Trying to figure out how much (clean RMS-peak) power a driver can take in relation to xmax. I guess the bottom line is.. is it best to stay within the parameters of max spl in winisd and call it good unless a guy had the capability to actually measure the driver in the correlating enclosure himself and not count on the reg spl tab and go with that regarding expectations and putting a clamp on a over powered amp for the application.
