For those who have been considering the Nemesis RS700 bass head, but didn't know the power ratings @ 4 ohms and @ 8 ohms (because they're not very well publicized), I just heard back from a rep at US Music Corp. - the company that owns the Eden and Nemesis brands. Power ratings for the Nemesis RS700 are as follows: 400 watts @ 8 ohms 550 watts @ 4 ohms 700 watts @ 2 ohms According to this rep, the RS700 is built to operate @ 2 ohms without any extra stress on the amp. So feel free to connect your dual 4-ohm cabs and fire that baby up! MM
