Bottoming out 15"
|
Silver Member Username: SomedonniedudePost Number: 224 Registered: May-07 | I have a big problem with distortion. I have a 15" diamond D6 in a sealed 2.25cu box(roughly) running off a rockford p6002 amp. This sub bottoms out and isnt very responsive and sounds like @ss. its only running off of 1 channel on the amp too. (new amp should be here any day). At first I thought it was my amp distorting it, but it looks like its reaching full excursion off only 300rms (subs 750rms). It gets more responsive once as i crank it, but it still sound like its bottoming out. is this my amp or my box? Im gonna wait till my zx750s in before i do anything else. If its still bottoming out when i get my new amp, do you think polyfill will help this, or just need a new box? |

Silver Member Username: SomedonniedudePost Number: 226 Registered: May-07 | Its sealed. Polo what are you getting at? Is that sub better in a ported box? Man i hope i can get 1 ported that will fit in my trunk. |

Silver Member Username: SomedonniedudePost Number: 229 Registered: May-07 | Is there any specific way this must be set in a box, or does it matter? How much do I need? We have an old recliner were throwing away so I was thinking about cuting it open and seeing if that would work lol. |

Silver Member Username: TejcurrentPost Number: 509 Registered: Apr-07 | Just buy new stuff at walmart. Polyfill- ask someone in the arts/crafts section for it or 'pillow stuffing', same thing. |

Silver Member Username: SomedonniedudePost Number: 233 Registered: May-07 | Can this hurt my sub in any way? I got bored and pulled this stuff out of a recliner and it looks allot like it. I figured id give this a try, and if it works, sweet. If it doesent, then ill buy the better stuff. I dont make much money, so dough I can save is worth the effort. |

Gold Member Username: JohnfiacA-ToWn, 9515 thumpin... What u bumpin? Post Number: 3526 Registered: Mar-06 | I can only think of a few things..... Box is to big, subsonic filter isnt set and the subs trying to hit some lows it cant handle, or simply to much power for the box designed and by polo saying "sealed" that means it doesnt really have a tuning... ported boxs have tuning. THe sub would probally do alot better ported |

Silver Member Username: SomedonniedudePost Number: 234 Registered: May-07 | I think its my amp. The box is the recomended size from diamond. My amp doesent have an adjustable subsonic filt. The subs not fluttering, like its free air or anything, and it somewhat hits even, except for the deep lows(not broke in yet). Im only giving it 300wrms. If its still bad after all of this, im just gonna build a box. Theres a first time for everything  |

Gold Member Username: InsearchofbassPost Number: 6457 Registered: Jun-04 | I missed that you said sealed.....over stuff it....that will make the box appear smaller to the sub and see how that works |

Silver Member Username: B3n07Louisville, Ky USA Post Number: 312 Registered: Jul-07 | i thought puting fiberfill in the box made the sub think it was bigger not smaller??? |
|
Bronze Member Username: SqhoeHuntington, IN USA Post Number: 41 Registered: Mar-07 | port it. Mine did the same thing sealed because I wanted to drive it harder to get the output I wanted. Those things are pretty loud when ported. |

I never did it so im not completly sure but thats what ive heard on this forum. Ported is always going to make any sub louder sealed is ussualy used to retain the SQ with less output. |

Silver Member Username: SomedonniedudePost Number: 236 Registered: May-07 | could i pack it full of fill and throw an aero port in it? Well anyways i just got home from school and my zx750 has arrived. So ill see what happens when im done. |

Gold Member Username: InsearchofbassPost Number: 6476 Registered: Jun-04 | "i thought puting fiberfill in the box made the sub think it was bigger not smaller???" yes but only if you dont use too much after that it makes the box appear smaller to the sub |

Silver Member Username: SomedonniedudePost Number: 237 Registered: May-07 | ok. so it sounds alot better and actually gets somewhat loud now. Sounds good except for in the deep notes. It hits deep notes the hardest, but its reaching full excursion and bottoming out. I know its not broke in yet, so should i still go on with fill or wait till its broke in? I gotta go to work now so ill mess with it more tomarrow. Thanks for all the help. |
