this is sort of a stupid question i think, but is there a break in time on subwoofers?

Its all depending on the sub manufacturer, a couple lines i'm familiar with require a 2-hour of constant playing time to break them in. But this is only for the mid-range subs...comp sub require a bit longer of playing time...Now, it says require but this is only to achieve maximum potential of the speaker.

Going to throw in my $0.02.

What ever "breaking in" is done to the speaker/driver has a far LESS effect on the sound as does the breaking in of your ear to the new speaker.

By this I mean that over time you become accustomed to the sound of a particular speaker.

This effect if much greater then what *might* accure by "breaking in" a driver.

Ok.  Lets say that breaking a driver in does really have an affect.  Where are the white papers?  Oh wait, not white papers, those are theoretical.  Where is the PROOF? 

You should be able to test a speaker's compliance before and after break in.  Test its frequency response...etc...

This is a matter that can be put to rest for EVER if some proof is provided.

Here's the bottom line:  No speaker "requires" break-in to prevent some sort of damage.  All speakers potentially operate better and can sound better after they are "broken-in."  Period.  The proof is in the ears of the listener and the effect is different for every speaker.  Every speaker is different and reacts to operation differently.  The most common effect of break-in is a lowered fs.  Some manufacturers recommend a break-in period because their experience shows that their speakers sound better if it is done.  Others don't.  Simple.

Ok, In all my years of Installing , I have never heard of a break in period... customer comes to me and states, I want my car to hit  like this or pound like that... I show him several options... I install the speakers highs lows mid range subs or what not. what ever he/she is here for.. Then having all my wires run I install the amps... then I tune all the amps for peak output with max radio volumn.. with out speaker distortion, popping, or engine feedbacks making sure max grounds set for stereo and amps... number one problem is after something is installed , people must see what all these dials on radios and amps do.. So what do they do.. hmmm wonder why this gain is not turned all the way up, wow it says my amp is 1/2 ohm stable, why isnt my amp bridged not even concidering what ohm rating the subs are or the configuration is setup for.... Then the phone call, I smelt something burning , and my amp is cutting out or clipping, no I notice my amps is running very hot.... or my one speaker is popping or resonating without and sound just jumps up and down in the speaker basket.... there are certain instances where certain subs will perform well above expectations, few companies out there have an affordable line that does so.. so Dont confuse 1000a max with rms.. know your speaker and or systems limits and If you want stuff to last run it within its limits, dont need to set world records unless you can afford it!!!!

Welcome to the forum.  You should learn quite a few more things here, as well.  Breaking in subs - Page 3 -- posted image.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I havent followed this posted subject for some time...purposely.  Im confused why its still rolling, being as ____as it is.  Of all things to pay attention to...that actually mean something...for what little the results give, why a break in period is of anyone's concern?!  I even gave it a benefit of the doubt....wasted money on a speaker someone mentioned earlier in this post since the instructions make an alleged statement of break-in (ill give thanks for the refering person, by the way)...after hours in the lab, I used a spectrum analyser among other equipment required inside our dB chamber while abiding the rules of the speaker's literature.  When I was talked into being neutral to the "break-in" method, I though."Im going to tackle this so Ill personally be satisfied while leaving everyone else alone."  Well, I kinda got irritated at the results, gave the speaker to the first employee that crossed my path and told them to leave me be.  I hope someone with lab access other than someone involved with a manufacturer or affiliate will takle this other than me.  If you do....No, nevermind, dont involve me.

A car, motorcycle?  SURE, break it in because theres binding / moving metallic parts that actually require lubrication via oil pressure and such that is filtered during the process....therefore it actually has a reasonable break-in process to follow.

A speaker should NOT have frictional drag of any part other than the material resistivity of the surround and VC mesh.  At least you hope your speaker doesnt, if so, return it!

Im going to ignore this post for as long as I can...again...and come back later to see how long a dead horse can be beaten........

Peace....I guess
