[QUOTE="Buck, post: 8754484, member: 591582"] I got an official response from my guy at DD. He gives me t/s data on DD stuff, I get a more direct line of contact than you would just being a customer, I would say. So I genuinely asked his opinion about breaking in their woofers, how important it was, and I asked him to very honest with me. He was. He really stated that he thought breaking in subs was important. I have to paraphrase here, I tried to get a direct quote for you guys. Maybe I will soon. What I was told was something like this (this is paraphrased, not a direct quote): "Many spiders have [U][B][I]resin[/I][/B][/U] in them. Subs will drop Fs and improves motor force/Bl (t/s). Bl increases due to softer suspension. You really have to wang to break them in properly." He says it's vital, at least from a competition standpoint. I'm keeping this as simple as possible and trying not to say anything that I wasn't told. One of the biggest things that I picked up on was this: it's largely power-level dependent. A 500w sub maybe doesn't really need a break in time. It's 500w, there's probably nothing that's going to damage a sub that low powered. When you have something like a 2000w, 3000w+ woofer, then that's when break in becomes even more important. The amount of power that is in a 4" coiled woofer, for example, requires a massively stiff spider, relative to that 500w woofer (don't forget about added spider stress of larger and larger Mms's as power handling increases). It seems that how rapidly a spider expands or stretches from it's brand new shape can permanently change or damage or arrange the resin in the spider. So it seems a controlled break in is recommended to loosen the spider and the resin in the spider, that way the resin structure in the spider isn't over-extended and the intergrity of the resin isn't compromised. Spider problems could easily lead to linearity problems, so maybe think about it from that perspective. I'm trying to get you guys and myself genuine answers. I'm not swinging my wiener around for the fun of it. I'm trying to find what the truth is, and it seems there's multiple truths with breaking in woofers. That's why I really say it's system by system dependent. I also add that the woofer will cool the coil better when it's broken in; stiff spider means coil doesn't move much, air doesn't circulate quite as well through the motor venting and what not. Anyways, that's all I have for now. [/QUOTE]
