Voice coil short
|
Silver Member Username: BelieveIllinois Post Number: 112 Registered: Jun-05 | i had a short in my old school infinity sub when i took it apart i noticed on the bottom of the coil there was lots of abrasion.. soo much infact that it started to break the copper strands.. they didnt unwind or nothin.. they just dont make a complete wire anymore so why does my coil have a small patch of abrasion? my guess is because i was pushing the motor past its linear limits and once the coil went past its xmax it started to wiggle i think some ferrofluid in/on my coil would have lubed it up good so that wouldnt have happened maybe its a good idea to add ferrofluid to lube the coil so your subs last the abuse what do you think? |

Silver Member Username: BelieveIllinois Post Number: 119 Registered: Jun-05 | well your wrong when your pushin the coil to the point where it almost pops out.. you best have some ferrofluid in there to keep the coil from rubbin away like mine did i cant see why your reply with this rubbish anyway yes i know how a speaker works.. and i also know its simple logic that anything that moves creates friction.. friction creates wear and heat if you take a razer and cut a couple spindles that wrap around the voice coil.. it wont work anymore same thing applys when you give the side excessive abrasion until the first layer of wrap is rubbed away.. which causes the coil to short speakers dont move in a magnet totally linear.. especially when you are pumping the speaker hard its a little extra performance with less worry |

Gold Member Username: RovinTrinidad & T... Post Number: 8036 Registered: Jul-05 | thanx ! ^^^^ http://en.wikipedia.org/wiki/Ferrofluid i would think if ferro fluid was necessary in that sub the manufacturer would have themselves put it in during the manufacturing process so y even bother thinking about it ... |

Silver Member Username: Van_manBoston, MA Post Number: 449 Registered: Mar-06 | Hey believe, I can help you, I just made a fresh batch of fluid from some old vhs tapes. Ill let you buy some for your subs. $148.57 per fluid oz. let me know where to send it. |

Silver Member Username: BelieveIllinois Post Number: 120 Registered: Jun-05 | brandon: the word linear - a straight line shaine: your 16.. and i am just rovin: the manufacturer doesnt recommend pushin the sub past its linear limits.. i did and found abrasion that could of been lathered to prevent further distruction marc: your a reject anybody else wanna argue fact? |

Silver Member Username: Terry6405Sullivan, IN US Post Number: 814 Registered: Sep-05 | if a manufacturer thinks that it would help, they would do it, because they know people will push there subs and they want to make durable product, usually anyway. Im sure your not the first to think of lubrcating the moving parts on a sub, yet, oddly, none of the companies do, so ill bet someones tried it and seen that its better without. Besides, i wouldnt want to lube anything with a current anyways for the sake of a short. dont ask for help and then put peoples opinions down when you get it and based on your last post, ill bet that youll have some smartass little comment for me soon. Don't bother, i wont waste any more time by reading it |

Gold Member Username: B101Queen City, NC USA Post Number: 3076 Registered: Sep-05 | The fluid would help, to be honest..  I think its a matter of cost to the manufacturers... It can be a good sheild to protect from extra heat to the coils... HEAT KILS "They are used in loudspeakers to sink heat between the voice coil and the magnet assembly, and to passively damp the movement of the cone. They reside in what would normally be the air gap around the voice coil, held in place by the speaker's magnet." If u did your own recone, and had access to some, then it would be a good idea. |

Silver Member Username: BelieveIllinois Post Number: 123 Registered: Jun-05 | terry: i didnt ask for help! if you took a wholesale lot of real old cerwin vegas from the 90's.. i bet most of them had ferrofluid in the coils added by their car show enthusiastic owners i got a pair of mtx subs that have seen massive use.. they got ferrofluid in them those speakers are 14 years old! and for the most common use of ferrofluid.. that would be what b stated above.. to get rid of the heat... thats safe.. and safe is totally recommended ;p i guess i should be thankful i didnt tear a surround or pop the coil out |

Silver Member Username: LexuscoopPheonix, Arizona USA Post Number: 479 Registered: May-06 | um believe im 17 not 16... THE WHOLE POINT IS YOU DONT' NEED LUBE ON THE VC! you don't need to diss everyone that said something on this thread, your the reject along with Brandon |

Hey Believe, change your user name to question, cause you dont believe anything. Hey I have a question Believe" Does sh!t stink?",stuff some up your nose and tell us the anwser.LOL |

Silver Member Username: BelieveIllinois Post Number: 125 Registered: Jun-05 | well if half of you are gonna act like high school bail bond rats.. curfew is up soon i asked what yall thought.. im not dissin people im dissin thoughts shaine: tell that to my other identical model sub that sees the same abuse the first thing i said in this thread 'in short' my subwoofers voice coil was rubbin the side and it ruined it.. if i woulda put some ferrofluid in before it got ruined it wouldnt have happened and here comes a long train runnin of ppl tellin me that the facts are wrong i think we need to start a ')dont believe them for sh!t(' board some of yall got checks lol _________________________________________________ im not sayin yall suck cause your scared to take your sub apart to put some ferrofluid in it i dont suggest you do that at all if you take it apart and cant put it back together your sub needs to be repaired by someone else.. that means your gonna have to drive with no sub for a day cant have that because dustcaps nowadays are so funky to take off.. dont test it on a cheap woofer and try it on an expensive woofer your results wont be the same i will say.. small dustcaps are easier then big dustcaps that take up the whole cone removing the dustcap is all you have to do when applying ferrofluid |

