torn spiders?

[req 5,000+ posts]

ok i'll try this again, correct me if i am wrong... with a 4V pre-out and volume set to 50% in order for that amp to push 1000w at that precise level gain would have to be set to 2v... by setting the gain to 3v. he gave himself 1/3 below that power.... so at 50% volume he should be at 666 watts.... trust me i was in the car when he blew the fac. tweets they went before he got half way up, his mids couldn't take much more

again, none of this is backed up by numbers that have been measured.

until you do that, there is nothing we can help you with. sorry man. we can just make suggestions.

That's not always true. I clip the hell out of my amp but my sub can handle the extra power just fine. It stays within thermal and mechanical limits so there is no damage. The amp does heat up if I run it full tilt with some heavy bass after about 45 minutes or so.
Subs blow from being overdriven. Whether that means the coils burned up or you pushed it beyond it's mechanical limits. The enclosure will also have an effect on these limits. As long as you keep the limits of the speaker contained, the type of signal makes no difference -- whether it's square or a perfect sine wave.

I think I LOL @ cotjones

you did actually mention the cause of mechanical failure but its hard to pay attention to when you follow it up with an insult that leads to the thread becomeing a trainreck needlessly

what other numbers do you need?

the pre-out is rated to be at 4.V...given

it is fairly easy to tell when you are at 50% volume... given

the input voltage settings that the amp is rated at are printed on the gain control knob.... pretty much given... what needs to be meausured?

 

[cotjones 10+ year member]

oh and something else..... if that shitty amp can put out 1500 watts then why was i called such an idiot for saying that a 1000/1 could put out 1600... when you all know full-well that they are among the most conservatively rated amps on the market?

no explanation for this huh?

 

[Warbleed 10+ year member]

yea after all not even 3/4 isnt even cranked all the way..
have any idea on what the gain even does?

U R LIAR GAIN IS VOLUME KNOB! //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

thats not true eaither.

go measure it.

unless you give me ACTUAL numbers, not something you are guessing on, it has no basis in reality man.

because a volume knob could go up exponentionally and not be even across its entire bandwitdth. dont forget about bassboost, crossover points, lowpass filters, eq ect.

unless you MEASURE IT WITH A METER, "50% volume" means nothing but speculation.

not even to say they "werent" over the 1000w limit... they still could have been getting more wattage than recommended at the 1.5 cubic foot enclosure size. this seems kinda fishy, but its the only suggestion that makes any sense beside manufacture defect, but again - ive never heard of a type x spider ripping.

Do you understand clipping?

Didn't think so.

Read up on clipping and how it affects average power output, should answer your question.

I'll give you a hint;

For a sine wave, Vrms = Vpeak*.707

For a square (clipped) wave, Vrms = Vpeak

when you all know full-well that they are among the most conservatively rated amps on the market?

They are not among the most conservatively rated on the market.

And I'm not saying that as an insult. I think it's a little ridiculous the amount of intentional underrating some companies do....such as the RF Power series. There is nothing wrong with an amplifier outputting only ~10-20% over it's rated power.

But it's just flat-out nonsense to think that JL is some of the most underrated amps on the market.

With regards to the original poster, as has been said time and time again, your friend tore the spiders because he didn't know what he was doing. It was most likely a combination of grossly excessive gain settings (it's used to match input voltage, not as a volume knob), bass boost, and quite honestly, deaf ears. You'd have to grossly overdrive those speakers to tear a spider, and there's no way that could've sounded good, unless you are so used to listening to distortion that it didn't seem out of the ordinary. Speakers under heavy mechanical stress tend to object rather strongly to it.

Big boxes don't tear spiders. Clipping doesn't tear spiders. Overdriving the speaker past its mechanical limits repeatedly, however, does in fact tear spiders.

As I said in the beginning, he tore the spider because he didn't know what he was doing.

Your personality, not my comment, caused this thread (and all the others) to turn into a trainwreck //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

This thread boggles the mind.

well.

i tried to give logical explinations and not be an ***.

*shrug*

guess thats it. thanks squeak and warman //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
