i hear they reach full excursion with like 300rms and i thought i heard that over 300rms will void your warrenty with em, not possitive, i think glass or jonathan could help you better, i've never personally dealt with adire...
yes i have also heard 300rms should do them justice. never heard about the warranty thing though. also RMS will depend slightly on enclosure. sealed = a little more . ported = a little less.
