You just have to play them for awhile maybe a week or two before they break
in. When new, the suspension is fairl stiff yet. Doesn't really matter how hard you play them, just not too hard at first. LK "Marcus" wrote in message om... How should I break in new subs?

They "break in" within seconds. To the original poster: this subject has been discussed ad nauseum in this group and in rec.audio.tech, among others. A simple google groups search will tell you all you need to know about the topic. There seem to be two groups making the arguments on both sides: those that read something from a marketing department suggesting to "break speakers in", and those that have performed the actual experiments or otherwise know how speakers work. |

you break in subs by playing them.
so why not just play them and dont worry about breaking them in..?? Marcus wrote: How should I break in new subs? I have only purchased used subs in the past so I have no idea which policy is best...Please answer and TIA... |

after you break them in and the suspension is JUST RIGHT, then
you better not play them anymore... You dont want to over do the break in... Levi Kudrna wrote: You just have to play them for awhile maybe a week or two before they break in.

i dont know why people can't understand that subs break in, you do not have
to break them in. Just play the damn things. |

It's true that break-in for woofers (any moving coil driver) is not required
but you should be aware of a high-end audio suggested break-in technique that can be very dangerous. This suggests placing a pair of speakers (usually meaning multiway loudspeaker systems with cabinets) face-to-face with out of polarity wiring and driving them with a noise or other high-level signal for overnight or even days. The idea is that with the speakers out-of-polarity the drivers will be 'exercised' but much of the sound will cancel. This is not only not necessary but quite dangerous. It's easy to lose track of how much and how long power is being delivered, how the voice coil will get and how easy it is to melt the glue or otherwise damage the driver. Most suggested 'break-in' techniques can easily be turned into ways that break-in your speakers too much.

Just to add something... Eric Stevens, technician for Image Dynamics has
stated that after one to two weeks of usage, the resonant frequency of a sub (an ID sub at least) can drop by as much as 20 to 25%, making the sub sound less boomy. From my experience, I wasn't extremely happy with my IDQ12s until about two weeks after installing them. Just my experience...

Two weeks is typical. |

Two weeks is typical. I was following a similar thread in rec.audio.high-end. One of the posters had always believed in "breaking in" new speakers, and always noticed a significant difference after a month of playing his new speakers. Then one day, he bought a pair of speakers that had been used for in-store demonstrations, and already had several hundred hours of playing time on them. Sure enough, after he had them in his house for a month, they sounded "different" to him, just like all of the brand-new speakers had in the past. That was when he finally realized that it wasn't the speakers that were "breaking in" - it was his ears. Scott Gardner |

Speaker SALESMAN always tell you that! If you are not sure how great your new speakers sound, it is a way the salesman can have you LIVE WITH IT for a couple of weeks before complaining about the new speakers.... BY THEN, you will have probably a) gotten used to them b) forgotten how your old speakers sounded in comparison (humans cant remember sound differences very long) Some speaker folks actually believe the speakers loosen up, but if they loosen up 25% in two weeks, then it stands to reason they might loosen up another 25% at the end of 4 weeks, and eventually be so loose they wont work anymore... ;-) I would like for someone to post some FS readings on a woofer and then play it a couple weeks and then post the FS reasings again and report on the difference.... no one has done this because there is no significant difference.. From my experience, I wasn't extremely happy with my IDQ12s until about two weeks after installing them. You got used to them! its a wonderfull salesmans tool to tell you to live with it a couple of weeks..;-) SUCKER! Eddie Runner http://www.installer.com/tech |

I asked around a little bit about speaker break-in after installing the Dyns in
my car. Dynaudio seems to feel that the speakers need 100 hours of use before they've "broken in" and started sounding right. But I've got to call bull**** on that one and cite Scott Gardner's posting about the guy buying the demo speakers and realizing that the break-in period is all b.s. The speakers do sound slightly different to me today than they did at the beginning of February when I had them installed, but that's probably due to the facts that: 1. I'm more used to them now 2. I made gain adjustements at the amp 3. I went back to the shop that installed them and we re-EQ'd the system. The Klipsch speakers in my room sound slightly different now than when I bought them, but that's probably because my ear has gotten more used to the slightly bright "Klipschorn" tweeters they use. |

