All Heritage models are rated at 100 watts continuous 400 peak but they play so loud with so little power its unlikely you will be able to tolerate the volume they can produce with 50 watts.....
I have a pair of Heresy III, 40 watts will drive them plenty loud and clear. Ridiculously loud and not really even pushing the amps. Lascalas are much more efficient, so you wont approach your amp's max power if being sensible with the volume control
