i got onto the e designs website it tells you the name of the sub and price but no where do i see the size
Stupid and retarded go hand in hand with eDuh //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifya thats the stupidest thing ive ever heard of
They aren't the only one's that do that.ya thats the stupidest thing ive ever heard of
So by that line of reasoning, the IDMAX (as well as the ID v.3) should be classified as a 13" driver, too.Alright, so based on subs with a COMPARATIVE xmax...hell, these subs have LESS xmax than the 13Kv.2 that you posted and less cone area to boot:
RE RE 12:
480 cm² Sd
12mm xmax
JL Audio 12W3V3:
520 cm² Sd
13 mm xmax
13Kv.2:
545cm² Sd
15.1 mm xmax
So, the 13Kv.2 has more cone area than those two subs with a more conventional surround while offering more xmax.
For the subs you show that have the VERY tall surrounds:
Image Dynamics IDMAX:
545 cm² Sd
24.6 mm xmax
TC Sounds TC-3000:
452 cm² Sd(their site lists 240mm diameter = 12 cm radius^2 * PI for that #)
30 mm xmax
I'd certainly hope the drivers that are going to move 9.5+ mm farther one way will have a taller surround.
The IDMAX driver has the same cone area, and more xmax, and it has a much taller surround. That TC driver has less cone area and more xmax.
Granted, it might not quite have the same cone area as what a 13" driver with a conventional cone would be, but it's definitely got more than a conventional 12" driver with an equal xmax.
