Hey everyone, for my new box I need T/S parameters for 9515sc (SPL, Re, Rms,. MMs, MMd, Le, Sd, Vas, Cms, P, xmax, Rms, Q (es, ms, ts)) and motors parameters: Bl,...

Most important parameters for our calculate are: X-max, Le, Re, Bl.

Please help me with this, because on page aren't parameters for 9515h SuperCharged.

Thanks!

I have specs on the 9518H Supercharged as I measured them myself -- but not a 15" sorry!

You can see them here for the 18 :

RE: 4.45 ohms
FS: 41.11 Hz
Qes: 0.34
Qms: 4.44
Qts: 0.32
Le: 4.08 mH
Vas: 72.85 L
Sd: 176 in^2
BL: 35.79 NA
Mms: 379.82 g
Cms: 39.45 uM/N
Sens: 93.46 dB 1w/1m
BL^2/RE: 287.85

These are fresh out of the box on a brand new speaker.

Wow, thanks, but parameters for 15" are very diffrent from 18" sub.
Can you tell me, how did you measured them, because DD don't tell me this parameters...

Thanks!

Woofer Tester II unit -- purchased from Parts Express.

If you have a regular 9515H specs the supercharged option is really only for higher BL -- so just plug that in and reverse calculate the other specs that are effected.

DD's will change parameters pretty much after break-in period, so I see no sense in using "fresh out of the box" measured parameters for any kind of action, especially designing a enclosure.

Again... very simple... use DD's spec for the 9515H "regular" which I'd assume is broken in then plug in the higher BL spec from the SC option. A free program like WinISD Pro can then reverse calculate Qts, Qes, etc that will change with the BL increase.

Yes that's true, that DD change their parameters after break-in, but, can you tell me, where I can find parameters for 9515H regular?
I don't know why DD's parameters are so secured informations...

Thanks!