Silver Member Username: Terry6405Sullivan, IN US Post Number: 816 Registered: Sep-05 | i knew i said i wouldnt be back but i stumbled on to this and i couldnt help it "so why does my coil have a small patch of abrasion?" "what do you think?? those look like questions to me, questions seeking answers..... ansering questions is help. lol. moron. |
|
Silver Member Username: LexuscoopPheonix, Arizona USA Post Number: 515 Registered: May-06 | ^^ agreed, if you are so all knowing why ask for advice? do this on your own if yoru going to say we are wrong because your subs suck and couldn't handle the watts you were given them, its yoru subs fault not the lak of lube |

you are delaying the inevitable. if the VC is rubbing....then the motor is not aligned right...and will need to be fixed. Lubing the parts that are rubbing, that shouldn't be rubbing is only a temp solution. |

Silver Member Username: BelieveIllinois Post Number: 126 Registered: Jun-05 | terry: your english has no structure if i would wrote it like.. 'so why does my coil have a small patch of abrasion..?' that would imply sarcasm with the answer shortly below maxx: whats wrong with the 1999 era of subs? audioholic: im still human muddy waters: the abrasion is at the very bottom of the coil.. im almost certain it was trying to pop out (the surround probably wasnt long enough to allow it) could be an uneven surround too tj: hi |

Its not that we have a problem with debating on this fourm, but look back on your posts. You've talked sh*t to everyone and your answering people with a negitive attitude and snide remarks. It's best for you to reply with i think it could cause blah blah blah... well your wrong.. and i cant see why you reply with this rubbish anyway.... i see where your going with your points... but these points wouldnt be coming up if there wasnt a problem with your subwoofers in the first place... i agree with muddy... but since you say your VC had an abrassion at one certin point in the VC... you could have had your subwoofer in a poorly built box. you could have some clipping problems going on within your system.. your amp could be setup wrong, yada yada yada your VC wouldnt be compleatly exiting the Motor structure or tapping the bottom of the frame if the sub was not excurting in the first place |

Silver Member Username: Nnnnick_bWeddington, Nc Usa Post Number: 809 Registered: Jan-05 | The only place I have seen ferrofluids used is in tweeters and small midrange drivers. These drivers don't have/need alot of xmax. THus they can not cool them selves as effectively as a woofer with a vented pole piece. Also, the gap between the pole piece, the VC, and the Magnet is much smaller then what is seen in a woofer/subwoofer. This is where ferrofluids are designed to work. They transfer heat from the VC to the pole piece/magnet, and in some cases help dampen/align the VC. |

I shall retain proper gramtical writing style from here after... If I were you, i would't try to play the smart card untill you know who you are talking with. Besides, I don't have to prove that I am smart, my 4.0 college GPA does that for me, but nice try. |

Silver Member Username: Van_manBoston, MA Post Number: 465 Registered: Mar-06 | Hey believe, Im making another load of thermo fluid. Its a bit hard to get it out right now, but reading your posts inspires me. ahhh here it is, ready to slide into your subs. |
|
Silver Member Username: BelieveIllinois Post Number: 132 Registered: Jun-05 | that college gpa is only good for 2yrs after graduation nick: those 14 yr old subs dont have a vented pole piece other then a cloth dust cap.. so it was quite beneficial terry: teachers dont retain intelligence.. they just pour it on slower for ppl who dont comprehend as fast |
|
Silver Member Username: Terry6405Sullivan, IN US Post Number: 819 Registered: Sep-05 | yea, im still im college, and your right, teachers arent smart, especially not the doctors.....(sarcasm) may i ask, how old are you? where did you go to school? and where is your bases for trying to act smarter than i am? trying to compinsate something small with a big ego??? face it, your drowning, everything you say make everyone respect you even less. if i were you i would just quit now |
|
Silver Member Username: BelieveIllinois Post Number: 133 Registered: Jun-05 | what is your bases for thinking that i am trying to 'act' smarter then you? if you got an issue punk.. raise your hand and see who the teacher calls on first my egotistical @ss was often the one who was going from person to person teaching other students in class.. whether it was my firm grasp on the subject or my social skills.. i helped teach what i learnt respect means nothing to facts.. and thats what i started with jealousy is real.. if you would take the effort you make to disrespect me and apply it to your school work you would have a higher gpa to throw in my face |

Silver Member Username: WinterfreshpimpChisago, MN America Post Number: 384 Registered: Mar-06 | nothing is wrong with them, just if youd had it for so long you shouldnt be so surprised it died out on you and lube is just rediculous sounds to me like you got your moneys worth |
