Thomas_gNM Post Number: 621 Registered: Oct-05 | can you tune a box that low for a couple of cvr's? |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 127 Registered: Apr-06 | is there any way i can adjust my box, and make it better??? |

Silver Member Username: JohammbassCork, Cork Ireland Post Number: 188 Registered: May-06 | Next time use sealed Less pain, way more SQ |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 128 Registered: Apr-06 | what if im going for a low tuned ported...like a 32? |
|
Silver Member Username: JohammbassCork, Cork Ireland Post Number: 189 Registered: May-06 | I guess you could give it a shot, however, I like my bass nice and tight. Ported is more like if you wanted to run lower power and loud. If you go sealed, you have to give it plenty of power. Sealed is just so much easier, who cares about extra 3db if ported, not me |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 129 Registered: Apr-06 | extra 3db would mean twice as loud... what subs and amp are you running anyways?? |

Silver Member Username: JohammbassCork, Cork Ireland Post Number: 192 Registered: May-06 | Right now I am not running crap, but the last thing I ran was 1 x 10W6V2 (which is junk BTW), powered by Tantrum 500.2. The funny thing is - before then I ran a couple of cheap RF 12" SVC, I had paid $50 for both (Soundwaves sale), powered by the same Tantrum AND they sounded more accurate than the W6V2 no sh!t. People would get in my Integra and ask - man what kind of subs you got. Even when I showed it off to Soundwaves guys, they could not believe that those cheap RF's could sound like that. Yeah BTW, in general, I don't like RF. Yeah and for example, these subs right here will outperform W6V2 in SQ, like if it were made by Jensen http://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=3068 |

Gold Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 3036 Registered: Sep-04 | yeah i wouldnt say that statement.... as for his box making the cvrs sound bad. they should sound THAT bad anyways. it could be a problem before then. maybe clipping fomr the HU or the amp. if you put them in a sealed box and they still have a problem, its definetly somehting else, which i think may be the case. |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 131 Registered: Apr-06 | its not clipping. unless is was coming form my reallly shi*tty HU for some reason. The hu is kenwood 2V with barely ANY settings. its a pos, but now im getting this clarion which retails for $480 and its 4v.....and its also 10 times better than the HU i have now. but i did have the amp set to 2V ......... |

Silver Member Username: Thomas_gNM Post Number: 636 Registered: Oct-05 | Hey stevo its ur box man i know it is. |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 132 Registered: Apr-06 | what should i do? i bought the box for 100 dollars because i didnt want to go through the process of building one and making the port because it would be a hassle getting the tools and parts. so i bought this box hoping it would work. Anyways...how can i tune the box down to around 32hz (the box on the link)? got any good sites or instuctions? |
|
Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 735 Registered: Jan-06 | You would have to increase the port length inside, and that would be a sloppy fix. That box in the picture doesn't look very bad though, so I don't think it is the box, unless there are visual deformities or damage. Kickers will sound pretty bad even at their best though... But they do get loud. It is tuned to 38 Hz which is pretty high and will never sound very good, so you could try getting a new box. If it was me I would build a new one myself, or sell the subs with the box on ebay, and get some quality equipment. |

Silver Member Username: Thomas_gNM Post Number: 639 Registered: Oct-05 | http://www.subwoofertools.com/forum/ported-box.asp Is a very good site if ur gonna build one. |
|
Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 736 Registered: Jan-06 | Another thought, you said "sounds horrible when I turn it up loud", that is usually a problem with your electrical system or your amp. If you don't have enough power on tap to feed your amp, it will sound stressed and distorted as you increase the volume. If it sounds OK and increases in volume nice and smoothly up to a certain point, and then stops getting louder and starts sounding distorted, it is probably an indication of your amp not being powerful enough for that volume level, or your electrical system can't deliver enough to the amp. If it sounds bad at low volumes, then it is probably your box or some other factor than what I mentioned above. |
|
Silver Member Username: Thomas_gNM Post Number: 640 Registered: Oct-05 | If i was you id just sell that box, use the site i put on there and build one urself tuned to 32hz. |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 136 Registered: Apr-06 | Im not sure if its my box or subs. maybe its the fact that my cheapppp Kenwood HU sucks. or maybe that my trunk lid rattles reallly bad on the inside, or my fuse isnt big enough? i just got some edead sound deadner for my trunk. Im getting a WAYYYYY better HU in a few days. I only have a 60a Fuse, but i need an 80a. could any of these be at fault for BADD sq? |
|
Silver Member Username: Thomas_gNM Post Number: 644 Registered: Oct-05 | A SQ problem could be from ur HU but i think its just that you have ur box tuned to high if u want more SQ. How much is edead and where are u buying it from?? |
|
Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 742 Registered: Jan-06 | Your fuse is a 60 amp for a reason, do not put in a larger fuse. |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 140 Registered: Apr-06 | how would it be 60 for a reason. fuse holders and fuses didnt come with the amp! its 60 amp because i put one in too small, because i havent recieved my fuse and fuse holder yet through the mail. Trust me, the amp is 800 rms. i need at least an 80a |

