Funny how you have made the same error in your profile on four other forums.

They weren't in any way stressed so that's not very likely.
Surely that's exactly what you'd expect? Or are you saying you would expect the drivers breaking in to be imperceptible? Heated comment was about this thread... Not the speakers!

Your third paragraph is something different; that's almost certainly thermal compression. As the gig progresses the voice coils heat up and their electrical resistance (reactance in the case of a coil) increases as the temperature rises (and since they're coils that resistance will vary with frequency) ; as the coil temperature rises their output will reduce and as a consequence volumes will be turned up and it becaomes a vicious circle - it's like Ourobos the snake that eats its' own tail.

If your vaccinations were mandatory and nobody in your class had measles,
then you know that you're not a Millenial kid.</f |

This is exactly what i had assumed. I guess it depends if you're happy to wait for them to break in in cab or need them pre done. Testing etc or just want them ready to sound as they will broken in from minute 1. I know my subs sounded different at the end of the night compared to the start of the night the first time I used them as they were loaded with drivers straight out of the box. I'd assumed this breaking in was the same as it would have been if I'd done it in free air but never found anyone with any kind of proof, hence my first post in the thread. Not sure why it got so heated. Seems a fairly simple question if someone had data!

When science and concepts that are globally accepted in the audio community get debated as opinions, and put against arguments made of limited "soundman experience" supported by some random technical blurbs, it already defeats the objects of the forum, wich should be sharing and developing knowledge as far as i am concerned, not fighting it with middle age attitude, like often Elliot seems to do, with a language that sounds dangerously knowledgeable to the newbys. As stated we already lost Kyle round here, who was providing an unvaluable insight from a pro audio outlet and sharing load of technical aspects about how it is done in 2020 (and not "how ye ole soundmen used to do it back in the days") , tired of this attitude. I am relatively new around here, and not a loud person, so I was hesitant to post this, call names or to get lost in flamy debates, but i really feel sorry for this as i see the level and interest going down. This is indeed the place for roots sounds and classic sound systems, but not exclusively, there is also people interested in running o designing sounds with modern concepts and understanding and discussing the advancements of the craft, and this kind of attitude is pushing those people away. We did ban Efinque recently, but I doubt he did as much harm to the forum with his posts. about the thread matter, Klippel suggests there is a measurable fs shift.

An interesting thread here.
Here's my take on it: A lot of the major driver manufacturers have video's showing their finished products being tested to make sure the T/S parameters are to spec. I'd assume the ones that don't pass are scrapped/re-coned. These tests are often quite rigorous sessions with tones that really get the cones moving. So essentially a driver has had a small amount of 'breaking in' done as part of it's manufacture/testing. Drivers that are designed to have a low Fs are generally very stiff when new and you'll struggle to move them by hand with out puncturing the cone. They do always loosen up with age so the sound must change. So i'd say a driver comes partially 'broken in' from new and the sound will change over time. It probably varies with different drivers as to how much so there is really no universal answer to this. BTW guys really sad to see people falling out over differences of opinion on a forum used for discussion. It kind of defeats the object really especially when we're all interested in the same subjects. |

Sound is subjective. So you will always get various answers based on user experience. Have you downloaded REW? It will allow you to measure the TS Parameters of a driver in addition to measuring the frequency response of your finished design. You can also read this to get a basic understanding of TS Parameters and where the PD 186 driver stands Best Regards, Edited by Elliot Thompson - 31 March 2020 at 10:24am |
