I agree. While the HDC3 is AQ's high end sub, people comparing it to subs like the DC Level 5 or Nightshade is laughable, because there's no way the HDC can handle that much power...
But on the other hand, I agree that the HDC3 isn't an ideal choice for someone who owns a 1000-1200W amp. It simply takes more power than that to get them moving.
The SDC can handle 900 daily though. Mine got stinky, but not warm at all. And that was with no electrical...so with a clean signal I can see it taking 1k all day long.
