Go to Termpro and ask around some one there may have specs for the woofer. Or at least be able to give you an idea about it.

Here's some pics I just took of my Ground Zero 10" Radioactive sitting with my Orion HCCA 12D.

yea, my magnet is a double stack. i just took it outta the box - and i have it on my lap. id take a picture but i dont know where my mom stashed the camrea.

ill do it tomrrow.

looks just like that tho.

//edit

it looks to me like the **** of your cone is smaller.

yours might be a newer version. the magnet at the bottom just looks thicker, not double stacked and the bottom cap is more rounded than mine- mine is angular.

do you know the specs of that woofer?

I remember the other models having the bigger dust caps in the same generation as mine....so it is possible that they are from the same year. I see I wrote on my box .77 cubic feet. and THINK I got that number from the original specs The guy who used to work for them told me to add line the edges with fiberglass insulation and add a lb of polyfill. I added the polyfill just now (it had about 2 ounces in it before) and will audition it tomorrow...he told me that from memory to make it sound better and said he wa going to look up the specs for me. I'll PM you.

thanks alot for the info... mine definatly has a larger dustcap, between that and the surround i have maybe .5" where it looks to be more like 1" on yours, other than little cosmetic differences, they seem to be the same drivers.

so we have a match i believe =)

what now?

Take more pics of it and keep posting them on Termpro, giving them all the info you can. Also Id go ported with the sub just so you can see what it can really do. Just keep posing on the termpro thread those will be the guys that can probably help you ou the most.

WinISD or any other program will be able to figure the rest of the parameters out for you. And yes, those are both US GZ products. BTW...give that Nuke 10 more than 750 watts if you can. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif ...and vent both drivers, especially that Nuke!

 

[req 5,000+ posts]

wait, your saying mine is a better driver than his because it has a larger dustcap and this is the difference, aside from TS of the two? the look identical!?