I'm not entirely sure you can necessarily fault manufacturers for this suggestion. Obviously they can't put in their manual: "If you don't like our speakers at first, wait a while. Your ears will adjust. It's really the difference in sound compared to what you're used to that may be the culprit, rather than distaste for the tonal quality of the speakers themselves." Can you imagine the backlash? People would think it's just an excuse. They would proclaim: "This company is nuts! I have perfect control over my likes and dislikes. After all, I'm an audiophile!" |

I'm not entirely sure you can necessarily fault manufacturers for this
suggestion. I agree with you. I just think it's silly that this type of disclaimer is neccesary just so people will stick out the adjustment period. |

I've done the experiments on break-in. At the behest of manufacturers who
claimed that their drivers needed "break-in" I performed 3 different experiments (one of the was Dynaudio) using the recommended break-in techniques. But I also either demanded that the manufacturer supply 4 samples (so I could break-in "some" of them) or that they supply me with already broken-in samples AND fresh samples. Tom, I'd love to see your data if it's available. I'm not questioning your claims. Rather, I want to further back mine up. Here's the deal: when you measure a woofer immediately following break-in (when the voice coil is still hot) you'll find that the free air resonance (Fs) will be 5-10% lower but the compliance (Vas) will be correspondingly higher. How much of this is due to the supposed suspension change (ie break-in) and how much is due to an increase in DCR? |

Let's say 100 hours or so. I know near nothing about such testing but I'm still confident that such a change does not occur. |

Based on what I know (which is admittedly very little), I just can't see how anything of value to sound reproduction could change about a speaker after a "break-in" period. Of course, this assumes that the speakers are used properly. Damaging the speaker will obviously cause a change in sound quality. |

I think I have some brand new 12s in the store today I will measure the FS of both of them, they are probably nearly the same, and then I will hook one up in our display board which plays 24/7 and play it for a week, 168 hours a week.... then I will measure the FS of the woofer thats been played and compare it again to the one that has not been played..... I can measure this on my LMS computer, and post the results on my web site... Eddie Runner http://www.installer.com/tech |

You're right. The way I see it either: A. The break-in period does nothing to change the speaker's characteristics (as far as audible differences are concerned) or B. The speaker will *continue* to change after break-in, eliminating the chance of getting consistant sound over a long (2+ years) run of usage. |

Look for old issues of CSR. This was published.
I'm not doubting you personally Tom. I'm doubting the claims of manufacturers who say that a break-in period (100 hours in the case of my Dynaudios) will alter the physical characteristics of a speaker enough to cause an audible change in character. If this were the case, as Eddie pointed out, then the sound of your speakers should constantly be changing, because the speakers will never stop "breaking in", anything that happens in the initial 100 should continue happening thereafter. The only other option I can see, as per my earlier post, is that character changes of a physical nature and of a degree great enough to create differences audible to the human ear simply do not occur in speakers - at least not in *all* speakers. |

In some magazines I see your articles that say moving a woofer box around in a car wont change the bass ressponse, and we all know IT DOES.... http://www.installer.com/tech/aiming.html In other magazines we see Richard Clark telling folks he was the first to ever use a big capacitor in a competition car, and we know that Wayne Harris competed 8 years before RC did with caps...And others did also (I am using Wayne because it is a documented fact and I was there when he did).... I had a customer come in my store with an article that claimed a stereo system in a TRANS AM had 15 miles of speaker wire and the installers used 50 Lbs of solder to do the job!! Think about this for a minute, 15 miles of wire from front to back the the car would make a bundle about 2ft diameter, ha ha ha NO WAY and 50 Lbs of solder??? Solder usually comes in 1 Lbs rolls, ONE will last me for months if not longer...!!! 50 rolls on one car..?? I dont think so.... LIES LIES LIES... 1) the magazines need articles so they sometimes take ANYTHING to make their deadline. 2) the magazines manytimes wanna just please their advertisers so they do articles that are BIASED 3) many of the writers are MORONS, even when they interview ME about FACTS I KNOW they usuallys still write the articles WRONG!! I know alot of folks read these bull**** magazines and think everything in them is GOSPEL!
