One thing I noticed when I had my 2 12" JBLs, they rattled a lot but that's because of the prefab boxes. Most sub/box combos are tuned to around 40Hz which causes this. My current box for the DC sub is around 32Hz and when it plays notes in the higher range 40-60Hz, it's not as harsh. But, on the low end around 28-34Hz, there is a ton of pressure.
