Why do PA concert/club Subwoofers seem not to move when they thump (very loudly)?
And in car audio subs, the subwoofers (same size, diameter, box, power) move up and down ever so visibly (1" excursion, multiple drivers, 1200 watts RMS)
PA concert Subs probably have a better sensitivity level (or, effieciency) so they probably dont need as much power as a car subwoofer, since they're powered much less, they probably would not require more power anyway since they go pretty loud, and more power means a subwoofer will have more excursion. Also Concert Subs Are not designed for excursion (Surround rubber is not really thick).
