Running in a sub? do you?

^^^ 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.

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 
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!"

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

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