these are only double stacked strontium magnets i think???
if so it is 1 less than the 9500(d) series, and those are rated at 1600 rms, 2400 music, and 4800 peak
and the 9000 series should be a little less than the 9500's rating of 1600rms
so around 1000
they are diesel subs, i have seen them first hand and not much different between them and the 9500 series, except for the magnet
