Well it's more like breaking them in, most places I know of say never turn them up past half for the first few months. I know mine sounded louder after 3 months. My friend didn't do this, all he would do is drive around with up his up all the way, he blown a spider doing that. So maybe your breaking the spider in, or the voice coils.

Im not exactly sure on this, but i've been told about the breaking in and witnessed the blowing accident.

I think he's talking like a daily warm up, but true enough all speakers should be broken in (just don't wail on them as soon as they are installed.).

But daily, as long as the ambient temperature isn't freezing or too hot (sitting in sun all day). Then the surround and other parts could get damaged during high excursion events. No real rule, just use common sense.

3 months...ha



RE told me dont worry about break in on any of theirs, MT is one of the stiffest subs evar but playing the thing moves pretty good not like the XXX though

i still dont kill them the first day but 2nd day i let it rip

break in will happen with normal play over time the sub will sound louder and play deeper( to the ear, break in will usually hurt an spl score usually ive seen fresh subs hit higher deebeez)

I do that with my stock speakers...call me nuts.

If it's really cold, I'll listen to music really low, then slightly increase it as I "think" they would get warm...lol.

Ok, to break in a subwoofer starts when you get it in the mail!!!

First you need an amp of some sort, a dvd player with speaker outputs will do.

Start by playing a 10hz track

then move up to the 15hz track

then on to the 20hz track through the sub for at least 100hrs total.


then start running sweeps at low volume and start turning the volume up. This should probably be done when no one is around as it can get really loud.

Then you subwoofer should sound pretty darn amazing the first time you play it and will sound better with time as long as it doesn't sustain any damage.

very very true.

cold coils on a fresh sub is the best way to meter

i just fun a few test tones (about 3-5) mins on the sub...go back inside after installing...whatch some tv, catch up on the computer, eat...then go back outside and let her rip


a great warrior once said...it's a sub, not a vagina.

i have an issue on cold mornings(in SoCal that means 45) that the sub just keeps on making a popping sound until the radio starts giving it a signal. it's weird, but i have no idea if it is a problem

Or you hook it up and use a wave test on a Bass CD.

This sounds like a big of overkill but I guess it could work and a simple way to eliminate how loud it would be is to let it play "free air" without being mounted. If you did that it might vibrate a lot but the airwaves will cancel eachother out so it wont sound like much at all.


Also, if you want somethin in writing from a good company go to kicker's site and look up their manuals for L7s then click "tech info" and it will tell you how to break it in if you have the special ept. and if you dont it tells you to play it at "normal listening vol. for 1week".

most subs require about 10-15 hours of time at only about 3/4 of the watts it takes to power them for them to be broken in. it is always safe to go more than that but you dont need to.

Well, I build home speakers and when you pay a couple hundred dollars for a single speaker, you tend to want it to be broken in correctly.

With a regular speaker like a 3.5" Scan-Speak Revelator Midrange you would use different frequencies, of course.
