Why get an XXX over an Alpine Type X?

The Type R would dominate both the X and XXX and vin diesel

15 and a 13... XXX had the cone area. And it's install dependant

Not true, you guys are forgetting the whole surround thing W7's got going on, JL says it them selves when they ask alot about why no 15's and why the hell a 13.5? that the 13.5 has the same SD as youre regular 15's with a normal surround, so technically each sub starting from the 8 has the sd of the next sub up.

The 12" XXX is often recommended as the sub to get. But why would anyone pick it over an 12" Alpine Type X?
Take a look at the graphs. Both subs are in ported boxes of 2 cu ft. The Alpine hits an amazing 20 Hz at -3dB! That's on par with HT sub setups. The XXX however hits a more modest 26 Hz at -3dB. Anything below -3dB results in the sub playing the signal at less than 1/2 power when compared to 0dB. Now, the XXX has an SPL advatange of around 2dB until 25Hz. At that point, the Type X outputs a higher SPL by a large amount. At 20 Hz the Type X has a 5-6 dB advantage in SPL over the XXX, a very large amount. Now, I must admit I have not heard either sub and am only going off of what people have told me and the numbers/graphs I see. People say both subs are excellent for SPL and SQ. Why then does it seem atleast to me that the XXX is so much more popular of the Type X when the Type X seems to be the better sub?

Isnt a 15xxxs sd about 810 and the jl around 690? Bout 20% difference, so nice try. If the xxx surround was smaller the sd would be even larger, dont forget that //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif.
