Running in a sub? do you?

[Dansta]

do u?/how do u?
and what benefits could u see?

 

[Dink]

best way to run it in is give it full power from the start

it's is only that the sound changes ever so slightly after running in

it is capable of full tilt strait out of the box

 

[The Fatty]

^^^ wrong is i might add...

the reason to run in a sub is to get the coils warm, and take there final shape. this can affect the resitance/wattage and cariteristics of the speaker.

its best to run in speakers on half power for 10 hours straight, then let the cool for half hour or so, then you can give them max power.

it is true you can use them straight out of the box, but speaker thats been run in sounds better imo.

 

[Dink]

the amount of varnish they put on the coils it aint ever going to deform with giving it full power

running in just loosens up the suspention so it will move a little easier after it is run in

 

[The Fatty]

um no it dosnt, you wont loosen a rubber suspension but moving it a bit...not the stuff they use anyway.

 

[Dink]

no i was talking about the spider

 

[White16valver]

I noticed that mine was really tight for ages until I whacked full power through it for about 15 minutes - now it seems 'looser' and drops better

 

[The Fatty]

i cant be bothered to have a cat fight, but this has been discussed many time b4... a post from another forum for example:>

"It goes for spl especially!, I helped build a couple spl sound competition systems, for meca, and various other spl competitions. If you don't break in your sub woofer before you put 3000watts to it, its over. Buy another speaker. The main one i broke in called a kicker solobaric L712 i let it sit free air, and play at 18hz for 24 hours with 100watts, the amplifier i put the speaker on had 1800 watts and the speaker was rated at 700 rms, and 1500 peak watts i beleive. Now the reason i could crank that speaker up and never blow it, is because like brent said, it was flexible and it sounded a lot better afterward. What'll slowly tend to happen if you don't break it in, is the voice coils will slowly heat up, causing distortion, and suddenly, (especially if you run ported box) your voice coil will start smoking. That speaker had a protector coat so that before the voice coil started really getting messed up you'd smell funk. But not all speakers have that, and once the voice coil heats up past it's limit, it's Flame on! So break it in!"

that was taken from the first site that came up in google > http://www.sr20forum.com/archive/index.php/t-107093.html

lol wtf are they on about

the coil has a positive tempreature co-effiency so the hotter it gets the hight the resistance thus less power going through it so less heat.

it levels off with it's max power so it won't break distort whatever.

and i sound like to me he played a pure tone through a sub in a ported box that was below the boxes tuning freq thus ending in one dead sub

 

[The Fatty]

according to your theory speakers wouldnt burn up then?! hahahahaha

 

[Dink]

did you not read this part

and yes a sub will die if you drive the amp running it in to clipping, put too much power into it. playing a freq that is below the boxes tuning freq(ported boxes only).

 

[The Fatty]

dink im not sure if you've noticed but were the only 2 posting in 2 threads. lol. so im gonna stop posting in this one for now, with my opinion of, yes run in your speaker, it dosnt take much and can only aid you in the long run.

 

[bmh.01]

I just used mine as I normally would from day 1, didn't cane it and wasn't soft on it either. Never seemed to do any damage, sound did improve over time.

DLS are pretty much gurus of speakers with thier IR range winning most of teh gold medals with EMMA.

They said and I quote "run the sub in gently for 20 hours only after then will it sound as it should"

nuf said i think

pretty much what I did when I had mine in, sounds much better after running it in!

 

[Dink]

but what would it sound like if you didn't???

i'd guess exactly the same tbh

 

[wozzaa]

My RE sub souunded better after a few hours. But i drove it fairly hard from the day it was put in. Just seems more responsive now and drops a bit lower than when i first got it. But i doubt breaking it in slowly would honestly make much of a difference.

 

[muz]

would you take a brand new engine and thrash it from cold?

 

[Dink]

completely different tbh

you don't need it to warm up anything to be better protected

 

[The Fatty]

no but you do need to brake it in...else damage to the coils is possible. and i think he was talking about an engine from new, not cold.

 

[Dink]

i still can't see how you are going to break the voice coil.

the only way to damage it phyisically it to get the coil to hit the back plate or get it to come out of the coil gap.

if that happens it is fuberd but that will only happen if you put massive amounts of power into it

 

[jamesy]

you will destroy a speakers voice coil by supplying the coil with a degree of power which generates a degree heat of which the coil former cannot dissipate therefore the bond which holds the coil to the former will melt rendering the speaker useless this is easily detected by pushing the diaphram in slightly and evenly from two sides also by simply smelling the spider however its a known fact the more speakers are destroyed from distorsion rather then thermally from overpowerment

back to the original question yes you do need to wear a sub in and on average takes about two weeks THE FATTY seems to have the right idea.

yeah distortion = clipping whick will kill a sub as it means the amp output could be nearly double so over powering it

so there is still no proof that running a sub at full power out of the box is going to kill it

 

[jamesy]

actually the main risk of amplifier clipping is that clipped signals contain excess high frequencies which can destroy drivers with small voice coils

 

[Dink]

no clipping is over driving the amp past it maximum output voltage so the amps output transistors are on longer because the signal multiplier thus creating a flat top to the waveform

 

[jamesy]

i know what amplifier clipping is and what i previously described is one of numerous results of it i do this stuff all day long for a living my friend i dont need to be dictated to

 

[The Fatty]

well said jamesy, you have a much better way with words than i do, but on both points thats exsactly what i was trying to get across! thanks!
