it isn't power per se so much as power into a lower impedance - there are impedance curves online for at least some models
IIRC, they get to about 4 ohms at higher freq.s
I use a Sunfire Cinema Grand biamping 1.5 QRs in a big room with no problems at all
BTW, easier load to drive than most electrostatics