Bronze Member Username: BelieveIllinois Post Number: 59 Registered: Jun-05 | if it hits low enough for you.. just stuff the box with polyfill if its not getting low enough.. stuff it with polyfill and turn the subs facing inside the box so the magnets are outside dont be cheap and use just one bag try two or three in each side if you cant get sound quality after trying all that.. you have a distortion problem |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 141 Registered: Apr-06 | tj, how did you tune your box from 40 (or whatever it was) down to 32, and 35? |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 142 Registered: Apr-06 | believe - would putting that in my box on both sides be similar to having the same box, just tuned lower than 38? when i bought the box, it seemed like it would work awesome. theres also the other factors i listed though.. |
|
Bronze Member Username: BelieveIllinois Post Number: 60 Registered: Jun-05 | if you put polyfill in and put the magnets inside it will play 4% deeper if you listen to it and it will sound a lot better as far as sq now if its still not low enough.. you have to put the magnets outside the box.. that is the same thing as retuning the box.. your putting more room in the box because the magnets are outside but if you put the magnets on the outside you need to put even more polyfill in.. im talkin double up on it.. that way you will keep the sound quality you got when you first added polyfill the two things to listen for are 1. it plays lower 2. the bass stops faster when a note is done kinda like less echo in the box |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 143 Registered: Apr-06 | ya i might try to get some that. should i go ebay or where to u suggest i get it from? |
|
Bronze Member Username: BelieveIllinois Post Number: 61 Registered: Jun-05 | whatever is cheap fabric store.. walmart no more then 3 bux a bag |
|
Bronze Member Username: BelieveIllinois Post Number: 62 Registered: Jun-05 | maybe you can find a big 10lb bag for under five bux? try to get a whole bunch in one bag for really cheap.. if you cant find a big bag then just go with the small bags |
|
Silver Member Username: Thomas_gNM Post Number: 645 Registered: Oct-05 | I first built that box on the kicker manual "the spl/deep bass series" enclosure the port was 3" wide and 20.5 long all i did was shrink the port side to like 1.75 inches wide and i forgot how long. I uses that site i posted above and its great. In a few minutes im gonna build 2 small sealed enclosures for my cvrs. |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 144 Registered: Apr-06 | believe - wont i also need to get some sort of grill over the ports, to keep the stuff in the box??? also, do u know if my fuse being a 60 instead of an 80 can be distorting my amp? my subs sound good at low volume too....... |
|
Silver Member Username: Thomas_gNM Post Number: 647 Registered: Oct-05 | Usually the poly doesnt come out of the box cuz your supposed to stuff it and it all holds together. |
|
Bronze Member Username: BelieveIllinois Post Number: 63 Registered: Jun-05 | you shouldnt need a grill for the port.. just dont put a bunch of pinches by the beginning of the port.. put nice big globs of fill in that area.. no small loose stuff that you can blow with your mouth if you wanna take some duct tape and make a circle.. double side some of the good size globs to the inside of the box so they cant blow out (take one side of tape and connect it to the other.. then just press it on) if that fuse doesnt blow at mid volume then its not too small the size of the fuse doesnt matter.. if you put a bigger fuse in the amp it will allow the amp to distort more! and then it will be broken with smoke coming out about an hour later |
|
Silver Member Username: StnorrisEldridge, IA US Post Number: 145 Registered: Apr-06 | i read that polyfill is only useful for smaller boxes, and you use it to compensate for it. cause it tricks your subs into thinking that they are in a bigger box......i dotn think my box is very small at all. |
|
Bronze Member Username: BelieveIllinois Post Number: 64 Registered: Jun-05 | they are tryin to teach you abc's it makes the subs play lower it reduces the stop time / echo in the box doesnt matter if your subwoofer is in a gun cabinet or a refridgerator its still gonna do that to it |
