Hello all i'm in need of some help i have been trying to find the Fs, QTS, VAS, Xmax, Znom, Pe, Spl, for my DD9518g

I have not been able to get help from Digital Designs customer support other that i should use their box design and the spec's are unnecessary.

Gonna take a shot in the dark and see if anyone out there has a woofer tester that i could borrow or perhaps some has a 9518g they could test for me to find this info i would greatly appreciate the effort or any suggestions.

Sub Sonic was to be building my box and without this info my box will not come to fruition

why do you need all that for an SPL driver? i'd just use the volume/port/tuning that DD recommends.

I have no idea why these specs are important, all i know is the fella building my box would like them. This sub will used for daily driving.

again the specs are useless and you can't interpret them to figure out the holy grail of boxes. Like everyone including the manufacturer has said, build the box to DD specs

Ever built a box to DD spec? I did once worst sounding box i have ever had! Not recommended.

^ well, I guess that's why you need the specs. I really don't know why DD wouldn't have them for this driver anyway...they have them for all the others. Besides, it's in our natures as car audio nuts to want these technical tid bits...we always hate being told to do things this way or that way. We want to discover, experiment, f**k it up a few times, and start again. It's the only way we'll be happy!

lol, i never look at the specs. they dont really matter. 99% of the time, the box you gonna make is application related, rather than the subwoofer spec oriented.
