DiBo Posted September 12, 2018 Report Share Posted September 12, 2018 My fi audio Team 15 is supposed to have a FS around 31... My subwoofer was 47 when new. Is this normal? Btw, I know this because I was there when fi checked it. Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted September 12, 2018 Report Share Posted September 12, 2018 So why didnt you ask them this question? That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

After he checked it he casually mentioned"it'll come down when broken in" and I left it at that. Sounds nothing like my other team 15 dual 2...

CleanSierra Posted September 12, 2018 Report Share Posted September 12, 2018 Get those spiders loosened up and broken in and you should land around manufacturer Fs. I'm not guessing on this one, measured several Crossfire XS series subs from new to broken in to verify. Team suspension is pretty damn stiff from the initial build. It will loosen up and hit much lower as it breaks in. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
SnowDrifter Posted September 12, 2018 Report Share Posted September 12, 2018 Yes. The FS is the resonating frequency of the moving mass of the driver with respect to the mass of the parts and the stiffness of the suspension. Crudely, it can be expressed as Fs=stiffness/mass. As the suspension loosens up, the FS will come down. Likewise, when you have drivers with different cone sizes, the Fs changes not due to different suspension used, but because different cones have different masses ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
